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.

Alternative Classifications

This product could be classified differently depending on its characteristics or intended use.

2818.20.00Lower: Free vs 7.5%

If processed into powder or granules

Refined or ground artificial corundum classifies under 2818.20, excluding crude blocks.

3824.99Higher: 15% vs 7.5%

If chemically modified with binders for specific industrial prep

Additives or preparations move it from pure chemically defined Chapter 28 compounds.

6902.20.10Higher: 35% vs 7.5%

If sintered into refractory bricks

Sintered alumina products become ceramic refractories in Chapter 69.

Import Tips & Compliance

Verify purity and chemical definition per Chapter 28 Note 1 to confirm artificial corundum status; provide lab analysis certificates

Ensure crude form (blocks/ingots) via photos/docs; processed grains shift to 2818.10.20

Declare exact fusion process and Al2O3 content to avoid misclassification as natural corundum (2513.10)
