Aluminum premiums for US buyers rise after Trump doubles tariffs

The price of aluminium in the United States has risen dramatically since Donald Trump announced that he would increase the tariffs from 25% to 50% on imports of steel and aluminum.

The U.S. heavily relies on imports of aluminium. Around half of the aluminium used for transportation, packaging, and construction in the U.S. is imported, the majority from Canada. The new tariffs will be in effect from June 4.

On the physical market, buyers pay the London Metal Exchange benchmark price for aluminium plus a premium to cover taxes, transportation and handling costs.

On Monday, the duty-paid aluminum premium in the Midwest of the United States reached $0.58 a lb or $1,279 per metric ton. This was a 54% increase from Friday, and a 164% growth rate since 2025.

The fact that Monday was the first trading day in a new month, which is when regional premiums are often at their strongest, contributed to the growth.

Goldman Sachs estimated that the premium needed to increase to $0.68 to $0.70 per lb in order to reflect the import tariff of 50%. LME benchmark aluminum was last up by 0.2%, at $2448.5 per ton. (Reporting and editing by David Goodman.
