HS Code for Alumina

Alumina, or aluminium oxide, is classified under HS code 2818.20. This classification falls within Chapter 28 (Inorganic Chemicals). Heading 2818 specifically covers artificial corundum, aluminium oxide, and aluminium hydroxide. The subheading 2818.20 is designated for aluminium oxide other than artificial corundum. This classification is determined by the chemical purity and physical state of the material. Alumina is typically produced from bauxite through the Bayer process and serves as the primary feedstock for aluminium metal production, as well as an abrasive and refractory material. To qualify for 2818.20, the substance must be a chemically defined aluminium oxide that has not been fused into artificial corundum, which is a distinct crystalline form classified elsewhere.

Products Included

• Calcined alumina
• Activated alumina (used as a desiccant or catalyst support)
• Metallurgical grade alumina
• Tabular alumina (non-fused)
• Hydrated alumina (when classified as an oxide)

Common Misclassification

Alumina is frequently confused with 2818.10, which is the code for artificial corundum (fused alumina). The difference is that 2818.10 involves alumina that has been fused in an electric furnace. It is also sometimes misclassified under 2606.00, which is the code for aluminium ores and concentrates (bauxite). Once the bauxite has been chemically processed into aluminium oxide, it must move from Chapter 26 to Chapter 28.

FAQ

What is the HS code for Alumina?

The HS code for aluminium oxide (alumina), excluding artificial corundum, is 2818.20.

Is activated alumina classified differently?

No, activated alumina used for its adsorptive properties is generally classified under 2818.20, provided it remains chemically defined aluminium oxide.
