Harbor Aluminum Predicts Growth Potential in Soaring Midwest Premium

Aluminum Tariffs Drive Midwest Premium Surge

Aluminum market watchers, including consulting firm Harbor Aluminum, see more upside ahead for the Midwest premium, which recently surged to 62.5 cents per pound. This jump follows President Donald Trump’s announcement of a 50 percent Section 232 tariff on aluminum imports.

According to a Reuters analysis, producers like Matalco and Century Aluminum stand to benefit. Matalco, partially owned by Rio Tinto, uses recycled-content aluminum and avoids the new tariff by relying on untaxed aluminum scrap. As a result, U.S.-based operations gain access to lower-cost feedstock while benefiting from higher selling prices.

In addition, scrap aluminum imports into the United States rose over 30 percent in Q1 2025, signaling that recyclers are acting fast to meet demand. Trade Data Monitor confirms a total of 201,968 tons of scrap imported, compared to the same period in 2024.

Midwest Premium Could Climb Higher Despite Demand Risks

Harbor Aluminum says the Midwest premium must rise to 70 cents per pound—$1,543 per ton—to fully reflect tariff costs. If realized, that would further boost margins for domestic recyclers and smelters using untaxed scrap inputs.

However, industry insiders warn of potential downsides. Reuters quotes sources concerned that excessive price increases could dampen downstream demand. The current premium already gives U.S. recyclers a bidding edge, letting them outpay international competitors for scrap.

Meanwhile, in contrast, Europe’s aluminum premium has dropped over 50 percent since January to $170 per ton. Analysts expect some producers to divert primary aluminum from the U.S. to European buyers to sidestep tariffs, which may shift market dynamics globally.

SuperMetalPrice Commentary:

The Midwest premium surge reflects a dramatic shift in U.S. aluminum pricing fundamentals driven by aggressive trade policy. While companies like Matalco and Century Aluminum may enjoy short-term gains, the broader market remains exposed to demand destruction and global supply shifts. Harbor Aluminum’s view that the premium has more room to rise is plausible—but it comes with volatility risk. Watch closely as scrap flows, trade barriers, and price differentials reshape global aluminum trade in real time.
