Andy Home: Aluminium flow shifts after Trump doubles tariffs

In response to the increasing import tariffs, which first increased to 25% in march and then to 50 percent in June, Canadian aluminum smelters began diverting primary aluminium away from the United States.

Alcoa Corp., which has smelters both on the U.S. and Canadian sides, told analysts during its quarterly earnings call that it had sold more than 100,000 tons of Canadian steel to consumers outside the U.S. since March.

U.S. primary aluminum imports dropped dramatically in April and in May, even before U.S. president Donald Trump surprised the world with his second surprise tariff in June.

The import gap has been partially filled by the surge in shipments of recycled aluminium. This raw material, as a raw materials is only subject to Trump's lower tariffs.

The physical market dynamics will likely remain fluid, depending on both the U.S. premium as well as Trump's willingness and ability to grant exemptions.

PRIMARY INCOMES DOWN, SCRAP UPS

Imports of primary aluminum in the United States reached a two-year high, nearly 442,000 tons, in March. This was due to suppliers racing to meet the first deadline for tariffs.

The second rate hike was not anticipated and was implemented almost immediately, so there was no time to prepare for the new 50% rate. In fact, the 268,000 tons of imports in May were the lowest monthly total since December 2022.

The majority of the volume drop can be attributed to lower shipments from Canada. The biggest supplier of metal to the U.S. is redirecting the metal that has not been committed under annual contracts. In the case of Alcoa, this is about 30% of their Canadian production.

WBMS data shows that Canada exported 11,800 tonnes of aluminum to the Netherlands in March and 25,500 tonnes to Italy in April.

The imports of scrap aluminium are increasing, meanwhile, due to the difference between the reciprocal tariff and the aluminium one. Arrivals in March-May totaled 227,000 tons, an increase of 40% over the same period in 2024.

The European Commission activated its trade surveillance system before any possible export restrictions. The European Commission has promised to make a decision before the end of September.

MARKET WATCH

In response to the double tariff increase, the U.S. Midwest Premium has risen from 24 cents ($520 per ton in January) to 68 cents.

William Oplinger is the CEO and President of Alcoa. He says that this amount does not cover all the costs associated with tariffs on Canadian metal.

He said that the Midwest premium should be between 70-75 cents per lb when you take into account both the tariff and base costs of transportation to U.S. customers.

As buyers wait to find out if there will be any exemptions from the current blanket tariffs, they are reducing their inventory instead of making new purchases.

It is their right.

The Trump administration is reportedly considering lowering or eliminating aluminium tariffs on countries that sign up for broader trade agreements.

This included, for instance, a 25% reduction in import tariffs for both steel and aluminium products.

According to European Trade Commissar Maros Sfcovic, the newly-minted agreement with the European Union includes a potential carving-out for copper, aluminum, and steel.

He said that European and U.S. negotiators found a common cause, which is the overcapacity of China. For now, the higher tariff rate is still in place. However, both sides are working to create a "metals partnership" where tariffs would be replaced by a quota-based system.

Canada's importance in the U.S. aluminum supply makes it strange that Canada is not included in this alliance.

High SMELTER Restain Costs

One thing is certain, even though the tariff landscape is constantly changing. It will be a very long time before there is enough smelter capability in the U.S. to reduce its dependence on imports.

Two new smelter project are in competition with Big Tech to provide low-cost electricity. Even if the smelters can lock in their energy supply, it would take years to build.

According to the United States Geological Survey, there are also around 670,000 tonnes of idled smelting capacities in the U.S.

Many of the old machines need significant investment. Alcoa's Warrick smelter, in Indiana has a 50,000-ton per year line that is idle. It would cost around $100 million for refurbishment and another year to ramp up production.

Alcoa's Oplinger said that a decision to restart production would require "that the tariffs remain in place for a long time" before it could be justified.

Tariffs are likely to remain in some form, but the question of how many trading partners will be able to avoid paying the full tariff rate of 50% is becoming more and more open.

There won't be many U.S. Smelters restarted until the situation is clarified.

There will be more volatility in the supply chain.
