China nominates full contract amount of Iran oil in Aug -sources

in Aug

BEIJING, Aug 7 (Reuters) - China, Iran's top oil customer

and trading partner, has nominated full contract volumes of

Iranian crude for loading this month, steady with July, trade

sources said, after imports from the Middle Eastern country hit

an ll-month high in June.

China is expected to load just over 16 million barrels of

Iranian oil in August, the second month that it is using the

vessels of National Iranian Tanker Co. (NITC) to deliver oil to

its ports to get around a European Union insurance ban.

Iran's oil exports halved in the four months from February

to June because of sanctions aimed at choking off oil revenue

and forcing Tehran to curb its nuclear programme, which the West

believes is aimed at developing weapons, a motive Iran denies.

"The volume for August has been confirmed," said a

Beijing-based oil official with direct knowledge of the matter.

"For the rest of the year, the volumes should be largely

steady each month. We are not expecting big fluctuations," said

a second official.

Both declined to be named because company policy forbids it.

China, Iran's biggest trading partner, in July loaded a

similar amount of Iranian oil, or roughly 520,000 barrels per

day (bpd), a level at which China would account for around half

of Iran's total July exports of about 1.1 million bpd.

The full contractual volume of July loadings followed

surprisingly high imports in June, which were the highest in

nearly a year as reported by Chinese customs. Some traders

believed it was a one-off skewing in the data tally, while

others suspected China might have taken in extra bargain

oil.

The EU sanctions that took effect on July 1 forced China to

ask NITC to deliver crude, as Chinese vessels can no longer buy

cover from the European insurers who dominate the sector.

Chinese firms would still need to negotiate with NITC the

freight cost for each vessel for August loadings as the cost of

each ship varies. But both sides expected the talks to be

smoother than in July, when a freight dispute briefly threatened

to delay the shipments.

"So far two vessels have already been loaded," said the

first official.
