LONDON/FRANKFURT, March 29 (Reuters) - The European Commission has decided against imposing duties on hot-rolled steel from Brazil, Iran, Russia, Serbia and Ukraine for now, but could still find they have breached rules on unfair competition, two industry sources said on Wednesday.

The European Commission had no immediate comment.

The EU executive has a deadline of April 7 to announce whether it is imposing provisional duties on the steel after complaints it is being sold into Europe at unfairly low prices that make it hard for EU manufacturers to compete.

The sources, speaking on condition of anonymity, said the Commission had decided against provisional duties, but that is only one step.
