From “Tariff Cuts” to “Tariff Hikes”: U.S.-Canada Steel and Aluminum Talks Take a Sudden Turn

From “Tariff Cuts” to “Tariff Hikes”: U.S.-Canada Steel and Aluminum Talks Take a Sudden Turn

A week ago, the market was still discussing whether U.S.-Canada tariffs on steel and aluminum might be reduced from 50% to 25%. Now, however, no agreement has been reached. Canada has instead announced retaliatory tariffs on more than 700 categories of U.S. goods, with tariffs on most U.S. steel and aluminum products set to rise from 25% to 50%. Expectations of easing trade tensions between the two countries are being replaced by a new round of tariff confrontation.

On August 25, the Canadian federal government announced retaliatory tariffs on more than 700 U.S. products worth C$27.6 billion, along with a C$7.5 billion support package for businesses and workers.

The retaliatory tariffs will take effect on September 8. They will be imposed at rates of 15%, 25%, and 50%, covering steel and aluminum, dairy products, household appliances, agricultural equipment, pulp and paper, plastics, electronics, and other sectors.

For the aluminum industry, the most important point is that tariffs on most steel and aluminum products imported from the United States will increase from 25% to 50%. Some steel and aluminum derivative products will be subject to a 25% tariff.

This means that trade frictions between the United States and Canada over steel and aluminum products have not eased despite earlier market speculation about negotiations. Instead, they have escalated further.

Previously, the two countries appeared close to reaching a new trade arrangement, and there were reports that the United States might reduce tariffs on some Canadian steel and aluminum products. However, the latest developments show that no final agreement was reached. After Canada suspended trade talks on August 22, it decided to implement equivalent retaliatory measures.

Based on currently available information, one key principle behind Canada’s measures is “equal and reciprocal” retaliation. Canada has stated that the value of U.S. goods covered by its tariff list is equivalent to the value of Canadian goods affected by the United States’ 50% tariffs.

Why has Canada raised tariffs on U.S. steel and aluminum products to 50%?

The reason is relatively straightforward. Steel and aluminum products are an important part of U.S.-Canada trade and are among the sectors with the closest links between the two countries’ manufacturing industries and supply chains. Higher tariffs will increase the cost of U.S. steel and aluminum products entering the Canadian market. Canada hopes to use this measure to pressure the United States while creating more market space for domestic companies.

For Canadian steel and aluminum producers, higher prices for imported U.S. products could, in theory, reduce competition from lower-priced imports. However, the situation is not entirely favorable for downstream manufacturers in Canada.

Automotive components, construction, machinery, household appliances, and packaging industries all require steel and aluminum materials. If companies still need to purchase U.S.-origin steel, aluminum, or related components, their costs may also rise. Eventually, part of these additional costs could be passed on to end-product prices.

U.S. companies will also be affected. Canada is an important export market for the United States, and U.S. steel and aluminum producers, appliance manufacturers, agricultural equipment suppliers, and pulp and paper companies may face reduced orders or higher export costs.

Will this tariff escalation immediately drive up global aluminum prices?

In the short term, the impact is more likely to appear first in the North American market.

As tariffs rise, trade flows involving U.S. aluminum, Canadian aluminum, and aluminum products from other regions may shift. Products that previously moved freely within North America may need to find new sales markets or new sources of supply. North American spot aluminum prices, regional premiums, and quotations for certain aluminum products may therefore fluctuate.

However, U.S.-Canada tariffs are not the only factors affecting LME aluminum prices or SHFE aluminum prices. LME inventories, global supply and demand, Middle East capacity recovery, energy costs, and manufacturing demand remain the main variables influencing international aluminum prices.
