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.

Alternative Classifications

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

2818.10.20Higher: 8.8% vs 7.5%

If crushed into abrasive grains

Graded or sized particles are not crude, shifting to the processed subheading.

2524.90.00Higher: 25% vs 7.5%

If natural crocidolite origin mistaken

Natural asbestos minerals are in Chapter 25; artificial requires chemical synthesis proof.

2849.20Higher: 10.5% vs 7.5%

If containing >15% boron or carbides

Carbide inclusions per Chapter note classify under 2849 carbides.

Import Tips & Compliance

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
