U.S. President Donald Trump said Monday he will "substantially" raise tariffs on imports from India, linking the move to New Delhi’s continued purchases of Russian crude. In a post on his Truth Social platform, Trump claimed India is buying “massive amounts” of Russian oil and reselling part of it on the open market for profit, adding that the country "doesn’t care how many people in Ukraine are being killed by the Russian war machine." The president did not detail the size or timing of the new duties, but the threat follows his earlier suggestion of a 25% levy on Indian goods. The escalation risks deepening trade frictions between Washington and New Delhi, which had already failed to finalise a broader trade accord this year. India has been the biggest buyer of seaborne Russian crude since Western sanctions took effect, importing roughly 1.75 million barrels a day in the first half of 2025, according to trade data cited by Reuters. Indian Oil Corp, the country’s largest refiner, has meanwhile booked 7 million barrels of U.S., Canadian and Middle-East crude for September arrival after domestic refiners recently paused tenders for Russian supply. Trump’s comments briefly lifted global oil prices and drew renewed attention to the administration’s push for secondary trade penalties aimed at curbing Moscow’s energy revenue. Indian officials have not publicly responded to the latest tariff threat but previously signalled they intend to keep sourcing oil from a range of suppliers, including Russia.
