Canada supplies roughly 60% to 70% of the imports that come into the U.S. market. Canadian suppliers like Rio Tinto produce high quality aluminum that is typically sold to stateside buyers.

Metallus praised Trump's recent 25% tariff on steel and aluminum. Regional manufacturers say their operations shouldn't be majorly impacted.

“Any steel coming into the United States is going to have a 25% tariff,” he told reporters Sunday on Air Force One as he flew from Florida to New Orleans to attend the Super Bowl. When asked about aluminum, he responded, “aluminum, too” will be subject to the trade penalties.

U.S. tariffs could cause the prices of steel and aluminum cans to rise, an increase that may ultimately be passed on to consumers.
