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.

Charted: If Gold Was Shared Equally, How Much Would You Get?

Desired for millennia because of its shine and rarity, gold is still the safe haven asset (with fairly decent returns) in times of uncertainty.

This chart examines a hypothetical question of how much gold every person in the world would get if all discovered gold was shared equally.

Data for this graphic is sourced from the U.S. Geological Survey and from the UN’s World Population Prospects 2024.

There’s Not a Lot of Gold for 8 Billion People

Turns out, there really isn’t a lot of gold in the world.

To date, only 244,000 metric tons of gold have ever been discovered. This includes historical production and current known discoveries.

That works out to about 30 grams (about one troy ounce), or six gold rings, for every single human being on the planet.

Of course, jewelry isn’t the only use of gold (though it does account for the largest share of above-ground use).

Central banks have quite a bit in their reserves, with the U.S. holding the most at roughly 8,000 tonnes.

At sixth place China (2,200 tonnes) has been steadily increasing its reserves in the past year, in a bid to diversify foreign exchange reserves away from the U.S. Treasury bonds.

Largest Gold Producers

And then there’s all the gold beneath the ground, spread out in massive mines across the world. Of them, Australia is home to two in the top 10, and is also the second-largest producer.

Who’s the largest producer? That’s China—even though it doesn’t have any large mines on the same scale as those found in the U.S. and Australia. Instead it has numerous smaller ones, and coupled with efficient smelting infrastructure, ends up producing more volume.

Finally, South Africa held the top supplier spot between 1900–1970. Its production peaked at about 1,000 tonnes annually, the most by any country in a single year.
