U.S. President Donald Trump has imposed a 25% tariff on all steel and aluminum imports, marking one of the most discussed measures of his first month back in the White House.

But which countries are most affected by these tariffs?

This map illustrates the top suppliers of aluminum and steel to the United States in 2024. The data comes from the U.S. Census Bureau. Aluminum includes unwrought aluminum, plates, sheets, and strips; bars, rods, and profiles; foil; wire; pipes and tubes; castings and forgings; and tube or pipe fittings. 

Canada: The Largest Partner

Canada is by far the top supplier of both steel and aluminum to the United States. The neighboring country exported $9.4 billion worth of aluminum to the U.S. in 2024, significantly ahead of the second-largest exporter, the European Union, which exported $1.5 billion.

Canada also exported $7.1 billion worth of steel last year, compared to $7 billion from the European Union.

Mexico, South Korea, and Brazil are also among the top suppliers of steel to the United States. Meanwhile, the country imports aluminum from other key partners, including China, the United Arab Emirates, South Korea, Bahrain, and Argentina.

A recent report by the Center for Strategic and International Studies (CSIS) noted that the U.S. produces less than 2% of the world’s primary aluminum.
