Tabular Alumina Granules 3-6mm from China
Tabular alumina granules sized 3-6mm, produced by sintering calcined alumina into dense, alpha-phase crystals, used in refractories. This artificial corundum in grain form, ground and refined, qualifies under HTS 2818.10.20 as chemically defined aluminum oxide. Offers superior thermal shock resistance.

Import Tips
• Submit X-ray diffraction analysis confirming alpha-alumina structure for proper chemically defined status
• Avoid common pitfall of declaring as 'calcined bauxite' which is 2606.00.0060
• For high-volume shipments, consider bonded warehouse storage to manage duties on inventory
