BRUSSELS (Reuters) - The European Union is set to impose provisional duties on Chinese biodiesel after finding it is being sold in EU markets at unfairly low prices.

The European Commission, which oversees EU trade policy, has indicated it will set tariffs of between 12.8 and 36.4%, according to a document published on Friday. They are due to be imposed in mid-August.

The investigation is due to continue until February, when definitive duties for five years could be set.
