More Specific Codes
This product may fall under a more specific subheading:
Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If pre-mounted on tool holders as cutting inserts
Mounted diamond inserts for tools classify under interchangeable tools heading 8207
If synthetic but shaped for specific industrial tools
Worked synthetic diamonds as tool components go to 7104.90 rather than raw material
If in chemical suspension for slurry applications
Diamond suspensions for lapping/polishing classify as prepared chemical products

Import Tips & Compliance
• Provide CVD process certification distinguishing from HPHT diamonds; declare thickness/specifications accurately
• Ensure no gem-quality clarity to prevent 7102.31 reclassification
• Industrial end-use statement prevents jewelry scrutiny
