[U.S. Aluminum Prices Rise 40% Due to Tariffs and Low Inventory] The price of aluminum products in the U.S. has continued to soar due to global supply constraints, the impact of tariffs, and insufficient domestic inventory. In June last year, Trump raised import tariffs on aluminum products to 50%, leading to a 40% increase in U.S. aluminum prices, surpassing $5,200 per ton. Over the past 12 months, LME aluminum prices have risen more than 20%, reaching a post-Russia-Ukraine conflict high. This week, the U.S. Midwest aluminum premium over LME prices reached 96 cents per pound ($2,116 per ton), up approximately 65% since June last year. U.S. aluminum inventory has dropped from 750,000 tons at the beginning of 2025 to less than 300,000 tons.
