Industrial Diamond Microns for Lapping
Industrial diamond microns for lapping, precisely graded diamond grit from 1 to 50 microns for polishing semiconductors, optics, and precision bearings. These are worked industrial diamonds in powder form, but per subheading note 1, powder requires 90% passing a 0.5mm sieve; these microns are finer and fall under tariff item 7102.29.00 as 'other'.
