Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If presented as sintered micro-powder
Sintered synthetic precious stone powders for industrial use may classify as inorganic bases in Chapter 28.
If incorporated into ceramic matrix composites
Articles of ceramic with diamond reinforcement classify in Chapter 69, not as loose precious stone powder.
If used in imitation jewelry production
Synthetic diamond powder incorporated into costume jewelry (no precious metal/stones) falls under imitation jewelry.

Import Tips & Compliance
• Provide SEM analysis confirming diamond structure and synthetic origin to distinguish from carbon nanomaterials
• Ship in inert atmosphere packaging to prevent oxidation; declare protective gas if applicable
• Document end-use as coating precursor to avoid 7113 classification as goldsmiths' wares
