United States implements aluminum tariffs and subsidies to boost domestic manufacturing

The United States is implementing significant trade policies aimed at revitalizing domestic aluminum production, including a 50% tariff on Canadian aluminum imports. This move seeks to reduce reliance on foreign supplies, particularly from Canada, which provides more than half of American aluminum imports used in the automotive, military, and robotics sectors.

To support this industrial shift, the federal government is providing incentives for new capacity, such as a proposed $4 billion smelter in Oklahoma backed by Emirates Global Aluminium and Century Aluminum. The administration is also utilizing the Defense Production Act to guarantee demand for high-purity aluminum required for missiles, drones, and airframes, as the Pentagon anticipates a 188% increase in missile procurement.

However, analysts note several challenges to this strategy. Domestic production faces high electricity costs and an aging power grid. Furthermore, the current price spread between global and domestic aluminum is driven by political tariffs, creating uncertainty for long-term industrial investments if trade policies shift with future administrations.
