Products classified under HTS 2606.00.00
Bauxite Ore
Bauxite is the principal ore of aluminum, primarily composed of alumina minerals such as gibbsite, boehmite, and diaspore, often found mixed with iron oxides and silica. It falls under HTS 2606.00.00 as a raw aluminum ore extracted from surface deposits and used directly for aluminum production via the Bayer process. This classification covers unprocessed or minimally processed aluminum-bearing ores.
Gibbsite Bauxite Concentrate
Gibbsite bauxite concentrate is a refined form of bauxite ore rich in gibbsite (Al(OH)3), separated through washing and screening to increase aluminum content. Classified under HTS 2606.00.00 as an aluminum ore concentrate suitable for alumina refining. It retains its natural ore characteristics without chemical processing.
Boehmite-Rich Aluminum Ore
Boehmite-rich aluminum ore consists of bauxite deposits high in boehmite (γ-AlO(OH)), often from lateritic soils, used in aluminum extraction. It is classified under HTS 2606.00.00 for all aluminum ores and concentrates regardless of specific mineralogy. This ore requires higher-temperature digestion in refining.
High-Grade Bauxite Lump Ore
High-grade bauxite lump ore features large particles (>6.3mm) with 45-50% alumina content, minimally crushed for transport. Falls under HTS 2606.00.00 as unprocessed aluminum ore ideal for direct feed into alumina plants. Lumps reduce dust issues in shipping.
Washed Bauxite Ore Fines
Washed bauxite ore fines are <6.3mm particles cleaned of clay and silica through wet processing, concentrating aluminum minerals. Classified in HTS 2606.00.00 as ore concentrates prepared for Bayer process without smelting. Fines offer higher recovery rates.
Guinea Bauxite Ore
Guinea bauxite ore from West African deposits typically contains 40-50% alumina with low reactive silica, shipped in bulk for global refineries. It is classified under HTS 2606.00.00 as standard aluminum ore. Known for its high grade and large-scale mining operations.
Australian Calcined Bauxite Residue
Australian calcined bauxite residue is thermal-activated ore waste from refining, still containing recoverable aluminum. However, as raw ore material, it falls under HTS 2606.00.00 if not fully processed. Used in secondary recovery operations.
