US Passes Lindsey Graham Act Authorizing 100% Tariffs on Russian Energy Buyers

US President Donald Trump has signed into law the Lindsey O Graham Sanctioning Russia and Iran Act of 2026, granting the administration sweeping authority to impose tariffs of up to 100 percent on major global purchasers of Russian crude oil and natural gas. The legislation marks the first major Ukraine-related sanctions package to clear the US Congress in more than two years, having advanced through the Senate last month and secured bipartisan passage in the House.

The 48-page statute honours the late Republican Senator Lindsey Graham, who spent over a year negotiating the legislative framework before passing away in July at age 71 from an aortic dissection. Co-authored with Democratic Senator Richard Blumenthal, the measure targets Russian President Vladimir Putin, senior government officials, oligarchs, and major financial institutions, while also attacking Moscow's energy sector and the shadow fleet of oil tankers operating outside Western restrictions.

The most contentious provision of the new statute grants the White House discretionary authority to levy tariffs of up to 100 percent against the five largest importers of Russian energy. Trade data compiled by the Centre for Research on Energy and Clean Air indicates that China accounted for 50 percent of Russian crude exports between December 2022 and August 2026, with India absorbing 37 percent during the same timeframe. Turkey and the European Union each accounted for 5 percent, though European purchases have steadily declined.

The legislation features narrow structural exemptions, sparing nations that import less than 15 percent of their natural gas supply from Russia and can demonstrate active efforts to reduce their foreign energy dependency. Despite these carve-outs, the primary mechanism places unprecedented secondary pressure on major emerging economies that rely heavily on discounted Russian petroleum.

The bill's journey through Congress involved rare cross-party collaboration, securing 58 Democratic votes in the Senate and advancing through procedural hurdles in the House after two opposition lawmakers crossed party lines. Proponents argue the statutes apply maximum economic leverage to degrade Moscow's military supply chains.

Ukrainian President Volodymyr Zelenskyy praised the legislation as an extremely powerful tool, urging swift implementation. House Speaker Mike Johnson asserted the measures squeeze the Russian war machine, while Senator Blumenthal told Putin during debate that lawmakers have his number. Conversely, House Minority Leader Hakeem Jeffries opposed the measure, warning that its broad tariff powers would inflate domestic costs for American consumers and arguing the enforcement mechanisms contain significant loopholes.

Reacting to the looming tariff exposure, Indian officials emphasized that the nation remains firmly committed to ensuring energy security for its 1.4 billion citizens. The diplomatic friction arrives at a delicate juncture, preceding Trump's scheduled White House meeting with Chinese President Xi Jinping.

Implementation rests entirely with the executive branch's willingness to invoke the newly codified tariff levers against major trading partners. While Washington frames the statutes as a definitive lever to force negotiations, international compliance remains uncertain as major importers balance domestic energy demands against potential US trade penalties.
