HS-4 · Heading
2818 — Aluminium oxide (including artificial corundum); aluminium hydroxide
Chapter 28: Inorganic chemicals
Plain-language overview
Use HS-4 2818 when importing aluminum oxide, including artificial corundum, or aluminum hydroxide. For example, if you're shipping a bulk container of artificial corundum for use in abrasives, this heading applies.
To distinguish between the subheadings, note that HS-6 281810 specifically covers artificial corundum, which is manufactured for abrasive and refractory purposes. If your product is aluminum oxide but not classified as artificial corundum, you would use HS-6 281820.
If you're importing aluminum hydroxide, which is often used in water purification or as a flame retardant, you should refer to HS-6 281830. This subheading is distinct from the aluminum oxides and is important for accurate classification.
