Aluminum premiums for US customers hit record high after Trump doubles tariffs

The premiums that consumers pay for aluminium purchased on the physical market of the United States reached record levels on Tuesday, after President Donald Trump announced he would double the tariffs to 50% on Canadian metal.

As a result of Ontario, Canada, imposing a 25% tariff, the doubling of the levies will take effect on Wednesday.

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

The traders predict that premiums will rise in the future as producers try to pass on as many of the additional costs associated with tariffs as possible.

Most of the primary and alloyed aluminum shipped to America comes from Canadian smelters. Aluminium is essential for transport, packaging, and construction industries.

Trade Data Monitor (TDM) reports that about 70% of the aluminium alloys and primary exported to the United States in the past year came from Canada.

Analysts calculated that the 25% tariff would have required a premium of 47 cents per lb, or more than $1000 a ton, to cover extra costs to sellers.

The U.S. Midwest duty paid aluminium premium increased to 45 U.S. Cents per lb or more than $900 a metric tonne on Tuesday. This is a nearly 20% increase from Monday. The price has increased by more than 70% from the beginning of 2025.

Trump, during his former presidency in 2018, sought to use aluminium tariffs to encourage investment.

Analysts were skeptical that investors would spend large sums of capital to build aluminium smelters, given the fact that they take longer to construct than political elections cycles.

Macquarie analysts wrote in a report last month that "U.S. Primary Aluminium Production has seen a sequential drop over the past 20 years due to thin or negative margins. The implementation of tariffs has not helped the local supply recover sustainably."

Sources in the industry say that while premiums have increased for U.S. consumers, they will likely continue to fall elsewhere due to aluminium being diverted from countries with import taxes.

In Europe, duty-paid physical premiums have dropped to $240 per metric ton. This is the lowest level since January of last year. Since the beginning of 2025, it has dropped by more than 35 percent. Reporting by Pratima Dasai Editing and reporting by Eric Onstad David Goodall, Barbara Lewis
