Pink Aluminum Oxide Abrasive Grit 98% Al2O3
Pink fused aluminum oxide grit containing 98% Al2O3, doped with chromium oxide for enhanced toughness and heat resistance. Falls under HTS 2818.10.20.10 due to its ruby/pink coloration and high purity as artificial corundum in pulverized form. Ideal for resin-bonded abrasives and high-speed grinding.

Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If containing 97.5% or less Al2O3
Purity threshold determines subheading; lower purity shifts to general artificial corundum.
If sintered into refractory bricks
High-Al2O3 corundum formed into refractory shapes classifies as ceramic goods, not raw material.
If doped for semiconductor polishing slurries
Electronic-grade modifications create prepared compounds outside pure Chapter 28 scope.

Import Tips & Compliance
• Submit lab test reports confirming Al2O3 purity and pink/ruby hue from chromic oxide doping
• Declare exact particle size range (e.g
• 16-220 mesh) to confirm 'ground/pulverized' status
• Avoid classifying as lower-purity if trace elements exceed specs; frequent audit trigger
