The Lindsey O. Graham Sanctioning Russia and Iran Act of 2026 became law on September 18, ratcheting up the Trump Administration’s pressure to bring Vladimir Putin to the negotiating table and end the Russo-Ukrainian War. It also gives the president new tariff authority for the first time since the Trade Act of 1974 became law 52 years ago. This comes less than seven months after the Supreme Court struck down President Trump’s use of the International Emergency Economic Powers Act of 1977 (IEEPA) to impose his tariff regime.
The Graham Act allows the president to impose sanctions on major entities and figures in Russia tied to its defense industrial base, as well as on any other nations that aid its defense sector or import Russian energy. It also enables the president to increase tariffs on imports of Russian energy by up to 500% ad valorem and levy tariffs of up to 100% ad valorem “on countries that purchase Russian-origin crude oil or natural gas or facilitate sanctions evasion.”
