The trade penalties, 25% on imported steel and 10% on imported aluminum, take effect at midnight, Commerce Secretary Wilbur Ross told reporters Thursday. Mexico, the EU and Canada immediately announced plans to retaliate with their own tariffs against American products. Trump announced worldwide steel and aluminum tariffs in March but granted exemptions to some major trading partners.
Canada, Mexico and the EU were among the countries granted relief while the United States pursued negotiations to address the administration’s concerns about the state of domestic steel and aluminum production. Those negotiations had a Friday deadline.
