Summary
Alcoa, the largest U.S. aluminum producer, revealed a $69 million increase in costs due to tariffs on Canadian aluminum during Q3 2025. However, rising U.S. aluminum prices, driven by reduced imports and inventory, have offset these costs. Aluminum premiums in the Midwest have surged 113% since June. Despite this, Alcoa anticipates an additional $50 million in tariff costs next quarter. The tariffs, introduced by former President Trump in March 2025 and doubled in June, aim to protect U.S. industries and boost domestic production. Alcoa has resumed normal aluminum shipments from Canada to the U.S., reflecting market adjustments.
