Tariffs, tensions and tonnage: Three words primarily influencing US aluminium prices soar in 2025

In a volatile fusion of tariff tensions, supply chain snarls, and shifting trade dynamics, US aluminium import costs have surged to multi-year highs, reshaping the metals market and sending shockwaves through American manufacturing.
On April 9, 2025, the United States imposed additional aluminium tariffs — 20 per cent on EU-origin goods and 10 per cent on UK imports, building on the existing 25 per cent base duty introduced under Section 232 in 2018. For EU producers, the effective tariff rate now stands at a crushing 45 per cent, sending shippers and buyers scrambling.
The Midwest Premium, the benchmark regional surcharge that includes transport, handling, and tariffs, has reacted dramatically. According to Reuters and CME Group data, the Midwest Premium recently spiked to over 33 cents per pound, a level not seen since the tariff war era of 2018-2019. That’s nearly double the average of 17-18 cents recorded in early 2023.
