<h1>U.S. tariffs aimed at curbing India's Russian oil purchases, with threats of rapid hikes and proposed 500% duties</h1> Statements describe a prospective use of U.S. customs measures to discourage India's purchases of Russian oil. The U.S. President indicated that tariffs on Indian trade can be increased 'very quickly' in response to such purchases, implying a possible escalation of import duties as an enforcement lever affecting India's market access to the U.S. A U.S. Senator referenced an existing 25% tariff said to have been imposed on India for buying Russian oil, asserting it has contributed to reduced purchases, and described a proposed tariff bill that would impose 500% import levies on goods from countries that continue purchasing Russian oil, materially increasing duty liability for affected imports if enacted.
