President Donald Trump signed the Lindsey O. Graham Sanctioning Russia and Iran Act of 2026 on Sept. 19, authorizing tariffs of up to 100% on major buyers of Russian energy.
The statute, designated H.R. 5334, equips the White House with discretionary tariff authority against countries that accounted for the top five import volumes of Russian crude oil or natural gas over the past 12 months.
The tariff authority allows the administration to levy punitive duties between zero and 100% across all exported goods from those jurisdictions, according to the legislative text.
India and China represent the primary targets under the statutory volume threshold, according to shipping and cargo tracking records from S&P Global Commodities at Sea.
India imported 1.6 million barrels per day of Russian crude oil in August, representing roughly 35% of its total seaborne crude intake, S&P Global reported.
China imported 1.1 million barrels per day of Russian crude during the same month, while Turkey received 191,000 barrels per day to rank fourth globally.
Under the legislation, duties applied to direct Russian merchandise imports can rise to as high as 500%, according to records from the House Ways and Means Committee.
The law also codifies mandatory sanctions on Russian financial institutions, naming Sberbank and Gazprombank, alongside restrictions aimed at operators and owners of Russia's maritime shadow fleet.
A narrow statutory carve-out shields countries whose Russian gas purchases constitute less than 15% of total Russian gas exports, provided they demonstrate verifiable reduction steps.
Congressional action concluded when the House of Representatives passed the bill by a 262 to 159 vote on Sept. 16, following an 86 to 11 Senate vote on Aug. 7.
The statutory mechanism does not trigger secondary duties automatically, leaving the effective date, exact duty levels and product line coverage entirely to executive determination.
For downstream energy buyers, the tariff authority creates immediate procurement uncertainty, according to trade disclosures from the Indian Ministry of External Affairs.
Indian refiners Reliance Industries and Indian Oil Corporation have processed discounted Russian Urals crude into refined transport fuels, serving both domestic demand and export corridors.
Reliance Industries operates the Jamnagar refining complex in Gujarat, where Russian barrels have constituted an estimated 40% of run rates over the past year.
A blanket tariff penalty on Indian manufactured exports would reach far beyond energy refiners, landing on electronics, automotive subassemblies and active pharmaceutical ingredients bound for American distribution centers.
Contract manufacturers producing mobile devices and electronics in southern India now operate under secondary tariff risk, altering supplier calculations for Western original equipment manufacturers.
Chinese state refiners China National Petroleum Corporation and Sinopec have maintained long-term crude contracts with Russian producers, drawing piped and seaborne volumes into coastal facilities.
If the White House exercises the secondary tariff mandate against Beijing, Chinese consumer hardware and electrical machinery shipments would face immediate cost inflation at United States ports of entry.
The tariff threat arrives as Western corporate procurement directors attempt to balance cost advantages against the expanding perimeter of American economic security legislation.
The White House has not published an executive order or a Federal Register notice establishing specific tariff rates or designated Harmonized Tariff Schedule product codes under the new statute.
The executive branch faces a 30-day statutory window ending Oct. 18, 2026, to issue initial implementation rules and submit required certification frameworks to congressional trade committees.
