US President Donald Trump has signed the Lindsey Graham Russia and Iran Sanctions Act of 2026, making it law after the measure passed the Senate and House. The law expands US authority to impose primary and secondary sanctions on Russia and entities supporting Moscow, while extending sanctions-related powers against Iran.
Key provisions include:
-
- The law allows the president to impose tariffs of up to 100% on goods from countries that are among the top five buyers of Russian oil and gas or help Russia evade energy sanctions.
-
- Potential targets include Russian officials, oligarchs, banks, financial institutions and the oil “shadow fleet.”
-
- Certain countries may qualify for exemptions if Russian gas accounts for less than 15% of Russia’s total gas exports and they take significant steps to reduce dependence on Russian energy.
-
- For Iran, the law extends the Iran sanctions act for another five years, preserving US authority to sanction Iran’s energy and arms sectors.
-
- The law could affect major Russian energy buyers such as China and India, although the 100% tariffs are presidential powers rather than automatic measures.
The legislation gives the Trump administration broader economic tools against Russia, its energy buyers and Iran, but the actual implementation will depend on future White House decisions.
