By mid-2019, the tariffs were lifted for Canadian and Mexican imports, which accounted for 27% of the U.S.’s steel imports and 43% of its aluminum imports. The Biden administration later ended tariffs on European Union metals in 2021, amid record-high steel prices fueled by COVID-19 supply chain disruptions.

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 Donald Trump officially increased tariffs on all steel and aluminum imports to 25% on Wednesday, promising that the taxes would help create U.S. factory jobs at a time when his seesawing tariff threats are jolting the stock market and raising fears of an economic slowdown.
