HS-6 · Subheading
281820
Aluminium oxide; other than artificial corundum
Heading 2818 — Aluminium oxide (including artificial corundum); aluminium hydroxide
Chapter 28: Inorganic chemicals
Plain-language overview
Use HS-6 281820 when importing or exporting aluminum oxide, specifically forms that are not artificial corundum. For example, this code applies to shipments of calcined aluminum oxide used in abrasives or ceramics.
This code is distinct from HS-6 281810, which covers artificial corundum. If your product is synthetic corundum, you should classify it under that line instead.
Aluminum oxide under this code is typically used in various applications, including as a refractory material, in the production of aluminum metal, or as an abrasive in grinding wheels.
When considering this HS-6, note that aluminum hydroxide (classified under HS-6 281830) is a different compound and serves different industrial purposes, such as in water purification or as a flame retardant.
