China leads Aluminum supply with 13.5% of suppliers, followed by the United States ( 12.8% ) and the United Kingdom ( 10.5% ) — three major producing nations contributing to the global base of raw material availability.

8.7% of all listings were added in the last 30 days, indicating a steady but modest influx of new supply. 88.7% of suppliers remain active in the last 90 days, and 59.4% carry business verification — a reliable and largely reachable base with a significant portion having undergone documentation checks.
