Century Aluminum Co. has commenced metal production from its expanded South Carolina smelter facility, marking a rare increase in domestic aluminum output. The expansion represents a notable development for a sector that has seen limited domestic production growth in recent years. This new capacity comes at a time when US manufacturers seek more localized supply chains.

The South Carolina facility's expansion delivers approximately a 10% lift to Century Aluminum's total US production capacity. This increase arrives amid ongoing discussions about industrial policy and domestic manufacturing capabilities. The timing suggests the company anticipates sustained demand for primary aluminum in North American markets.

Century Aluminum joins a small number of US producers expanding capacity while global aluminum markets face volatility. The company's investment in its South Carolina operations signals confidence in long-term domestic demand. Market watchers will monitor whether other US producers follow similar expansion strategies to capitalize on this rare production growth in the US aluminum sector.
