US alumina imports surge as domestic output falters — a sign of growing reliance?

While bauxite imports to the United States show a steady course, alumina tells a different story. In the first quarter of 2025, US alumina imports reached 439,000 tonnes, marking a significant uptick both year-on-year and quarter-on-quarter. The data revealed a 24.7 per cent rise from the previous quarter (352,000 tonnes) and an even sharper 53.5 per cent leap compared to Q1 2024 (286,000 tonnes), signaling a marked shift in sourcing dynamics.
The upward trajectory, which began in Q2 2024 with 325,000 tonnes, gained momentum through Q3 (378,000 tonnes), momentarily slowed in Q4 (352,000 tonnes), and rebounded strongly in Q1 2025. This pattern, when juxtaposed with falling domestic production, paints a clear picture: the US is becoming increasingly dependent on imported alumina.
