Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If coarser than 80 mesh
Diamonds 20 mesh up to but not including 80 mesh fall under .10; powder definition still applies if 90% through 0.5mm.
If processed into millstones or grinding wheels
When bound into abrasive tools rather than sold as loose powder, classification shifts to Chapter 68 for worked grinding materials.
If used in jewelry polishing compounds
Mixtures containing this powder with binders for final jewelry use may classify as 'other' precious metal/jewelry articles.

Import Tips & Compliance
• Verify sieve test certification showing 90%+ passes 0.5mm mesh to confirm 'powder form' per subheading note
• Provide diamond origin documentation (e.g
• Kimberley Process for natural stones) to avoid reclassification
• Avoid common pitfall of mislabeling coarser grits; exact mesh size must match statistical suffix .11
