Iran is planning to sell 300,000 barrels per day (bpd) of crude oil into Europe following the removal of western sanctions.
The volumes, equal to a suezmax cargo nearly every three days, were revealed by the state-run oil news agency Shana, citing oil minister Bijan Zangeneh.
Overall, Iran is trying to boost oil exports by 500,000 bpd, with Asia taking most of the rest.
