The U.S. Department of Homeland Security has issued a formal notice imposing an additional 25 percent tariff on all Indian-origin goods, doubling effective duties to as much as 50 percent. The measure, announced by President Donald Trump earlier this month, takes effect at 12:01 a.m. EDT on Wednesday, 27 August, and is framed as a response to New Delhi’s continued purchases of discounted Russian crude despite Western price-cap efforts. Under the notice, the higher levy will apply to any shipment entering U.S. commerce from early Wednesday, with limited exemptions for in-transit cargo, humanitarian aid and goods covered by reciprocal trade programmes. Textiles, leather, processed foods, marine products and other labour-intensive exports are expected to bear the brunt of the increase. The prospect of steeper duties has already rattled Indian markets: the rupee slipped 0.17 percent to 87.73 per dollar at Tuesday’s open, while the Sensex fell 543 points to 81,093 and the Nifty 50 shed 165 points to 24,803. Indian officials said exporters affected by the tariffs would receive financial assistance and were urged to diversify toward China, Latin America and the Middle East. Prime Minister Narendra Modi’s government has yet to secure any delay or relief and continues to defend its energy strategy, with Foreign Minister Subrahmanyam Jaishankar arguing that price-cap policies implicitly acknowledge ongoing purchases of Russian oil.
