The United States has moved closer to imposing 100 percent tariffs on at least five countries, including India and China, over allegations that they have purchased large quantities of crude oil and other energy products from Russia.

On Friday, the US Senate passed a bill aimed at enabling such punitive measures. The legislation, titled the “Russia and Iran Act of 2026,” was introduced by the late Senator Lindsey O. Graham, a close ally of President Donald Trump, who died on July 11.

The bill proposes that the United States could impose a 100 percent tariff on countries that, despite sanctions, have continued to purchase significant quantities of Russian oil and energy products, thereby providing financial support to Russia during the war in Ukraine.

Of the 100 members of the Senate, 86 voted in favor of the bill, 11 voted against it, and three abstained.

Following its passage in the Senate, the bill will now be sent to the House of Representatives, where it is expected to be taken up after the chamber resumes its session on August 31.

If the bill secures a majority in the House, it will then be sent to the White House for presidential approval. It will become law if signed by the US president.

If enacted, the legislation could put not only China and India but also at least three other countries—Azerbaijan, Hungary and Slovakia—at risk of facing the proposed tariffs.

These countries remain dependent on Russia for oil and gas supplies and have maintained varying levels of that dependence despite the ongoing Russia-Ukraine war.
