The Trump administration is expected to hit the European Union with steep tariffs on steel and aluminum, The Wall Street Journal reported on Wednesday.

EU trade officials have spent the past couple of months trying to work out an agreement to stave off the tariffs and earn the 28-nation bloc an exemption.

But those efforts appear to have failed with the U.S. planning to slap the hefty tariffs on a key ally.

The White House extended until Friday the deadline for several nations, including the EU, Argentina and Brazil, to reach deals on their steel and aluminum imports before getting hit by the tariffs.

"There can be negotiations with or without tariffs, it’s not that you can’t talk with tariffs,” Ross said, the Financial Times reported.

“China is an interesting case in point. They are paying the tariffs; they came into effect in March and they haven't used this as an excuse not to talk. It’s only the EU insisting we can’t negotiate if there are tariffs."

French President Emmanuel Macron and German Chancellor Angela Merkel each lobbied Trump for a waiver during recent trips to the White House.

If Trump moves forward, the EU will likely retaliate next month with promised tariffs of about $3.3 billion on iconic American products such as bourbon, jeans and motorcycles.

An announcement from the White House could come as early as Thursday, the Journal said.

Earlier in the day, the American Chamber of Commerce in the EU called on Trump to provide a permanent exemption from any metals tariffs because of the economic importance of the relationship.

“The EU is America’s staunchest ally, not a U.S. national security threat,” the Chamber said on Twitter.
