Aluminium oxide; other than artificial corundum

HS code 281820 covers the classification of aluminium oxide, a versatile and widely-used industrial chemical. Aluminium oxide, also known as alumina, is a key material in the production of aluminium metal, as well as a range of other applications across various industries. Its importance in the global economy stems from its unique physical and chemical properties, making it an essential component in the manufacturing of a diverse array of products.

The primary production technique for aluminium oxide is the Bayer process, which involves the extraction of alumina from bauxite ore. This multi-step process includes crushing, grinding, and chemical treatment to separate the alumina from the other components of bauxite. The resulting alumina is then calcined at high temperatures to produce the final aluminium oxide product.

The main inputs required for the production of aluminium oxide under HS code 281820 include bauxite ore, which serves as the primary raw material, as well as energy sources, such as electricity and fuel, to power the various stages of the Bayer process. Additionally, the production may require specialized equipment, such as crushers, grinders, and calcination furnaces, to facilitate the extraction and refinement of the alumina.

The primary output of HS code 281820 is aluminium oxide, which is then used as a feedstock for the production of 760110 Aluminium, not alloyed under HS code 760110. Aluminium oxide is also widely used in the manufacture of 381700 Chemical preparations for ceramic, enamelling or glassmaking under HS code 381700, as well as in the production of abrasives, catalysts, and various other industrial applications.
