Bharat Petroleum bought one or two cargoes of US crude that were recently diverted from its original destination of China, Refineries Director R Ramachandran said in an interview. He didn’t identify the seller, how big the shipments were, or the name of the ships. It’s possible BPCL could buy more American oil that was headed to China, he said.

Beijing announced it would impose the 5 per cent levies -- the first ever Chinese tariffs on US oil -- on Aug 23 and they took effect Sept 1. Six tankers carrying about 12 million barrels of US crude were on the way to China at the time of the announcement. At least one of those vessels arrived before the deadline, while another ship may have offloaded its cargo at a port near Qingdao before the tariffs took effect.

Unipec -- the trading arm of China’s state-owned oil giant Sinopec -- offered US crude that couldn’t arrive in the Asian country before Sept. 1 in late August. At least three potential Asian buyers received offers from Unipec, according to people with knowledge of the matter.

Indian refiners have increased their purchases of American oil this year as supplies from Iran and Venezuela were hit by White House sanctions. The Asian nation bought an average of 287,000 barrels of US crude a month in this year through May, compared with a monthly average of 131,000 barrels in 2018, according to Energy Information Administration data.

China was the biggest foreign buyer of American crude as recently as the middle of last year but imports were subsequently slashed as the trade dispute worsened. Purchases picked up again this year, reaching 1.5 million tons in July, data from the General Administration of Customs show.

Ramachandran also said BPCL is looking to process US West Texas Intermediate Light and Louisiana Light Sweet crude, two American grades that the Indian refiner has yet to purchase.
