Imports of Iranian crude by Asia's four main oil buyers increased by about two-thirds in January from a year ago when levels were lower as Western sanctions on Tehran had only just been lifted.
Iran's top four Asian buyers — China, India, South Korea and Japan — imported 1.64 million barrels per day (mbd) in January showing a rise of 67.6 percent from a year earlier, government and ship-tracking data showed, reported Reuters.
However that volume was the lowest in six months and marked a third straight month of decline from last year's peak of 1.99 mbd hit in October, according to data from the International Energy Agency.
Iran was exempted from an OPEC deal to reduce output by 1.2 mbd starting January 1, a victory for Tehran which has argued it needs to regain the market share it lost under Western sanctions over its nuclear program.
Japan's Trade Ministry on Tuesday released official data showing its imports rose 7.9 percent from a year earlier to 209,319 bpd in January.
India's imports more than tripled to 554,600 bpd, topping China's for the first time since November. South Korean imports more than doubled to 478,032 bpd, also beating China, to become the second-biggest buyer in Asia.
Iran's total crude and condensate exports for February to global markets, including Europe, will be just over 2.20 mbd, up from 2.16 million bpd last month, which is the lowest rate since July, an industry source familiar with the matter has said.
Looking ahead, Japan will likely skip Iran crude loading in March as buyers are waiting for the government to extend sovereign ship insurance in the new fiscal year that starts in April.
Iran has signed a flurry of deals with Western companies over the past year since the easing of international sanctions on Tehran after an accord was reached over its nuclear program.
Iran needs foreign investment for repairs and upgrading its oil and gas fields. It also seeks the transfer of technology to its oil industry after a decade of sanctions.
