Crude Brown Fused Alumina from China
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.

Import Tips
• 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)
