BRUSSELS, Feb 10 (Reuters) - The European Commission

said on Monday it would react to protect EU interests after U.S.

President Donald Trump's announcement of impending metals

tariffs, but said it would not respond until it had

clarification of the measures.

Trump said on Sunday that he would introduce new 25% tariffs

on all steel and aluminium imports into the United States, in

another major escalation of his trade policy overhaul.

The Commission said it had not received any official

notification regarding additional tariffs on EU goods and would

not respond to "broad announcements" without details or written

clarification.

"The EU sees no justification for the imposition of tariffs

on its exports. We will react to protect the interests of

European businesses, workers and consumers from unjustified

measures," the Commission said in a statement.

Trump's move, if confirmed, would mirror his action in his

first term, when he imposed 25% tariffs on steel from many

countries and 10% tariffs on aluminium. For the EU that covered

6.4 billion euros ($6.6 billion) worth of exports.

The EU responded in 2018 with an initial set of tariffs

on 2.8 billion euros worth of U.S. goods, including bourbon and

Harley Davidson ( HOG ) motorcycles. It planned to add a further 3.6

billion euros of U.S. goods after three years.

By then, Joe Biden was U.S. president and the two sides

agreed to suspend U.S. tariffs and EU countermeasures, the

former until the end of this year, the latter until March 31.

The United States' suspension of tariffs amounted to a

quota of 3.3 million metric tons of steel and 384,000 tonnes of

aluminium from EU producers, based on historical averages.

EU diplomats said it would make most sense to reapply

the countermeasures if Trump went ahead with the import tariffs.
