HS Code for Aluminum hydroxide

HS code 281830 is specifically designated for "Aluminium hydroxide". This code falls under Chapter 28, which covers inorganic chemicals. Aluminum hydroxide (Al(OH)3) is a distinct chemical compound, and its classification here reflects its nature as a refined inorganic chemical substance, rather than a raw material ore or a fabricated aluminum product. This precise classification is essential for distinguishing it from other aluminum compounds or forms.

Products Included

• Aluminum trihydroxide
• Hydrated alumina
• Gibbsite
• Bayerite
• Boehmite (hydrated aluminum oxide, often grouped with hydroxide for classification purposes)

Common Misclassification

281820 (Aluminium oxide, other than artificial corundum): Aluminum oxide (alumina) is chemically distinct from aluminum hydroxide. While both are aluminum compounds, the presence of hydroxyl groups (-OH) in hydroxide differentiates it. Misclassification can occur if the precise chemical formula and composition are not accurately considered.
260600 (Aluminium ores and concentrates): Aluminum hydroxide is a refined chemical product, not a raw ore like bauxite. Bauxite is the primary source for aluminum hydroxide, but it is a mineral mixture, not the pure chemical compound itself.
281810 (Artificial corundum): Artificial corundum is a manufactured abrasive form of aluminum oxide, not aluminum hydroxide. Their applications and chemical structures are entirely different.

FAQ

What is the HS code for Aluminum hydroxide?

Aluminum hydroxide is classified under HS code 281830. This code is specifically allocated for the chemical compound "Aluminium hydroxide" within Chapter 28, which covers inorganic chemicals. This ensures its accurate identification as a distinct chemical substance for international trade.

What is the difference between aluminum hydroxide and aluminum oxide for HS classification?

For HS classification, aluminum hydroxide (HS 281830) is a distinct chemical compound containing hydroxyl groups (Al(OH)3). Aluminum oxide (HS 281820), or alumina, is a different chemical compound (Al2O3) without hydroxyl groups. The presence or absence of these chemical groups is the fundamental differentiator for their respective HS codes.
