Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If natural rather than artificial/synthetic corundum
Natural corundum (emery) from mineral sources classified in Chapter 25, lacking artificial fusing process.
If doped with elements for electronic applications and cut into wafers
Doped chemical elements in worked forms (discs/wafers) move to 3818 per Chapter note.
If for rare earth-modified aluminum oxide salts
Complex salts or peroxysalts of aluminum fall under specific 2826-2842 headings.

Import Tips & Compliance
• Provide furnace fusion process documentation to distinguish from natural abrasives; prevents Chapter 25 misclassification
• Comply with REACH-like regulations for import; label for respiratory hazards from respirable crystalline silica traces
• Bulk shipments require proper ventilation declarations; smaller retail packs may shift to 6805.10
