Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If bound into grinding wheels or mounted on tools
Millstones, grindstones, and similar articles of agglomerated synthetic diamonds classify in Chapter 68, not as loose powder.
If natural diamond powder
Natural diamond dust/powder falls under separate subheading 7105.21, differentiated by origin despite identical powder form.
If chemically treated for semiconductor polishing
Precipitated or sintered synthetic diamonds prepared for specific industrial polishing may classify as inorganic compounds in Chapter 28.

Import Tips & Compliance
• Verify powder fineness via sieve test (90%+ through 0.5mm mesh) to confirm HTS 7105.10.0050 classification; coarser grit may shift to 6804.21
• Provide lab certification proving synthetic origin and diamond composition to avoid misclassification as natural under 7105.21
• Declare exact particle size distribution and end-use to prevent customs reclassification as finished abrasives
