Iran Secondary Tariffs: Three Country Tests Congress Could Choose
Trump asked Congress to add Iran tariffs to the Russia sanctions bill. The July 27 sponsor draft contains no Iran tariff authority, and three possible country tests would create different watchlists, evidence files and exit records for importers.

According to Inside Trade's July 29 account of President Trump's remarks, he asked Congress to add Iran tariffs to the Russia sanctions bill and referred to five countries. The public record does not identify those countries or contain an Iran tariff amendment.
Trump's request leaves a country-selection question unanswered. Congress could use the 2024 proposal's petroleum-transaction test, the February order's prohibited-commerce test or the Russia draft's top-five ranking. Each would produce a different watchlist and a different official record for moving a country into or out of scope.
The choice has direct consequences for importers. A narrow Iranian transaction could expose goods from an otherwise unrelated third country to an additional U.S. duty. The legal trigger selects the country; the resulting border measure can reach that country's much wider export portfolio.
The public sponsor draft contains sanctions for Iran, not tariffs
The July 27 public sponsor amendment draft, marked ROS26G03, contains a detailed Russia tariff title. Section 112 would authorize duties of up to 500 percent on Russian goods. Section 113 would authorize duties of up to 100 percent on goods from qualifying third countries. Its country tests are tied to Russian oil, Russian gas and Russian oil sanctions evasion.
Iran appears in Section 201. That provision changes the expiration year in the Iran Sanctions Act from 2026 to 2031. The sponsors' July 28 statement draws the same line: targeted tariffs for major buyers of Russian oil and gas, along with continued sanctions authority covering Iran's energy and weapons sectors. Extending a sanctions statute does not supply a customs duty.
The Senate's 86 to 12 vote on July 28 invoked cloture on the motion to proceed to H.R. 5334. It limited further debate and moved the Senate toward a separate vote on whether to take up the House vehicle. It did not adopt that motion, offer or adopt ROS26G03, pass the sponsor proposal or enact an Iran tariff.
Three official designs would not name the same countries
The first design is S.4761, the Tariffs for Terrorism Act of 2024. Its sponsor draft directed the President to identify any country that purchased, traded, consumed or imported Iranian crude oil or petroleum products. Every country meeting that test would receive the tariff treatment described in the proposal. There was no ranking or five-country limit.
The second appeared in Executive Order 14382. It covered a country that directly or indirectly purchased, imported or otherwise acquired prohibited goods or services from Iran. Commerce would make the country finding. State would decide whether to recommend a duty and its extent, after interagency consultation. The President would then determine whether and to what extent to act.
The third is the Russia structure in ROS26G03. Its initial process reaches a country that makes a qualifying new purchase and ranks among the five largest importers, by volume, of Russian crude oil or natural gas during the preceding 12 months. A separate branch reaches the five largest countries facilitating Russian oil sanctions evasion.
Those are different legislative choices. The petroleum model uses covered transactions with no country cap. The executive-order model extends beyond energy but excludes authorized Iran commerce from its defined trigger. The Russia model adds a rank and a numerical cutoff. An Iran amendment must specify the qualifying conduct and the rule for selecting countries.
Earlier Traverse coverage addressed the distinct question of express tariff authority after Learning Resources. S.1241 Russia Sanctions Deal Still Has No Published Tariff Terms, Traverse Analysis explains why a political agreement does not create an entry rule. The Iran issue begins earlier: what conduct places a third country in scope.
The petroleum test creates a transaction-based watchlist
The S.4761 sponsor draft was broad in consequence and narrow in its trigger. It applied its instruction to any country engaged in the listed dealings with Iranian crude or petroleum products. It then purported to raise duties on all goods and services imported from that country to at least 500 percent.
Services expose an unresolved defect in that text. The draft used the words "goods and services," but it supplied no mechanism for assessing an HTSUS duty on an imported service. The proposal was introduced on July 24, 2024, referred to Senate Finance and did not advance beyond introduction. Its treatment of services was never implemented or tested.
For goods, the monitoring record was more concrete. The President would identify countries within 90 days of enactment and every 120 days thereafter. Federal Register notice would be required at least 45 days before an increase took effect. A country would leave when the President certified to Congress that it no longer engaged in the covered Iranian petroleum trade.
An importer using this scenario would track evidence of covered petroleum transactions and the resulting presidential country record. A company importing footwear, equipment or chemicals from a named country could face the proposed duty even if its own supply chain had no link to Iranian oil.
A service can trigger a country tariff on goods
Executive Order 14382 separated the trigger from the tariff base more cleanly. A country could qualify because it acquired Iranian goods or services. Any duty would be imposed on goods that were products of that country. A service transaction could therefore help create the country finding without becoming the item on which CBP collected the duty.
The order also defined the Iranian commerce that could count. "Goods or services from Iran" included only those for which U.S. persons were prohibited from trading under the cited Iran sanctions regulation. Indirect acquisition included transactions through intermediaries or third countries when Iranian origin could reasonably be traced.
That boundary is important for a future statute. If Congress borrows an any-goods-or-services trigger without preserving a comparable authorization boundary, trade that U.S. law permits could enter the country-designation record unless the amendment creates another exception. The issue is not limited to petroleum. It can reach services and non-energy goods whose origin must be traced through intermediaries.
Executive Order 14382 no longer supplies tariff authority. The Supreme Court held in Learning Resources that IEEPA does not authorize the President to impose tariffs. The same day, Executive Order 14389 ended the additional ad valorem duties authorized under the listed IEEPA orders and directed agencies to terminate collection. The Federal Register text preserved the Iran emergency and other non-tariff actions.
The February order matters here only as a country-trigger design. A congressional amendment would be a new statutory authority with the limits Congress writes.
Five countries is a limit, not an Iran list
ROS26G03 uses more than one top-five process. The initial test in Section 113(c) combines a qualifying new purchase with a preceding 12-month rank for Russian crude oil or natural gas. It also has the separate evasion branch. Section 113(e) then instructs USTR, after 180 days and every 180 days thereafter, to identify separate lists of the five largest crude-oil importers and the five largest natural-gas importers using the most recent 12-month period. That later instruction does not restate the new-purchase condition or refresh the evasion list.
Copying the number five would not tell officials how to rank Iran trade. Congress would still have to select the conduct and metric. Petroleum volume, transaction value, prohibited commerce and sanctions-evasion activity could all produce different results. A combined goods-and-services ranking would also need a way to compare unlike transactions.
The President's reference to five countries should therefore remain outside any current-duty table. Until public text supplies a metric and an authorized process supplies a determination, five is only a possible limit.
Keep the sanctions screen and the country-tariff watchlist separate. Section 8512 addresses Iranian-origin imports into the United States. The requested tariff would address products of a third country selected because of its Iran trade. A supplier can clear party screening while its origin country remains a candidate for a broader border measure.
Under the petroleum test, the monitoring file centers on dealings in covered Iranian oil products and the President's country finding. Under the prohibited-commerce test, it also needs evidence of direct or indirect Iranian origin and the legal boundary between prohibited and authorized trade. A ranked test adds the measurement period, data source and official methodology.
Commercial data can identify candidates. It cannot confer legal status. A media list, cargo estimate or sanctions alert should remain labeled as monitoring evidence unless an authorized public action places the country in scope.
What import teams should do before amendment text appears
Maintain three scenario files outside the live duty model. For each country candidate, record the cited evidence, retrieval date, assumed trigger and legal status. The petroleum file tracks trade in the products named by the 2024 proposal. The prohibited-commerce file tracks evidence tied to the sanctions definition, including its authorization boundary. The ranked file remains hypothetical until Congress defines the metric and responsible agency.
Government affairs should preserve ROS26G03, the July 28 sponsor statement, the Senate floor record and any new amendment as separate documents. The first redline should isolate the Iran-specific duty grant, country trigger, rate limit, agency roles, review interval and exit rule. A statement of support cannot fill a blank in the text.
Sourcing teams can map U.S. import value and critical products by country under each scenario. Rates should remain explicit assumptions. No current record supports treating 25, 100 or 500 percent as the rate Congress will choose for Iran.
When an amendment appears, compare its country test with the three source designs before changing the watchlist. When an authorized implementing action appears, preserve the country determination and its effective treatment before changing a live entry model.
Caveats and what would change the calculus
The C-SPAN event record places the reporter's question at about 34:19 and the President's answer at about 34:28. Its closed captions are uncorrected. Inside Trade provides the contemporaneous account used for the five-country reference. Neither record supplies amendment text or country identities.
New public language could select one of the three models, combine them or create a different test. A fixed country list, commodity scope, numerical threshold, authorization boundary, review schedule or exit rule would change the analysis. So would formal Senate action offering or adopting text that differs from ROS26G03.
The next controlling document is amendment text, not a country estimate. Until Congress defines the trigger and an authorized implementing record names a country, keep all three scenarios outside current-duty tables.
