Synthetic Diamond Micron Powder for Wire Sawing
Ultra-fine synthetic diamond powder (90%+ passing 0.5mm sieve) used in wire sawing for semiconductor wafers and optical glass. HTS 7102.29.0050 covers industrial 'other' worked diamonds, excluding powder forms only if not meeting sieve criteria, but this qualifies as worked industrial material.

Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If chemically classified as synthetic industrial abrasive
Synthetic industrial diamonds in powder form may shift to Chapter 28 if emphasized as chemical compounds rather than worked stones.
If when bound into natural abrasive wheels
Articles of agglomerated synthetic diamonds for grinding classify under 6805 as finished abrasive tools.
If for higher purity gem-quality synthetic powder
Powdered synthetic diamonds for jewelry or optics fall under 7104 as reconstructed precious stones.

Import Tips & Compliance
• Provide sieve analysis certificates confirming 90%+ passes 0.5mm mesh per subheading notes for powder classification
• Label clearly as 'industrial abrasive powder' to avoid confusion with synthetic gem powders under 7104
