Aluminium oxide; other than artificial corundum

HS v2017 Code: 281820

About aluminium oxide; other than artificial corundum

HS code 281820 covers the classification of aluminium oxide, a versatile and widely-used industrial mineral. Aluminium oxide, also known as alumina, is a key raw material in the production of aluminium metal, as well as a crucial component in various industrial applications. This industry plays a vital role in the global economy, supporting industries ranging from construction and transportation to electronics and ceramics.

Production process

Aluminium oxide is primarily produced through the Bayer process, a two-stage refining method. The first stage involves extracting alumina from bauxite ore through a series of chemical reactions. The second stage involves calcining the alumina to remove any remaining impurities, resulting in a high-purity aluminium oxide product.

Production inputs

The main inputs for the production of aluminium oxide under HS code 281820 include bauxite ore, which serves as the primary raw material, as well as various chemical reagents and energy sources required for the Bayer process. Additionally, specialized equipment and machinery, such as digesters, clarifiers, and calciners, are essential for the efficient and large-scale production of aluminium oxide.

Production outputs

The primary output of HS code 281820 is aluminium oxide, which is then used as a feedstock for the production of 760110 aluminium, a widely-used metal in numerous industries. Aluminium oxide also finds applications in the manufacturing of 690610 ceramic tiles, 840820 turbochargers, and 854430 electrical insulators, among other products.
