US to double tariffs on steel and aluminium imports to 50%, Trump says15 hours ago Share Save Brandon Drenon and Natalie Sherman BBC News Share SaveWatch: Trump announces 50% tariff on steel and aluminiumPresident Donald Trump has announced the US will double its current tariff rate on steel and aluminium imports from 25% to 50%, starting on Wednesday.

He recalled "making a lot of money" in the years after Trump instituted steel tariffs in his first term.
