Products classified under HTS 7102.29.00.50
Monocrystalline Synthetic Diamond for Laser Drilling
Worked monocrystalline synthetic diamonds, not set, for nozzles in laser drilling of oil/gas wells. Under HTS 7102.29.0050 as industrial 'other' diamonds per Chapter 71, excluding jewelry or mounted forms.
Industrial Synthetic Rutile-Coated Diamond Particles
Synthetic diamond particles coated with rutile for enhanced dispersion in resin-bonded tools. HTS 7102.29.0050 as 'other' industrial worked diamonds, not powder if >0.5mm sieve.
PCD Polycrystalline Diamond Compact Blanks
Polycrystalline diamond compact (PCD) blanks sintered for cutting tool inserts in machining. Unmounted, under HTS 7102.29.0050 as industrial 'other' diamonds.
Synthetic Diamond Extrusion Dies
Worked synthetic diamond dies for wire extrusion in electronics. HTS 7102.29.0050 industrial.
CVD Diamond Windows for Sensors
CVD diamond windows, worked for IR sensors in harsh environments. Industrial HTS 7102.29.0050.
Synthetic Cubic Zirconia Industrial Cutting Stones
Synthetic cubic zirconia stones, precisely cut but not mounted or set, used in industrial grinding and cutting applications for materials like glass and ceramics. Classified under HTS 7102.29.0050 as industrial diamonds (broadly including synthetic diamond simulants for industrial use), meeting the 'other worked' category for non-gem purposes. Exceeds 90% purity standards for industrial abrasive use.
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.
Industrial CVD Diamond Films for Heat Sinks
Chemically vapor-deposited (CVD) polycrystalline diamond films, worked but unmounted, for thermal management in electronics heat sinks. Falls under HTS 7102.29.0050 as 'other' industrial diamonds, worked for non-jewelry applications per Chapter 71 notes.
HPHT Synthetic Diamond Dresser Blanks
High-pressure high-temperature (HPHT) synthetic diamond blanks shaped for single-point dressers in grinding wheel truing. HTS 7102.29.0050 applies to these 'other' worked industrial diamonds, not mounted, used in metalworking.
Synthetic Diamond Lapping Plates
Flat synthetic diamond lapping plates, worked surfaces for precision polishing of mechanical seals and bearings. Classifies in HTS 7102.29.0050 for unmounted industrial diamonds, 'other' category.
