Gibbsite Aluminum Hydroxide (Bayer Process)
Crystalline gibbsite form of aluminum hydroxide produced via the Bayer process from bauxite ore for alumina production. Classified under HTS 2818.30.00.00 as pure aluminum hydroxide mineral. Used primarily in aluminum smelting feedstock.
Import Duty Rates by Country of Origin
Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If containing >20% mineral impurities from ore
Impure bauxite-derived products classify as mineral substances rather than pure chemical compounds.
If partially calcined to aluminum oxide hydrate
Thermal processing changes composition to aluminum oxide, moving to preceding subheading.
If for raw bauxite containing aluminum hydroxide
Natural ore mixtures fall under aluminum ores, not refined chemical compounds.

Import Tips & Compliance
• Provide mineral assay reports confirming >95% Al(OH)3 content to distinguish from bauxite residues
• Declare intended use as alumina feedstock to prevent scrutiny under anti-dumping measures on alumina
