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.

Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If used solely as grinding wheels or abrasive segments
Millstones or grinding wheels of agglomerated synthetic diamonds classify under Chapter 68 as synthetic abrasives, not raw industrial diamonds.
If certified as synthetic diamonds rather than simulants
Synthetic or reconstructed diamonds, worked but not set, fall under heading 7104 specifically for synthetic precious stones.
If semi-worked into jewelry preforms
Semi-manufactured articles of precious stones for jewelers fall under 7116, differing from bulk industrial grade.

Import Tips & Compliance
• Verify synthetic origin with lab certificates to distinguish from natural diamonds and avoid gemstone headings
• Ensure documentation proves industrial end-use (e.g
• invoices specifying abrasive applications) to prevent reclassification as jewelry components
