US alumina imports jump 32% in 2025 as Jamaica's exports double

In 2025, the US alumina story begins with rising imports, but it quickly reveals a system under strain. US alumina imports surged to 1.77 million tonnes in 2025, up 32 per cent from 1.34 million tonnes in 2024, reversing a marginal 1 per cent dip from 1.36 million tonnes in 2023. It reads like a rebound-but is it really a recovery story, or does it signal a deeper structural shift?

The movement through the year adds intrigue. Alumina imports rose consistently through the first three quarters of 2025 before reversing sharply in the final quarter. Volumes reached 439,000 tonnes in Q1, increasing to 466,000 tonnes in Q2, up 6 per cent quarter on quarter, and climbed further to 506,000
