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.

This graphic breaks down the market value of the entire global mining industry, as of Jan. 16, 2025, using data from Companiesmarketcap.com.

Note that this data only covers publicly-traded companies.

Australia and Canada Lead

Australia tops the list, with its major mining companies totaling $353 billion in market capitalization. The country is home to two of the biggest miners in the world, BHP and Rio Tinto.

Rich in minerals, Australia is the world’s largest producer of iron ore, essential for steel production, and lithium, a key component in batteries.

While Canada’s economy has struggled to keep pace with its southern neighbor, its mining industry remains formidable.

The country’s mining sector has a combined market capitalization of $344 billion, making it the second-largest globally.

Canada, the world’s second-largest country by area after Russia, has vast natural resource wealth. It is particularly rich in gold, copper, nickel, and potash.

United States with miners totaling $228 billion and China with companies totaling $206 billion come in third and forth, respectively.
