The "hellish sanctions" law mandates the U.S. president to impose tariffs of up to 100% on goods from five countries that are actively purchasing Russian oil and gas or helping Moscow circumvent sanctions, to be implemented within 30 days. An exception applies to nations sourcing less than 15% of their gas from Russia and reducing their dependency. Former President Donald Trump may suspend the tariffs for national security reasons, leaving implementation decisions to the White House. China and India are expected to be most affected.
