Copper is the third-most-used metal in the United States, behind iron and aluminum, and imports make up 45% of refined copper consumption. This makes the metal and industries that rely on it susceptible to tariffs and other trade disruptions. Imports of semi-finished copper and "copper-intensive derivative products" will face a 50% tariff starting on August 1.

The Motley Fool has compiled data on copper imports to guide investors through potential trade volatility as the Trump administration considers tariffs on the metal.

Where does the U.S. import copper from?

Refined copper accounts for the majority of U.S. copper imports from Chile.
Canada exports a combination of refined copper, copper wire, and scrap to the United States.
Mexico’s largest copper export to the United States is copper scrap.
Peru and Congo mainly export refined copper to the United States.

Refined copper is used in electrical wiring, plumbing, and electronics. Copper wire is mainly used in power transmission, generation, and telecommunications. Copper scrap is recycled to manufacture new copper products.

How much copper does the U.S. produce?

The United States mined 1.1 million metric tons of copper in 2024 and refined 890,000 metric tons of copper. It has 47 million metric tons of copper in reserve.

Chile was the largest miner of copper in 2024, producing 5.3 million metric tons. It refined 1.9 million metric tons.

China was the largest copper refiner in 2024, pumping out 12 million metric tons of refined copper. Congo was the second-largest copper refiner that year by a wide margin, producing 2.5 million metric tons.

What investors should know about copper tariffs

Imports of semi-refined and and "copper-intensive derivative products" will face a 50% tariff starting on August 1. Those tariffs are a result of a Section 232 investigation which found that copper imports pose a threat to national security. The tariffs will not stack with other Section 232 tariffs, such as those on automobiles and auto parts.

Tariffs, if applied to countries that are top exporters of copper to the United States, could disrupt commodity prices and market performance of companies in sectors that heavily rely on copper, including construction, utilities, telecommunications, and electronics manufacturing. Tariffs could also result in countermeasures from major exporters, such as Chile, Canada, and Mexico.

Investors should stay informed about the latest policy developments and market reactions to potential copper tariffs.
