About HS Code 281820
This HS code covers various forms of aluminum oxide (Al2O3) other than artificial corundum, encompassing a broad range of industrial applications. This includes activated alumina, used as a desiccant and catalyst support; tabular alumina, known for its high density and thermal shock resistance in refractories; and calcined alumina for non-abrasive uses such as ceramics, glazes, and as a raw material for aluminum metal production. Importers and exporters include chemical manufacturers, petrochemical companies, ceramics producers, and metallurgical industries. Key aspects for trade involve the specific crystalline phase (e.g., alpha, gamma), surface area, porosity, and purity, all of which are critical for its performance in catalytic, adsorbent, or refractory applications. Its versatility makes it a fundamental chemical commodity.
Products Under This Code
Activated alumina, Tabular alumina, Calcined alumina (non-abrasive), Gamma alumina, Alpha alumina
Real World Examples
BASF Activated Alumina, Almatis Tabular Alumina, Sasol Alumina
Common Misclassification
Often confused with artificial corundum (2818.10) due to shared chemical composition, but distinguished by manufacturing process and primary application; also, bauxite (2606.00) is the raw ore, not processed alumina.
Products Classified Under 2818.20
Industry
This code belongs to the Chemicals industry.
Trade Overview
Australia, China, and Brazil are major producers of raw alumina, with Germany and the USA also significant in specialized forms.
