    Citing Benefits of 232 Tariffs, Century Aluminum Announces Restart to Bring Mt. Holly SC Plant to Full Production, Increasing U.S. Aluminum Production by 10%

    CHICAGO, Aug. 07, 2025 (GLOBE NEWSWIRE) -- Century Aluminum Company (NASDAQ:CENX) has announced plans to restart over 50,000MT of idled production at its Mt. Holly, SC smelter. Century will invest approximately $50 million in the effort, create over 100 new jobs and boost U.S. domestic aluminum production by almost 10 percent. The restart will enable the plant, currently operating at 75 percent capacity, to achieve full production by June 30, 2026, a level not seen since 2015. The restart comes as a direct result of President Trump's application of Section 232 tariffs for primary aluminum, most recently increasing the tariffs to 50% on aluminum imports without exceptions or exemptions.
