HS Code for Aluminum oxide

Harmonized System (HS) code 281820 is designated for aluminum oxide, specifically excluding artificial corundum. This classification falls under Chapter 28, which covers inorganic chemicals. Aluminum oxide, also known as alumina, is a chemical compound of aluminum and oxygen. Its classification here emphasizes its identity as a distinct chemical substance rather than a manufactured article or a naturally occurring mineral in its raw state. The exclusion of artificial corundum is critical, as that specific form, often used as an abrasive or gemstone, has a separate classification within the same heading.

Products Included

• Non-corundum aluminum oxide
• Alumina (various forms, excluding abrasive grades or artificial gems)
• Calcined alumina
• Hydrated alumina (if not specifically classified elsewhere)
• Activated alumina (for desiccant or catalyst applications)

Common Misclassification

A common misclassification occurs with HS code 281810, which is specifically for artificial corundum. While both are forms of aluminum oxide, 281820 explicitly excludes the artificial corundum covered by 281810 due to its distinct properties and uses. Another potential confusion is with 281830 (Aluminum hydroxide), a related but chemically distinct compound. Furthermore, natural corundum, if unworked, would typically fall under Chapter 25 (e.g., 2513 for pumice stone, emery, natural corundum) or Chapter 71 for precious stones, not under 281820.

FAQ

What is the HS code for Aluminum oxide?

The HS code for aluminum oxide, excluding artificial corundum, is 281820.

What is the difference between natural and artificial corundum in HS classification?

Natural corundum, in its raw or unworked state, is generally classified under Chapter 25 or 71 depending on its form and quality. Artificial corundum, a manufactured product, is classified under HS code 281810. HS code 281820 specifically covers other forms of aluminum oxide, distinct from both natural and artificial corundum.
