Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If electroplated onto tool shanks
Synthetic diamonds individually mounted by electroplating classify as coated abrasives.
If containing silver matrix
Powders with silver ≥2% treated as silver alloys per note 5(c).
If saw-tooth set with diamonds
Diamond powders fixed in saw blades classify as metal saws/tools.
