Japan's crude oil imports from Iran in February fell 32.3 percent from a year earlier to 953,848 kilolitres (214,268 barrels per day), the Ministry of Economy, Trade and Industry (METI) data showed on Friday, as the world's third-biggest oil consumer seeks a waiver from U.S. sanctions, Reuters reported.
Japan's Ministry of Finance recently issued customs-cleared imports data from Iran, but the oil industry considers METI data as a benchmark because it tracks the actual import status of oil tankers.
Imports by Japan, Iran's No.3 crude buyer, are expected to continue declining this year after dropping 39.5 percent last year as the United States and the European Union ratchet up sanctions targeting Iran's disputed nuclear programme.
Under pressure from sanctions, Iran's overall oil exports more than halved last year, costing it over $5 billion a month. Tehran says its nuclear programme is for civilian purposes, while the West accuses it of aiming to develop nuclear weapons.
Japan's February crude imports from Iran were 953,848 kilolitres (214,268 barrels per day), down 32.3 percent from a year ago and 19.1 percent lower than in January, data from the Ministry of Economy, Trade and Industry (METI) showed.
For the first two months of 2013, Japan imported 2,132,205 kl (227,308 bpd) of Iranian crude, down 30.8 percent from the same period a year ago.
The figures contrast with customs-cleared data on Thursday which showed Japan's Iranian crude imports rose 15.9 percent in February to the highest in eleven months, but the industry considers the trade ministry data a benchmark because it tracks the actual import status of oil tankers.
The International Energy Agency said in its March report that new U.S. sanctions on Iran implemented in February, which barred the country from repatriating oil export earnings, appeared to have not had an impact on February shipments.
Iranian crude oil exports were expected to hold strong and even exceed 1.4 million bpd in March from 1.28 million bpd in February, said the IEA, which coordinates the energy policies of major consuming nations.
The report was at odds with industry expectations that the new U.S. measures would push Iran's exports in March to their lowest since Western sanctions came into effect in 2012.
Earlier this month, the United States extended 180-day waivers on Iranian sanctions to Japan and 10 European Union nations in exchange for their cutting purchases of the OPEC nation's crude oil.
Most other major Asian buyers of Iranian crude also cut imports last month, although China, Iran's top crude oil customer, was an exception and imported 521,330 bpd, up 81 percent on the year.
India reduced oil imports from Iran by 43 percent to 259,000 bpd from a year ago, as New Delhi struggled with new insurance issues that may trigger more cutbacks in shipments from Iran.
South Korea imported 141,929 bpd from Iran in February, down 30 percent on year, and its imports could plunge even further in March given a heavy refinery maintenance schedule.
The United States in February imposed new sanctions against Iran, aiming to trap its oil revenues so they are locked up in a purchasing country and used solely for buying goods from that country.
