U.S. President Donald Trump on 6 Aug. signed an executive order imposing an additional 25% tariff on all goods imported from India, doubling the duties that Washington had already announced earlier this year. The White House said the measure responds to New Delhi’s continued direct or indirect purchases of Russian oil, which Washington argues undermine efforts to isolate Moscow over its war in Ukraine. The tariff hike represents the sharpest deterioration in U.S.–India economic relations in more than a decade and follows the collapse of negotiations aimed at forging a broader trade accord. Senior administration officials warned that nations assisting Russia could face further trade penalties or secondary sanctions as part of Washington’s pressure campaign. Trump’s decision comes days after his special envoy, Steve Witkoff, held talks in Moscow seeking progress toward a peace deal in Ukraine, and shortly before Indian Prime Minister Narendra Modi is expected to visit China for the first time in seven years. Analysts said the timing may complicate regional dynamics and could provoke retaliatory steps from New Delhi, which has yet to issue a formal response. The new duties threaten sectors ranging from pharmaceuticals to textiles that rely on the U.S. market, adding fresh uncertainty for exporters on both sides.
