US President Donald Trump signed the Lindsey O. Graham Sanctioning Russia and Iran Act of 2026 (H.R. 5334) into law on 18 September 2026.
The law lets the US President levy tariffs of up to 100% on the five largest foreign buyers of Russian crude oil and natural gas - a group that includes India and China.
It also allows tariffs of up to 500% on all imports from Russia and up to 100% on countries aiding Russia's 'shadow fleet' of tankers; the powers are discretionary and lapse after five years.
The Act extends the Iran Sanctions Act of 1996 by five years, to 2031.
Russia supplied about 30% of India's crude oil imports in FY 2025-26, and an India-US interim trade deal in February 2026 had already cut US tariffs on Indian goods from 50% to 18%.
Signed 18 September 2026. Widens US sanctions on Russia's energy and defence sectors, its banks and its shadow tanker fleet, and gives the US President discretionary tariff powers of up to 500% on Russian imports and up to 100% on the largest foreign buyers of Russian energy. The tariff authority expires five years after enactment.
The long-standing US law authorising sanctions on investment in Iran's energy sector; the 2026 Act extends it by five years, to 2031.
The Act works by penalising third countries for trading with Russia rather than by sanctioning Russia directly - the legal design that makes India and China exposed even though neither is the target of the law.
