Products classified under HTS 2818.10.10.00
Crude Brown Fused Alumina
Crude brown fused alumina is produced by fusing bauxite in electric arc furnaces, resulting in a blocky, unprocessed form of artificial corundum with high aluminum oxide content. It falls under HTS 2818.10.10.00 as crude artificial corundum, not further processed into grains or powder. Primarily used as a raw material for abrasives after crushing and sizing.
Crude White Fused Alumina Blocks
Crude white fused alumina blocks are manufactured by fusing calcined alumina in high-temperature furnaces, yielding large, unrefined chunks of high-purity artificial corundum. Classified under HTS 2818.10.10.00 due to its crude state and chemical definition as aluminum oxide. Used in precision abrasives and refractories after processing.
Industrial Crude Bauxite-Derived Corundum
This crude artificial corundum is derived from high-grade bauxite fusion, supplied in large irregular lumps for further industrial breakdown. HTS 2818.10.10.00 applies as unprocessed artificial corundum, chemically defined per Chapter 28. Ideal for manufacturing grinding wheels and sandblasting media.
High-Density Crude Fused Alumina Ingots
High-density crude fused alumina ingots are large cast blocks from controlled fusion of alumina, offering superior hardness for abrasive applications. Falls under HTS 2818.10.10.00 as crude artificial corundum, meeting chemical purity standards. Processed into media for shot peening and polishing.
Tabular Crude Alumina Corundum Lumps
Tabular crude alumina corundum lumps are produced via sintering and fusion, resulting in dense, plate-like crude structures of artificial corundum. Classified in HTS 2818.10.10.00 for its unprocessed crude form and aluminum oxide composition. Used in advanced ceramics and refractories.
