Event_Log
011928Tariff autonomy law enactedCorrelationExpected causation
New customs tariff law (11 Ordibehesht 1307) restores Iran's autonomy to set its own import tariffs, cancelling Qajar-era treaty limits on Iranian customs duties and introducing an ad valorem tariff structure.
Why this link: This 1307 (1928) law is the founding legal act that gave Iran sovereign control over its own import tariff schedule, the exact policy lever these applied-tariff-rate charts track.
Caveat: Modern applied tariff rates reflect many subsequent revisions (WTO-era liberalization, sanctions-era import substitution) rather than the 1928 schedule itself.
Lag: Nearly a century of subsequent revisionSource: Encyclopaedia Iranica (Commerce vii. In the Pahlavi and post-Pahlavi periods)0219861986 oil price collapseCorrelationExpected causation
Saudi Arabia abandons its swing-producer role; oil prices crash from ~$27 to under $10/barrel, straining every oil-exporting economy in this database (Saudi Arabia, Venezuela, USSR, Iran).
Why this link: Fuel's share of merchandise exports directly tracks the world price of oil; the 1986 collapse mechanically depressed the value (though not necessarily volume) of Iran's dominant export category.
Caveat: Value share also depends on non-oil export growth, which was minimal during the war economy.
Lag: Same year.Source: US Energy Information Administration0320032000s commodity super-cycleCorrelationExpected causation
China's post-2001 WTO-driven infrastructure boom, alongside strong global growth, drives the IMF commodity price index up roughly fourfold between January 2000 and mid-2008; crude oil rises from about $30/barrel in 2003 to a record $147/barrel on 11 July 2008, delivering a sustained fiscal windfall to every oil exporter in this database (Iran, Saudi Arabia, Venezuela, Russia) before the Global Financial Crisis abruptly ends the cycle.
Why this link: The fuel share of merchandise exports rose with the price boom, since Iran's non-oil export base grew far more slowly than the oil windfall.
Caveat: Some of the rise also reflects stagnation in manufactured and agricultural export competitiveness, a separate domestic story.
Lag: Same year.Source: US Energy Information Administration··2003Iraq War beginsCorrelationExpected causation
US-led invasion halts roughly 2 million barrels/day of Iraqi oil production; global crude prices spike toward $40/barrel before Saudi Arabia and other OPEC members raise output to offset the loss, averaging $30/barrel for 2003 overall (up 19% from 2002).
Why this link: Post-Saddam Iraq rapidly became one of Iran's largest export markets for consumer goods, food, and construction materials, a structural shift traceable to the 2003 regime change.
Caveat: The trade relationship built up gradually over subsequent years and also depended on Iran's own export-promotion policy and sanctions-driven regionalization of trade.
Lag: 2-5 years.Source: Middle East Research and Information Project (MERIP)042008Global Financial Crisis — Lehman Brothers collapseCorrelationExpected causation
Triggers a synchronized global recession; oil prices crash from ~$147 to ~$40/barrel within months, hitting every oil exporter in this database simultaneously, while credit-driven European economies (Spain, Portugal, Greece) enter prolonged crises.
Why this link: The current-account surplus, dominated by oil exports, contracted sharply as export revenue collapsed with the oil price.
Caveat: Import compression in response to the shock also affected the balance, partly offsetting the export-side drop.
Lag: Same to next year.Source: Federal Reserve History052015Iran nuclear deal (JCPOA) signedCorrelationExpected causation
Iran and the P5+1 finalize the Joint Comprehensive Plan of Action in Vienna, exchanging nuclear-program limits for the lifting of UN, EU and US nuclear-related sanctions; roughly $100bn in frozen Iranian assets are released after IAEA-verified implementation begins in January 2016.
Why this link: Sanctions relief beginning in January 2016 allowed Iran to roughly double its oil exports within a year, directly lifting fuel's share of merchandise exports.
Caveat: The recovery in export volume was also constrained by upstream investment shortfalls after years of underinvestment, so the rebound was not as complete as sanctions relief alone would predict.
Lag: 6-12 months (implementation began January 2016).Source: European External Action Service062018US withdraws from the JCPOACorrelationExpected causation
President Trump announces US withdrawal from the Iran nuclear deal and directs the phased reimposition of all sanctions lifted in 2015-16, with full "snapback" effective 5 November 2018, reversing the 2015 sanctions-relief framework and re-isolating Iran's oil and banking sectors from the dollar system.
Why this link: Snapback sanctions from November 2018 cut Iran's oil exports by roughly two-thirds within a year, a direct and well-documented collapse in the fuel share of merchandise exports.
Caveat: None significant: the mechanism (US secondary sanctions on oil buyers) and the export data are both well documented and closely aligned in timing.
Lag: Within 6 months of the November 2018 snapback.Source: OFAC — May 2018 Guidance on Reimposing Certain Sanctions with Respect to Iran072020COVID-19 declared a pandemicCorrelationExpected causation
WHO declaration triggers synchronized global lockdowns, an oil-demand collapse (WTI briefly trades negative on 20 April 2020), and unprecedented fiscal/monetary stimulus across every country in this database.
Why this link: International tourist arrivals to Iran collapsed with global travel restrictions in 2020, a direct and near-universal effect of pandemic lockdowns on cross-border travel.
Caveat: Iran's tourism sector was already constrained by sanctions-related banking and visa friction before the pandemic.
Lag: Immediate, within months.Source: World Health Organization··2022Russian invasion of UkraineCorrelationExpected causation
Triggers sweeping Western sanctions on Russia, a global energy-price shock benefiting other oil/gas exporters (Iran, Saudi Arabia, Venezuela partially re-engaged by the West for supply), and a European inflation surge affecting Spain, Portugal, Greece.
Why this link: Western sanctions on Russia deepened Iran-Russia economic cooperation (barter arrangements, sanctions-evasion trade routes, and a 2023 free-trade agreement), a structural shift in Iran's trade relationships traceable to this event.
Caveat: The scale of this shift within Iran's aggregate merchandise export figures is modest relative to the still-dominant role of oil, and much of the increased cooperation runs through channels not fully captured in official trade statistics.
Lag: 1-2 years.Source: OFAC — Russia-related sanctions

Laws related to this measure. Correlation = how closely this law tracks this measure's story. Expected causation = how strongly we would expect it to have moved the line. Neither is a claim of proof.
1929CorrelationExpected causationAct Authorizing the Application of the Minimum Customs Tariff to Merchandise from Iraq
Authorizes applying the minimum customs tariff rate to merchandise originating from Iraq.
Why this link: Sets a minimum customs tariff specifically for trade with Iraq, one of many bilateral tariff arrangements that together made up Iran's early tariff regime shaping import costs.
Caveat: No chart in this database isolates Iran-Iraq trade or 1920s-era tariff levels; the link is included only as part of the broader tariff-policy backdrop to modern import-tariff series.
1951CorrelationExpected causationAmendment to Note 4 of the Act on the Amendment and Implementation of the Customs Tariff
Amends note 4 of the act governing the amendment and implementation of Iran's customs tariff.
Why this link: This 1951 amendment to note 4 of the customs-tariff implementation law gives government purchases preference to barter-basis imported goods, a trade-policy tool affecting the composition rather than the tariff level of imports.
Caveat: This is a narrow procurement-preference rule, not a tariff-rate change; its effect on aggregate import volumes or tariff-rate series is indirect and cannot be isolated.
Lag: Immediate for government procurement decisions1958CorrelationExpected causationCustoms Tariff Amendment Act
Passed in 1958, this law revises Iran's customs tariff schedule, sets import duty and customs handling fee rates, exempts transit, re-exported and transshipped goods from import duty, exempts all exports from export duty, and authorizes retaliatory tariffs against countries that discriminate against Iranian exports.
Why this link: This law amended Iran's customs tariff schedule, the core legal instrument setting import duty rates across product categories; as a structural reform of the tariff schedule itself it bears directly on the whole family of tariff-rate measures and on customs revenue.
Caveat: Modern WDI tariff-rate and customs-revenue series generally do not extend back to 1958, and Iran's tariff structure has been repeatedly re-legislated since, so this specific 1958 amendment cannot be traced in the plotted modern data; its relevance is structural/historical.
Lag: Within the years following enactment (1958 onward).1968CorrelationExpected causationAct Authorizing the Determination of Customs Ground-Rent and Warehousing Fees
Authorizes the government to set customs ground-rent (storage) and warehousing fees.
Why this link: Authorizes setting customs storage and warehousing fee rates, a cost component of clearing imports through customs that feeds into overall logistics/customs-clearance efficiency and effective import costs.
Caveat: The logistics-performance index only exists for the modern era, long after this 1968 law, and warehousing fees are a minor share of total trade costs relative to tariffs, exchange rates and sanctions.
1985CorrelationExpected causationExport and Import Regulations Act of 1985 (1364)
Passed in 1985 as that year's annual foreign trade law, this act requires a business card for commercial import and export activity, sorts goods into permitted, conditional and prohibited categories, and assigns import authorization power to the Ministry of Industry, Mines and Trade.
Why this link: The Law on Export and Import Regulations (1364/1985) is the foundational statute governing which goods may be traded, licensing, prohibited/restricted lists and the tariff-setting mechanism for Iran's foreign trade; it is the direct legal instrument behind Iran's post-revolutionary trade regime and remains the base law amended by later annual foreign-trade regulations.
Caveat: Actual trade flows in this period were dominated by war-economy rationing (1980-88), then sanctions and oil-price cycles; the law set the legal architecture but volumes moved mostly with these larger forces.
Lag: Ongoing framework effect from enactment (1985) through subsequent annual amendments.1986CorrelationExpected causationExport and Import Regulations Act of 1986 (1365)
Passed in 1986 as that year's annual foreign trade law, this act requires a business card for commercial trade, sorts goods into four categories, permitted, conditionally permitted, restricted and prohibited, and delegates authorization power to the Ministry of Industry, Mines and Trade.
Why this link: The 1365 (1986) Export-Import Regulations Act, enacted during the Iran-Iraq war economy, was the core statutory framework governing licensing, permitted/prohibited goods and customs procedure for all trade, amended a year later by the 1366 version; it is the direct legal basis underlying the country's merchandise trade series in this period.
Caveat: Trade volumes during the war years were dominated by wartime disruption, rationing and oil-export dependence far more than by this regulatory framework itself.
Lag: Structural, ongoing over the law's period of force.1986CorrelationExpected causationAmendment to Article 53 of the Executive Bylaw of the Export and Import Regulations Act for the Year 1365 (1986)
On 29/05/1365 AH (1986), the Cabinet raised the mandatory foreign-exchange repatriation rate (payman-e arzi) that exporters had to surrender on certain export goods, from 75 to 85 percent for one category and from 25 to 35 percent for another, and eliminated a discount clause that had applied to a third category.
Why this link: This 1986 amendment to Article 53 of the Import/Export Regulations executive bylaw adjusted licensing/procedural detail within the core administrative framework that governs all recorded merchandise trade.
Caveat: A narrow single-article technical amendment; its own contribution to trade volumes cannot be separated from oil revenue, sanctions, and exchange-rate policy, the much larger drivers of these series.
Lag: Administrative effect near-immediate.1986CorrelationExpected causationDecree Adding a Note to Article 3 ... Executive Bylaw of the Export and Import Regulations Act for the Current Year
This decree adds a note to Article 3 of the executive bylaw implementing that year's Export and Import Regulations Act.
Why this link: This 1986 cabinet decree adds a note to Article 3 of the import/export regulations bylaw, a minor procedural amendment within Iran's core annual trade-licensing regime.
Caveat: A narrow textual amendment to an existing bylaw clause; its effect cannot be isolated from the many other rules governing that year's trade regime.
Lag: Immediate upon promulgation for that trade year.1987CorrelationExpected causationExport and Import Regulations Act (1987)
Passed in 1987, this earlier version of Iran's annual foreign trade law made import and export of any good subject to this act and repealed conflicting rules; it was later implicitly superseded by the 1993 Export and Import Regulations Act of the same name.
Why this link: This is Iran's core statutory framework governing all export and import regulation (licensing, prohibited/permitted goods lists, customs procedures); it is the direct legal instrument underlying the country's entire merchandise trade series.
Caveat: Actual trade volumes are driven mainly by oil prices, sanctions and global demand; this framework law sets the rules of the game rather than moving trade values directly.
Lag: Structural, ongoing over the law's period of force.1987CorrelationExpected causationExecutive Bylaw of the Export and Import Regulations Act (1987)
Issued in 1987 to implement that year's Export and Import Regulations Act, this bylaw sets the administrative procedures for trade licensing, including a minimum six-month validity for ministry import/export authorizations and designation of deprived border regions eligible for special trade treatment.
Why this link: This 1987 executive bylaw implements Iran's core Export-Import Regulations Law, the operational rulebook governing licensing and procedures for most of Iran's foreign trade during the war-economy and early post-war years.
Caveat: Trade volumes and values in this period were dominated by the Iran-Iraq War, multiple exchange-rate regimes, and sanctions, so the bylaw's specific procedural effect cannot be separated from these much larger forces.
1988CorrelationExpected causationExecutive Bylaw of the Export and Import Regulations Act (1988)
Issued in 1988, this bylaw implements that year's Export and Import Regulations Act, prescribing administrative procedures such as inter-ministerial committee review of import and export requests and a minimum six-month validity period for trade authorizations.
Why this link: This 1988 implementing bylaw operationalized Iran's Export and Import Regulations Act, setting the licensing, permitted/prohibited goods lists, and procedural rules that governed the entire foreign-trade regime through the late Iran-Iraq War and postwar reconstruction period.
Caveat: Trade volumes in this period were dominated by wartime shortages, foreign-exchange rationing, and the multiple-exchange-rate system, so the bylaw's specific contribution to export or import values cannot be separated from those larger forces.
1988CorrelationExpected causationResolution Adding Two Clauses to Article 43 of the Executive Bylaw of the 1988 Export and Import Regulations Act
Approved in 1988, this resolution lets ministries with manufacturing subsidiaries use foreign-exchange proceeds from barter exports to countries in the Eastern or Western bloc to import raw materials and machine parts for those plants, with the exchange rate set equal to the bank's purchase rate for that hard currency.
Why this link: Adopted near the end of the Iran-Iraq War in 1988, this bylaw let ministries with industrial companies use export foreign-exchange proceeds to barter-import raw materials and machine parts from Eastern- and Western-bloc countries, part of the war-economy's improvised trade and FX-allocation arrangements.
Caveat: It applied to a narrow set of state industrial companies and barter partners; total wartime trade flows were shaped far more by sanctions, oil-revenue collapse and shipping disruption than by this specific clause.
Lag: Immediate for covered firms; economy-wide effect negligible.1989CorrelationExpected causationApproval of Article 50 Bis of the Executive Bylaw of the Export and Import Regulations Act
This decree approves the addition of article 50 bis to the bylaw implementing Iran's Export and Import Regulations Act.
Why this link: This 1989 addition to the executive bylaw of the Export/Import Regulations Law came amid Iran's post-war reconstruction opening of trade policy, shaping the procedural framework for the trade flows recorded in these series.
Caveat: Trade volumes in this era were dominated by post-war reconstruction demand and the recovery of oil revenue; the specific contribution of this procedural addition cannot be isolated.
Lag: Same fiscal year to the next.1989CorrelationExpected causationCabinet Resolution on Converting the Note to Article 28 into ... the Executive Bylaw of the Export and Import Regulations Act
Passed by the cabinet on 14 Mordad 1368 (1989), this resolution amends the bylaw to require that cash incentive awards for non-oil exports be adjusted according to international prices and the production costs of exported goods, with the Article 26 Commission submitting proposals to the Export Development Committee.
Why this link: This 1989 decree converts a clause into a standalone article within the Import/Export Regulations executive bylaw, part of the postwar reconstruction-era overhaul of the trade licensing regime.
Caveat: A structural/drafting change to the bylaw; cannot be isolated from the broader postwar trade liberalization measures affecting the same series.
Lag: Administrative effect near-immediate.1989CorrelationExpected causationDeletion of a Phrase from the Resolution Exempting Automobiles Needed by the Military Forces from Clause (c) and the Remarks of Chapter 87 of the Table Annexed to the Executive Bylaw of the Export and Import Regulations Act
This decree deletes a phrase from the resolution that exempted automobiles needed by the military forces under clause (c) and the remarks of Chapter 87 of the tariff table annexed to the Executive Bylaw of the Export and Import Regulations Act.
Why this link: This 1989 decree removes a phrase from an exemption clause of the Import/Export Regulations bylaw, narrowing a specific customs exemption within Iran's trade-licensing regime during the war-reconstruction period.
Caveat: Removing one exemption phrase is a minor technical tightening; against the scale of postwar trade disruption and the exchange-rate regime, its own effect is not separable.
1990CorrelationExpected causationAct on the Addition of a Note to Clause 1 of the Export and Import Regulations Act of the Year 1368 (1989/90)
This law adds a note to clause one of a provision within the Export and Import Regulations Act of the Iranian year 1368.
Why this link: Adds a clause to the implementing bylaw of the Export/Import Regulations Law, part of the routine machinery that sets which goods may be traded and under what licensing conditions.
Caveat: A single clause addition to an implementing bylaw; too narrow and technical to move aggregate trade series on its own.
1990CorrelationExpected causationDecree Adding Certain Phrases to a Part ... Executive Bylaw of the Export and Import Regulations Act
This decree adds certain phrases to a part of the executive bylaw implementing the Export and Import Regulations Act.
Why this link: This 1990 cabinet decree inserts wording into the import/export regulations implementing bylaw, a minor procedural amendment to the annual trade-licensing regime during the early post-war period.
Caveat: A narrow textual insertion; its effect cannot be isolated from the broader trade-liberalization steps of the early 1990s.
Lag: Immediate upon promulgation.1991CorrelationExpected causationAmendment to the Executive Bylaw of the Export and Import Regulations Act
This decree amends the bylaw implementing Iran's Export and Import Regulations Act.
Why this link: This 1991 amendment to the executive bylaw of the Export/Import Regulations Law updated the goods-classification and licensing regime governing which items could be freely traded, conditionally traded, or banned, directly bearing on import and export volumes.
Caveat: As with periodic bylaw amendments generally, its isolated contribution to trade volumes is hard to separate from broader postwar reconstruction-era trade liberalization steps taken in the same years.
Lag: Trade-flow adjustments generally follow within the same or following fiscal year.1991CorrelationExpected causationDecree on Adding Four Clauses to a Part ... Executive Bylaw of the Export and Import Regulations Act
This decree adds four clauses to a part of the executive bylaw implementing the Export and Import Regulations Act.
Why this link: This 1991 decree adds four new clauses to the Import/Export Regulations bylaw, a more substantive package of trade-policy changes than a single-note amendment, plausibly touching several categories of licensed goods.
Caveat: Even a four-clause addition remains a technical amendment inside a much larger bylaw; it cannot be isolated from the rest of the trade-licensing regime or from broader macro trade drivers.
1991CorrelationExpected causationAmendment to Article 48 of the Executive Bylaw of the Export and Import Regulations Act
Passed by the cabinet on 25 Ordibehesht 1370 (1991), this resolution removes the requirement for 'the relevant ministry's determination and approval' as a condition for importing goods without foreign-currency transfer, under the bylaw's article on such imports (the source text notes the intended article was likely 41, misnumbered as 48).
Why this link: This 1991 amendment revises Article 48 of the Import/Export Regulations bylaw, one more procedural clause within Iran's standing trade-licensing and customs framework.
Caveat: As a narrow procedural amendment, its own effect on aggregate trade or customs figures cannot be separated from the bylaw's many other provisions or from external trade shocks.
1991CorrelationExpected causationAmendment to Note 4 of Article 37 of the Executive Bylaw of the Export and Import Regulations Act
This amends Note 4 of Article 37 of the executive bylaw implementing the Export and Import Regulations Act.
Why this link: This 1991 amendment revises note 4 of Article 37 of the same Import/Export Regulations bylaw, another procedural adjustment within Iran's standing trade-licensing and customs framework.
Caveat: Its scope is a single clause within a large standing bylaw, so any effect on trade volumes cannot be separated from the bylaw's broader provisions or from external trade shocks.
1993CorrelationExpected causationExport and Import Regulations Act
Passed in 1993, this law is Iran's core foreign trade statute, classifying goods into permitted, conditional and prohibited categories for import and export and requiring a business card for commercial trading, with the Ministry of Industry, Mines and Trade issuing import authorizations.
Why this link: The Export/Import Regulations Law is Iran's foundational national statute setting the legal framework for all foreign trade, the explicit instrument governing which goods may be traded, licensing, and trade policy administration.
Caveat: Trade volumes and values are heavily driven by oil prices, sanctions regimes, and exchange rates; the law sets the framework but does not itself determine trade flows.
1993CorrelationExpected causationDecree on the Implementation of the Executive Bylaw of the Export and Import Regulations Act for the Year 1372 (1993/94)
This decree governs implementation of the executive bylaw of the Export and Import Regulations Act for the year 1372 (1993/94).
Why this link: This 1993 decree formally puts the Import/Export Regulations executive bylaw into force for the 1372 (1993/94) trade year, making it the direct legal basis for that year's licensing and customs terms, a more immediate link to the corresponding year's trade figures than a routine clause amendment.
Caveat: Even as the year's governing instrument, it operationalises a pre-existing regulatory framework rather than introducing new policy, so it cannot be credited with shifts in trade volumes driven by prices, demand or sanctions that year.
1994CorrelationExpected causationAmendment to the Executive Bylaw of the Export and Import Regulations Act
This amends the executive bylaw implementing the Export and Import Regulations Act.
Why this link: This 1994 amendment revises the executive bylaw of Iran's Import/Export Regulations Law, the core administrative instrument governing which goods may be traded and under what customs terms, so it forms part of the regulatory backdrop to Iran's merchandise trade and customs-revenue series.
Caveat: This is a routine administrative revision within a much larger, continuously amended bylaw; its own marginal effect cannot be separated from the bylaw's dozens of other simultaneous provisions or from macro trade drivers like sanctions and the exchange rate.
1995CorrelationExpected causationAmendment to Note 2 of Article 31 of the Executive Bylaw of the Export and Import Regulations Act
This decree amends Note 2 of Article 31 of the executive bylaw of the Export and Import Regulations Act.
Why this link: This 1995 amendment revises the duty-free and reduced-duty value bands for goods carried by incoming travelers, a minor personal-imports carve-out within the general Export-Import Regulations bylaw.
Caveat: Passenger baggage allowances are far too small in scale to move national merchandise-import statistics.
Lag: Immediate.1997CorrelationExpected causationAmendment to the Executive Bylaw of the Export and Import Regulations Act
This amends the executive bylaw implementing the Export and Import Regulations Act.
Why this link: This 1997 amendment further revises the same executive bylaw of the Import/Export Regulations Law, continuing the incremental tightening or loosening of Iran's customs and trade-licensing terms that underlie its recorded import and export series.
Caveat: As one incremental revision among many to the same standing bylaw, its isolated contribution to trade flows cannot be distinguished from the cumulative regulatory regime or from oil-price and sanctions cycles.
1998CorrelationExpected causationAmendment to the Executive Bylaw of the Export and Import Regulations Act
Approved in 1998, this amendment revises the border-trade provisions of the Export and Import Regulations bylaw, defining the border districts eligible for border-trade cards, setting a $200 million annual import ceiling for border residents and their cooperatives, and capping each cardholder's duty-free annual export and import value at 500,000 rials.
Why this link: This 1998 amendment to the executive bylaw of Iran's Export/Import Regulations Law reset the annual list of permitted, conditional and prohibited goods and the licensing procedures traders had to follow, directly shaping the volume and composition of import and export flows.
Caveat: The bylaw is one of many annual/periodic trade-regulation amendments; its specific effect cannot be separated from concurrent exchange-rate, tariff and sanctions dynamics.
Lag: Effects on trade flows typically appear within the same fiscal year as licensing rules change.1998CorrelationExpected causationAmendment to the Executive Bylaw of the Export and Import Regulations Act
This amends the executive bylaw implementing the Export and Import Regulations Act.
Why this link: This 1998 amendment revises the executive bylaw of the Import/Export Regulations Law, another routine step in the ongoing administrative regulation of Iran's trade-licensing and customs regime.
Caveat: This is one of many similar amendments to the same standing bylaw; its isolated contribution to trade or customs figures cannot be separated from the rest.
1998CorrelationExpected causationAmendment to Note 1 of the Amended Article 15 of the Executive Bylaw of the Export and Import Regulations Act
This amends Note 1 of the previously amended Article 15 of the executive bylaw implementing the Export and Import Regulations Act.
Why this link: This 1998 amendment changes note 1 of Article 15 of the Import/Export Regulations bylaw, a specific customs-procedure clause within the law that structures Iran's trade-licensing regime.
Caveat: A single-note amendment is too narrow to isolate in the aggregate trade series; it should be read as one of many procedural tweaks to the same standing regulation.
1999CorrelationExpected causationAmendment to the Note under Clause 2 of Article 38 of the Executive Bylaw of the Export and Import Regulations Act
This amendment revises the note under clause 2 of article 38 of the bylaw implementing Iran's Export and Import Regulations Act.
Why this link: This 1999 amendment altered the executive bylaw governing Iran's foreign-trade licensing and procedural regime, the framework through which most merchandise trade flows are administered.
Caveat: Procedural trade-regulation amendments are one of many determinants of trade volumes alongside oil prices, sanctions, and exchange-rate policy, and their specific effect on any single trade series is hard to isolate.
Lag: Procedural effects on trade flows typically show within the same or the following fiscal year.2000CorrelationExpected causationAmendment to the Executive Bylaw of the Export and Import Regulations Act
This amends the executive bylaw implementing the Export and Import Regulations Act.
Why this link: This 2000 amendment further revises the executive bylaw of the Import/Export Regulations Law, one more increment in the continuous administrative fine-tuning of Iran's customs and trade-licensing terms.
Caveat: As a routine incremental revision, its own effect cannot be separated from the cumulative regulatory regime or from the exchange-rate and sanctions environment of the year 2000.
2000CorrelationExpected causationExecutive Bylaw of the Act on Government Discretionary Punishments for Goods and Currency Smuggling
Issued in 2000, this bylaw implements the 1995 Government Discretionary Punishments (Ta'zirat) Act for smuggling, defining agencies such as the "discovering agency" and setting procedures for revenue bodies like customs and the central bank to pursue and penalize smugglers, including confidential rewards for informants.
Why this link: The same anti-smuggling enforcement regime also targets illicit, undeclared trade in goods, so it bears indirectly on the accuracy and level of Iran's recorded merchandise trade statistics.
Caveat: Smuggled goods are by definition outside recorded trade statistics, so this law's effect shows up mainly as a gap between recorded and actual trade rather than a visible movement in the official series.
2002CorrelationExpected causationAmendment to the Executive Bylaw of the Export and Import Regulations Act
Approved by the Cabinet in 2002, this amendment changed the import-license validity period set in Article 10 of the Executive Bylaw of the Export and Import Regulations Act from a fixed five years to a flexible one-to-five-year term set according to the applicant's request.
Why this link: This 2002 amendment to the Import/Export Regulations executive bylaw updates the core administrative rules governing merchandise trade licensing during the Khatami-era trade liberalization drive.
Caveat: A procedural amendment; its own effect on trade volumes cannot be isolated from the broader liberalization package of the period.
Lag: Effect, if any, within the same year.2002CorrelationExpected causationAmendment to the Executive Bylaw of the Export and Import Regulations Act
Passed by the cabinet on 15 Aban 1381 (2002), this amendment revises Article 11 of the bylaw to set new deadlines, from 10 to 55 days depending on origin and mode of transport, for goods imported without foreign-currency transfer to enter the country under pre-existing permits, and it repeals Article 29 of the bylaw.
Why this link: This 2002 amendment to the executive bylaw of the Export-Import Regulations Law sets transitional shipping deadlines for goods licensed before an import restriction changed, a narrow customs-administration adjustment within Iran's general trade-licensing framework.
Caveat: It is a procedural transition rule affecting a small share of shipments already in the pipeline, not a change to tariff or licensing policy itself.
Lag: Immediate, one-time transitional window.2002CorrelationExpected causationDecree No. 33578/T26504H Dated the 15th ... Concerning Government Discretionary Punishments (Ta'zirat) Related to the Smuggling of Goods and Currency
This decree, numbered 33578/T26504H, concerns discretionary punishments for the smuggling of goods and currency.
Why this link: This 2002 amendment restructures how confiscation proceeds and informant bounties are distributed among anti-smuggling agencies under Iran's Law on Discretionary Punishments for Goods and Currency Smuggling, part of the state's enforcement apparatus against informal trade.
Caveat: It only reorganizes internal revenue-sharing among enforcement bodies and has no direct, measurable effect on recorded import volumes or values.
Lag: N/A, administrative only.2003CorrelationExpected causationAct to Amend Certain Provisions of the Third Development Plan Act on Establishing and Collecting Duties and Other Charges from Goods Producers, Service Providers and Imported Goods (the Duties Consolidation Act)
Enacted in 2002 (1381), this law, known as the Duties Consolidation Act, unified Iran's scattered import duties and production and service taxes into a single schedule, for example a flat 4 percent customs charge on imports plus set rates on cigarettes, soft drinks, gasoline, telecom services and vehicle registration; it was repealed in 2008 when the Value Added Tax Act took effect.
Why this link: Amends Third Development Plan provisions specifically governing providers of imported goods and services, a named regulatory channel to import composition and terms.
Caveat: A targeted amendment affecting a specific class of importers; aggregate import series are dominated by oil revenue, exchange rates, and sanctions.
2003CorrelationExpected causationExecutive Bylaw of Clause (Kh) of Note 19 of the National Budget Act for 1382 (2003)
Issued in 2003, this bylaw set up a wheat-for-flour licensing scheme under which qualified domestic mills could import wheat meeting government quality standards and were required to export an equivalent quantity of flour, with the Grain Trading Company of Iran coordinating quality controls and delivery.
Why this link: This 2003 implementing bylaw for a clause of the FY1382 budget law set procedures for importing wheat for milling and re-exporting flour, a narrow trade-facilitation scheme layered onto Iran's wheat-import and milling industry.
Caveat: A narrow, single-year procedural bylaw for one budget clause; Iran's wheat trade volumes are driven far more by harvest size, the guaranteed purchase price, and broader import policy than by this scheme.
Lag: Effects, if any, would be confined to the trade flows of the year the bylaw was in force.2003CorrelationExpected causationRuling No. 232 of the General Board of the Administrative Court of Justice ... Article 6 of the Executive Bylaw of the Export and Import Act
This ruling addresses article 6 of the bylaw implementing Iran's Export and Import Act.
Why this link: This administrative-court ruling struck down a single clause of the executive bylaw governing import/export regulation, a narrow legal correction to the trade-licensing framework rather than a standalone policy change.
Caveat: The annulment of one clause is too narrow to have a measurable, isolable effect on aggregate trade series; it is included only for completeness of the legal record.
Lag: Any effect would be immediate upon the ruling's enforcement.2004CorrelationExpected causationAmendment to Articles 30 and 31 of the Executive Bylaw ... on Discretionary Punishments Concerning the Smuggling of Goods and Currency
This decree amends Articles 30 and 31 of the executive bylaw on government discretionary punishments for smuggling goods and currency.
Why this link: Amends procedural articles of the bylaw implementing discretionary punishments for smuggling of goods and currency, part of the enforcement apparatus against unofficial trade and capital flight.
Caveat: A narrow procedural amendment to two articles; smuggling volumes are driven far more by the exchange-rate gap and sanctions than by this enforcement tweak, so its own effect on recorded trade or FX series cannot be isolated.
Lag: Enforcement effects, if any, would show within the same fiscal year.2004CorrelationExpected causationRuling No. 95 of the General Board of the Administrative Court of Justice, on Port Rights, Duties, and Fee Tariffs
This ruling by the Administrative Justice Court's General Board addresses tariffs for port rights, duties, and fees.
Why this link: Lower/altered port fees marginally change the landed cost of imported goods, one of many small frictions affecting import volumes.
Caveat: Overwhelmed by exchange-rate movements and sanctions, which dominate import-volume swings.
2007CorrelationExpected causationAmendment to Article 4 of the Executive Bylaw of the Export and Import Regulations Act, Approved in 1372 (1993/94)
This amends Article 4 of the executive bylaw of the Export and Import Regulations Act, which was approved in 1372 (1993/94).
Why this link: This 2007 amendment revises Article 4 of the Import/Export Regulations bylaw, a tariff/customs-classification clause with a named, if narrow, channel to Iran's customs-duty revenue.
Caveat: A single-article tariff clarification is small relative to the scale of Iran's customs-revenue swings, which are driven far more by trade volume, exchange rates and sanctions.
2008CorrelationExpected causationAddition of Text as Note (3) to Article (16) of the Traffic Regulations for the Free Trade-Industrial Zones of the Islamic Republic of Iran
This decree adds note 3 to Article 16 of the traffic regulations governing Iran's free trade-industrial zones.
Why this link: Amends the bylaw for free trade-industrial zones, which carry customs and tariff exemptions designed to attract trade-oriented investment, part of the policy backdrop to Iran's import flows.
Caveat: Free trade zones account for a small share of total Iranian imports, so this bylaw amendment cannot be isolated as a driver of the national import series.
2010CorrelationExpected causationDecree of the Members of the Economic Commission Replacing the Texts of Clauses (2) and (3) of Article (10) of the Executive Bylaw of the Export and Import Regulations Act
This decree by the Economic Commission ministers replaces the wording of clauses (2) and (3) of Article 10 of the Executive Bylaw of the Export and Import Regulations Act.
Why this link: This 2010 Cabinet Economic Commission decree amended Iran's foreign trade regulations bylaw, the executive instrument that governs the licensing, prohibited/restricted lists and procedures underlying Iran's entire merchandise import and export flows.
Caveat: As a broad procedural amendment it shapes the trade regime generally, but aggregate export and import values in this period were dominated by oil prices and, from 2011 onward, escalating sanctions, so the decree's own contribution to the totals cannot be isolated.
Lag: Within 1-2 years as licensing procedures adjust.2013CorrelationExpected causationAnti-Smuggling of Goods and Currency Act
Passed in 2013, this law is Iran's principal anti-smuggling statute, defining goods and currency smuggling, establishing specialized courts and enforcement task forces, and setting penalties such as confiscation and fines, with a share of recovered funds paid as rewards to whistleblowers and enforcement agencies.
Why this link: By criminalising unlicensed goods movement across borders, the law targets the informal trade flows that sit outside officially recorded import/export statistics.
Caveat: Smuggled trade is by definition unmeasured, so enforcement effects on the official trade series can only be inferred indirectly.
2014CorrelationExpected causationDecree on the Addition of Clause (dh) to Article (2) of the Executive Bylaw on the Collection of Charges in the Free Trade-Industrial Zones of the Islamic Republic of Iran
This decree adds clause (dh) to Article 2 of the executive bylaw governing the collection of charges in Iran's free trade-industrial zones.
Why this link: This 2014 decree adds a clause to the executive regulations of Iran's Free Trade-Industrial Zones Law, adjusting the customs/tariff instruments available inside zones such as Kish, Qeshm and Chabahar, which is part of the trade-policy apparatus behind Iran's recorded import and export flows.
Caveat: A single added clause to a zone-level bylaw is a marginal adjustment; it cannot be isolated from the far larger drivers of national trade volumes such as oil prices, sanctions and the exchange-rate regime.
2015CorrelationExpected causationAddition of Clause 3 Bis to Article 11 of the Executive Bylaw of the Export and Import Regulations Act
This decree adds clause 3 bis to article 11 of the bylaw implementing Iran's Export and Import Regulations Act.
Why this link: This 2015 clause made a narrow procedural addition to the executive bylaw of the Export/Import Regulations Law, part of the ongoing fine-tuning of Iran's trade-licensing framework.
Caveat: As a narrow procedural clause, its effect on aggregate trade series is negligible next to the sanctions, currency controls, and global oil prices dominating this period.
Lag: Same fiscal year.2015CorrelationExpected causationRuling No. 784 of the General Board of the Administrative Court of Justice [...] the Executive Bylaw of the Export and Import Regulations Act
This ruling by the General Board of the Administrative Court of Justice addresses a provision of the executive bylaw of the Export and Import Regulations Act.
Why this link: 2015 Administrative Court ruling voiding a clause of the Import/Export Regulations Article-1 Commission's 2011 decree, arising from a dispute over the licensing and duties applied to a shipment of imported feed wheat, feed corn and food wheat.
Caveat: A single case-driven ruling on one clause of a national import-licensing decree; its effect on aggregate customs revenue or cereal import volumes cannot be separated from the underlying regulatory regime and broader import demand.
2016CorrelationExpected causationRulings No. 729-737 of the General Board of the Administrative Justice Court: Annulment of Central Bank Circulars on Importers' Payment of the Reference-to-Trading Exchange-Rate Differential
Issued in 2016, this ruling of the Administrative Justice Court's General Board struck down several 2013 Central Bank circulars that had required importers to pay, at customs clearance, the gap between the subsidized reference exchange rate and the market trading rate, where that obligation had not been agreed in the original financing contract, finding the retroactive charge contrary to Islamic law.
Why this link: This 2016 court ruling concerns fees imposed on goods importers, a narrow procedural matter within the broader import-cost and tariff regime this category tracks.
Caveat: A ruling on one specific fee item is too narrow to move aggregate import values or tariff-rate indices measurably.
Lag: None separately observable.2017CorrelationExpected causationAmendment to Article 5 of the Executive Bylaw of Articles 5 and 6 of the Anti-Smuggling of Goods and Currency Act
This decree amends Article 5 of the bylaw implementing Articles 5 and 6 of the law combating the smuggling of goods and currency.
Why this link: This 2017 amendment orders the Central Bank, together with the Ministry of Industry and customs, to build and operate a currency-tracking system under the 2015 Anti-Smuggling of Goods and Currency Law, part of the state's effort to formalize FX flows and narrow the gap between official and informal exchange rates.
Caveat: The official-parallel FX gap is driven overwhelmingly by sanctions, monetary policy and expectations; a single tracking-system amendment cannot be credited with moving it.
Lag: System build-out took years after the underlying 2015 law.2017CorrelationExpected causationAmendment to Added Note (5) of Article (11) of the Executive Bylaw of the Export and Import Regulations Act, with Subsequent Amendments and Additions
This decree amends added Note 5 to Article 11 of the executive bylaw of the Export and Import Regulations Act.
Why this link: This 2017 amendment clarifies when goods warehoused in Iran's free trade and special economic zones are deemed to have formally entered the customs territory, a technical customs-timing rule under the general Export-Import Regulations bylaw.
Caveat: It affects the accounting timing of a subset of free-zone transit goods, not the overall level of imports.
Lag: Immediate.2018CorrelationExpected causationAddition of Notes 5 and 6 to Article 8 of the Amendment ... Free Trade-Industrial Zones of the Islamic Republic of Iran
This adds Notes 5 and 6 to Article 8 of the law governing the free trade-industrial zones of the Islamic Republic of Iran.
Why this link: This 2018 amendment adds two tariff/duty notes to Article 8 of the Free Trade-Industrial Zones Law's executive bylaw, a specific customs-duty channel with a more direct, named link to import-duty revenue than a generic procedural clause.
Caveat: The provision applies only within free trade-industrial zones, a small share of total trade, so its measurable footprint on the national customs-revenue series is limited.
2018CorrelationExpected causationAmendment to Decree No. 49751/T55549H ... Executive Bylaw of the Export and Import Regulations Act
This amends Decree No. 49751/T55549H concerning the executive bylaw of the Export and Import Regulations Act.
Why this link: This 2018 amendment to the government decree implementing the Import/Export Regulations bylaw updates trade-administration procedure during the sanctions-era trade regime.
Caveat: A procedural update; its own effect cannot be separated from the dominant sanctions and exchange-rate shocks of the same period.
Lag: Effect, if any, within the same year.2018CorrelationExpected causationRuling No. 1221 of the General Board of the Administrative Court of Justice ... Concerning a 2 Percent Charge on Plastic Goods, Cartons, and Other Items
This ruling by the General Board of the Administrative Court of Justice concerns a 2 percent charge applied to plastic goods, cartons, and other items.
Why this link: This 2018 ruling addresses a 2% duty/fee on plastics, cartons and similar goods, a narrow product-specific matter within the broader import-cost regime.
Caveat: A 2% fee on a narrow set of product categories is too small and specific to move aggregate merchandise import values measurably.
Lag: None separately observable.2021CorrelationExpected causationAmendment to Article 9 of the Bylaw on the Manner of Use of ... Free Trade-Industrial Zones of the Islamic Republic of Iran
Amends article 9 of the bylaw governing the use of resources in the free trade-industrial zones of the Islamic Republic of Iran; the source title is truncated in the original record.
Why this link: Amends the bylaw on use of facilities (customs/trade incentives) in free trade-industrial zones, a customs and trade-policy instrument shaping conditions for firms importing through these zones.
Caveat: In the sanctions-and-currency-crisis era of the early 2020s, free trade zone facility rules are a minor factor next to exchange-rate policy and sanctions in determining national import volumes.
2025CorrelationExpected causationCustoms Circular on Updating the Following Tariff Codes in the List of Goods Subject to Percentage-Based Clearance
This circular updates certain tariff codes on the list of goods eligible for percentage-based customs clearance.
Why this link: This 2025 customs circular updates the tariff-code list for goods cleared under the percentage-based clearance regime, a routine administrative refresh of import classification codes.
Caveat: A routine tariff-code list update is too narrow and too recent to show any measurable, isolable effect on aggregate import series.
Lag: Any effect would be immediate and confined to the specific goods list.2025CorrelationExpected causationCustoms Circular on Updating the Following Tariff Codes in the List of Goods Subject to Percentage-Based Clearance
This circular updates certain tariff codes on the list of goods eligible for percentage-based customs clearance.
Why this link: This 2025 customs circular updates the tariff-code list for goods cleared under the percentage-based clearance regime, a routine administrative refresh of import classification codes.
Caveat: A routine tariff-code list update is too narrow and too recent to show any measurable, isolable effect on aggregate import series.
Lag: Any effect would be immediate and confined to the specific goods list.
