Trump's action to bulk up protections for American steel and aluminum producers restores effective global tariffs of 25% on all imports of the metals.

President Trump imposed a 25 percent tariff on metal imports. The move is expected to raise costs for U.S. manufacturers of cars, solar panels and other products, potentially slowing the economy.

Australian Prime Minister Anthony Albanese says U.S. tariffs on Australian steel and aluminum are unjustified, but his government will not retaliate with its own tariffs.
