Trump signs Russia-Iran sanctions law, opens door to 100% tariffs on India
The Sanctioning Russia and Iran Act of 2026 was signed into US law, expanding sanctions on Russia's energy, defence, and financial sectors and extending the Iran Sanctions Act for five years.
The law authorizes tariffs of up to 100% on goods from countries — potentially including India and China — that continue to purchase Russian crude oil or natural gas, or that facilitate evasion of Russia-related sanctions.
The provision targeting large buyers of Russian oil and gas is discretionary: it grants the US executive branch broad authority to decide which countries face the additional tariffs, rather than imposing them automatically on any named country.
The law also expands measures against Russian financial institutions, defence-related entities, and the "shadow fleet" of vessels used to move Russian energy exports while circumventing existing restrictions.
Secondary Sanctions and CAATSA — the Precedent for India
Secondary sanctions are measures a country (typically the US) imposes not on the sanctioned state itself, but on third countries or entities that continue to transact with it — extending the reach of sanctions extraterritorially. India has direct prior experience with this mechanism through the Countering America's Adversaries Through Sanctions Act (CAATSA), 2017.
Key Details
- CAATSA, signed into law in August 2017, imposes secondary sanctions (Section 231) on entities/countries conducting "significant transactions" with Russia's defence or intelligence sectors, alongside sanctions related to Iran and North Korea.
- India faced potential CAATSA exposure over its 2018 contract (~US$5.4 billion) to purchase five S-400 Triumf air defence systems from Russia; the US government has used discretionary waiver authority (expanded by the 2019 National Defense Authorization Act) rather than imposing sanctions on India, citing strategic partnership considerations.
- Turkey, by contrast, was sanctioned under CAATSA in 2020 for an equivalent S-400 purchase — showing that waiver decisions are discretionary and India-specific treatment is not guaranteed by law alone.
The new Act follows the same "secondary sanctions with executive discretion" template as CAATSA — the law creates the authority to impose 100% tariffs on major Russian oil/gas buyers like India, but whether it is actually exercised against India depends on a case-by-case US policy decision, exactly as with the S-400 waiver precedent.
India's Russian Oil Imports and Strategic Autonomy
Since 2022, India has substantially increased imports of discounted Russian crude oil, becoming one of the largest buyers alongside China, while maintaining that its energy purchases are a sovereign economic decision consistent with its position of strategic autonomy in foreign policy.
Key Details
- India's stated position is that energy security for its 1.4-billion-strong population is a legitimate national interest, and that it does not violate any UN Security Council sanctions (Russia sanctions are unilateral US/EU measures, not UNSC-mandated).
- The G7 price cap mechanism (December 2022) sought to limit Russian oil revenue while keeping supply flowing to global markets; India's purchases have generally been framed by New Delhi as compliant with this cap where applicable.
- Tariff or sanctions action against India's oil trade would represent a unilateral, discretionary US trade measure rather than a multilaterally sanctioned WTO-consistent restriction.
The new Act's 100% tariff authority is aimed precisely at countries like India that have continued significant Russian energy purchases post-2022, making India's response — diplomatic engagement versus diversification of crude sources — a live foreign-policy and trade-policy issue.
Presidential Tariff Authority vs WTO Tariff Bindings
Tariffs imposed under domestic sanctions legislation (like this Act) are a unilateral executive tool, distinct from tariffs negotiated and "bound" under WTO schedules. A 100% tariff imposed this way would sit outside normal WTO tariff-binding commitments and could be challenged as WTO-inconsistent, though sanctions-related national security exceptions (GATT Article XXI) are often invoked as justification.
Key Details
- GATT Article XXI allows members to take actions "necessary for the protection of essential security interests," a provision frequently invoked to justify sanctions-linked trade measures outside normal WTO discipline.
- Bound tariff rates under WTO schedules represent ceilings a member has committed not to exceed for normal trade; national-security or sanctions-based tariffs are argued as falling outside this discipline, a contested legal position.
The Act's authorization of tariffs "up to 100%" on Indian goods would far exceed India's WTO-bound tariff commitments if applied reciprocally, illustrating why such measures are typically framed under national-security exceptions rather than ordinary trade law.
- Act signed: 2026 (Sanctioning Russia and Iran Act of 2026).
- Maximum discretionary tariff authorized: up to 100% on goods from countries significantly importing Russian crude oil/gas or facilitating sanctions evasion.
- Iran Sanctions Act extended by: 5 years.
- CAATSA (precedent secondary sanctions law) enacted: August 2017.
- India's S-400 contract value: approximately US$5.4 billion (signed 2018).
- Turkey sanctioned under CAATSA for S-400 purchase: 2020 (contrast case to India's waiver treatment).
