Canada Tariffs Deepen North America’s Steel and Aluminum Squeeze

The renewed trade war between the United States and Canada has introduced additional uncertainty to the intricate steel and aluminum supply chains that are vital for heavy manufacturing and the North American automotive industry. After last week's collapse in trade talks, tariffs and counter-tariffs were quickly imposed on each other's imports.

This escalation in the trade war will affect key metals, such as steel and aluminum, forcing producers and importers to find longer-term solutions to the heightened uncertainty surrounding material supply costs. It is uncertain which party will benefit from this trade escalation, as supply chains are so intertwined that businesses on either side of the U.S.-Canada border may have to pay tariffs multiple times.

Both nations have announced tariffs on $20 billion worth of each other's goods, including alcohol, hockey sticks, cement, machinery, steel, aluminum, dairy, appliances, agricultural equipment, pulp and paper, and electronics. Canada's government vowed to match the U.S. tariffs, which were effective August 22 dollar for dollar. The re-escalation in the trade war is causing businesses to scramble to reassess their supply chains and identify which items will be impacted by the new tariffs.

While the U.S. steel sector may have a slight advantage over Canada, the complex automotive sector, with its multiple cross-border materials and parts shipments, will suffer losses on both sides of the border. Both analysts agree that there will be no clear winners in this trade escalation, as the uncertainty surrounding material costs will persist for some time.

The U.S. steel market is larger than Canada's, giving the U.S. a small edge in the steel industry. However, the aluminum industry poses a significant challenge for the U.S., as Canada currently supplies 60% of all unwrought aluminum imports in the U.S. Without new capacity, which takes years to build and ramp up, the U.S. will continue to rely on higher-cost imports.

The AI boom could further complicate the aluminum buildout, as data centers require aluminum in power cables, cooling systems, server racks, and buildings, and these materials also compete with smelters for electricity supply.
