Crude White Fused Alumina Blocks from China
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.

Import Tips
• Submit furnace fusion process documentation and Al2O3 purity (>99%) to distinguish from brown variants
• Avoid common pitfall of declaring as 'fused alumina grain' which falls under 2818.10.20.00
• Include MSDS for handling hazardous dust during crude block imports
