Alumina exports totaled 374,266 tonnes in Q3 2025, falling 5.3% from the previous quarter but remaining 12.9% higher year-on-year, reflecting mixed performance across operating refineries. Windalco shipped 98,548 tonnes of alumina, an 11.9% quarterly decline and 9.4% below Q3 2024, reversing part of its strong Q2 rebound. Jamalco accounted for the majority of exports at 275,718 tonnes, down 2.7% quarter-on-quarter but up 23.9% year-on-year, supported by improved output as shipments were severely constrained during this period in 2024 due to Hurricane Beryl’s damage to the refinery’s port facility.

Year-to-date export volumes reached approximately 1.13 million tonnes, a 1.4% increase over the same period in 2024, as Jamalco’s strong year-on-year gains outweighed Windalco’s Q3 slowdown
