President Donald Trump signed an order Monday imposing global tariffs of 25% on all steel and aluminum imports, likely pleasing domestic steelmakers but hurting allies like Canada and Mexico.

U.S. President Donald Trump signed proclamations late on Monday to raise tariffs on all steel and aluminium imports to 25% without exceptions or exemptions. A White House official confirmed that the measures would take effect on March 4.

French steelmaker Aperam on Tuesday called on Brussels to intervene to curb imports if new 25% tariffs on all steel and aluminium imports into the United States prompt companies to ship more to the European Union instead.
