HS Code for Artificial corundum

HS code 281810 is specifically designated for aluminium oxide and artificial corundum. This classification covers synthetic forms of aluminium oxide (Al₂O₃) produced through various industrial processes, distinguishing them from naturally occurring corundum. Artificial corundum is highly valued for its hardness, chemical inertness, and high melting point, making it suitable for a wide range of industrial applications. The code encompasses the material in its primary forms, prior to significant processing into finished articles, focusing on the chemical compound itself and its synthetic variant.

Products Included

• Fused alumina (e.g., white fused alumina, brown fused alumina)
• Calcined alumina
• Tabular alumina
• Bubble alumina
• Sintered alumina
• High-purity synthetic aluminium oxide powders and grains

Common Misclassification

Misclassification can occur with related aluminium compounds or highly processed forms. HS code 281820 covers aluminium hydroxide, which is a distinct chemical compound (Al(OH)₃) and should not be confused with aluminium oxide. HS code 281830 covers other forms of aluminium oxide, which might include naturally occurring corundum or specific grades of aluminium oxide not considered "artificial corundum" in the context of 281810. Furthermore, if artificial corundum is processed into specific abrasive tools (e.g., grinding wheels), it would fall under Chapter 68. If it is used as a synthetic gemstone (e.g., synthetic ruby or sapphire), even though chemically identical, it might be classified under Chapter 71 (e.g., 710420 for unworked synthetic stones), depending on its form and intended use, as 281810 primarily covers the bulk industrial material.

FAQ

What is the HS code for Artificial corundum?

The HS code for artificial corundum, which is a synthetic form of aluminium oxide, is 281810.

What is the primary use of artificial corundum classified under HS 281810?

Artificial corundum classified under HS 281810 is primarily used in industrial applications requiring high hardness and wear resistance, such as in the manufacture of abrasives (e.g., sandpaper, grinding wheels), refractories (e.g., furnace linings), and advanced ceramics.
