Overview
This HTS category, 2818.20.00.00, specifically covers aluminum oxide (alumina) that is not classified as artificial corundum. This designation typically includes various forms of refined aluminum oxide, such as calcined alumina, fused alumina, and activated alumina. These materials are distinguished by their chemical composition and physical form, and are produced through processes that yield a high purity aluminum oxide.
It is crucial to differentiate this category from its sibling, 2818.10, which is reserved for artificial corundum. Artificial corundum, whether chemically defined or not, is characterized by its crystalline structure, often produced through fusion processes in electric furnaces, and is primarily valued for its hardness and abrasive properties. Aluminum hydroxide, classified under 2818.30.00.00, represents a distinct chemical compound, a hydrated form of aluminum oxide, and is a precursor material for producing anhydrous alumina.
As this is a leaf node within the HTS classification, there are no further subcategories. Therefore, the focus for classification within 2818.20.00.00 lies on identifying aluminum oxide that does not meet the specific criteria for artificial corundum or aluminum hydroxide. Practical classification will depend on the manufacturing process, intended use (e.g., as a refractory material, filler, or catalyst support), and the physical characteristics of the aluminum oxide presented for import or export.
