India’s Reliance Industries, operator of the world’s biggest refining complex, has purchased 5 million ​barrels of Iranian crude, days after the US temporarily removed sanctions on ‌the oil, three sources familiar with the matter said on Tuesday.

The Indian refiner bought the oil from the National Iranian Oil Co., two of the sources ​said.

One of them said the crude was priced at a ​premium of about $7 a barrel to ICE Brent futures. It was not immediately clear when the oil would be delivered.

Iranian oil, which ​in recent years has mainly been bought by Chinese independent refiners, ​is often rebranded as originating from another country.

Reliance did not respond to emails seeking comment. NIOC could not be reached for comment.

The Trump administration on Friday issued a ​30-day sanctions waiver for the purchase of Iranian oil already ​at sea. The waiver applies to oil loaded on any vessel, including tankers under ‌sanctions, on or before March 20 and discharged by April 19.

The deal marks India’s first purchase of Iranian oil since the world’s third-biggest oil importer and consumer halted imports from Iran in May 2019, months ​after Washington reimposed ​sanctions on Tehran.

The purchase comes after Indian refiners snapped up more than 40 million barrels of Russian crude after the ​US announced a temporary sanctions waiver this month to ease ​supply shortages.
