United States President Donald Trump has announced plans to impose 25 percent tariffs on all steel and aluminium imports, and reciprocal tariffs on countries levelling duties on US goods.
On Monday, during a signing ceremony at the Oval Office, Trump announced the tariffs on foreign steel and aluminium were to be imposed “without exceptions or exemptions”.
The tariffs are set to come into effect on March 12.
Who are the top suppliers of steel to the US?
Steel is an important material primarily used in construction, manufacturing, transportation and energy sectors due to its strength, durability and versatility.
Roughly a quarter of all steel used in the United States is imported.
Canada, Brazil and Mexico are the top three suppliers of steel to the United States. Between March 2024 and January 2025, they provided about half (49 percent) of steel imports for domestic consumption, according to the International Trade Administration.During that period, Canada supplied 22 percent (5.47 million tonnes) of the 25 million tonnes of steel imported into the United States, followed by Brazil with 15 percent (3.74 million tonnes) and Mexico with 12 percent (2.9 million tonnes).
