Trump tariffs of 25% on steel and aluminium come into effect globally as Europe says it will retaliate
March 18
On March 18, the U.S. officially imposed 25% tariffs on all global imports of steel and aluminum. The European Union promptly announced retaliatory tariffs worth €26 billion targeting U.S. industries, while Canada introduced equivalent 25% duties on nearly $30 billion of U.S. exports. The escalation generated widespread concern about disrupted supply chains and potential job losses.
