India’s largest conglomerate Reliance Industries, owned by billionaire Mukesh Ambani, has stopped importing Russian crude oil for its export-only refining unit at Jamnagar in the western state of Gujarat.

The move is to ensure compliance with an EU announced ban on import of fuel made from Russian oil coming through third countries starting next year and US sanctions on top Russian oil producers Rosneft and Lukoil, that are set to kick-in on Friday.

“This transition has been completed ahead of schedule to ensure full compliance with product-import restrictions coming into force on 21 January 2026,” Reliance said in a statement.

The White House has welcomed the move by Reliance.

“We welcome this shift and look forward to advancing meaningful progress on US-India trade talks,” the White House press office said, in a statement to the Washington Post.

Delhi’s purchase of Russian oil has been a major sticking point between India and the US. Trump slapped India with 50% tariffs in August, including a 25% penalty for buying Russian oil and arms, which he says was funding Moscow’s war on Ukraine – a charge India has denied.

India’s purchases of discounted Russian oil shot up from barely 2.5% of imports before the war began in 2022, to around 35.8% in 2024-25.

Reliance is India’s largest importer of Russian oil, and accounts for around 50% of Russian oil flows into the country.

The Jamnagar refinery is the largest single-site refining complex in the world – with two separate units dedicated for exports and the domestic market.

Mounting global pressure appears to be having a desired effort on India after months of resistance from Delhi to reduce oil purchases from Moscow. Over the past couple of months, oil refiners in India have been lowering their imports, according to several reports.

Reliance reduced orders from sanctioned Russian companies by 13% while increasing monthly imports from Saudi Arabia to 87% and Iraq to 31% in October, according to a Carnegie Endowment report.

Indian state-controlled refineries are also skipping Russian crude imports for December contracts according to Bloomberg.

Given India has sharply curtailed its imports, Washington must “immediately scrap the additional 25% tariff on Indian goods”, Ajay Srivastava of the Global Trade and Research Initiative (GTRI) think-tank said.

“Maintaining the tariff despite India meeting US expectations undermines goodwill and risks slowing already delicate trade negotiations,” Mr Srivastava said.

Negotiations for a broader trade deal between India and the US have been severely hampered by the former’s Russian oil purchases, but the tensions appear to be gradually letting up after months of uncertainty.
