Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If processed into calcined bauxite rather than fused corundum
Bauxite, even refined, remains under Chapter 25 as natural mineral products, not synthetic aluminum oxide.
If for refractory-grade grains shaped into bricks or blocks
Shaped refractory products of aluminum oxide classified in Chapter 69, not bulk grains.
If in the form of sintered carbides rather than pure oxide
Carbide forms like silicon carbide fall under 2849, distinct from pure aluminum oxide corundum.

Import Tips & Compliance
• Request ISO-certified lab reports confirming >98% Al2O3 content to avoid reclassification as lower-grade preparations
• Declare exact particle size distribution; finer powders may trigger additional dust handling requirements at customs
• Check for anti-dumping duties on Chinese-origin white fused alumina; use country-of-origin certificates
