European Trade Commissioner Cecilia Malmstrom said on Thursday it was still unclear what Washington wants in return for a permanent EU exemption from steel tariffs. “We are still in doubt,” Reuters quoted the official as saying during a visit in Copenhagen. US President Donald Trump has given the EU and six countries until May 1 to negotiate permanent exemptions from tariffs of 25 percent on steel and 10 percent on aluminum. According to Malmstrom, she had not received any new deadline but holds “regular discussions” with US Commerce Secretary Wilbur Ross on the issue.
