Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If coarser synthetic diamonds not in powder form
Synthetic diamonds not meeting powder sieve test classify as industrial synthetic diamonds in heading 7104.
If assembled into polishing compounds or slurries
When mixed with binders into finished polishing pastes, it becomes 'other' articles of precious stones.
If sold as prepared chemical slurry for lapping
Powder incorporated into chemical preparations for specific lab use shifts to Chapter 38 chemical products.

Import Tips & Compliance
• Include technical data sheets specifying metal coating thickness and diamond particle size distribution to substantiate classification
• Avoid common error of classifying as synthetic industrial diamonds under 7104 if powder fineness qualifies it for Chapter 71
• Ensure invoice details synthetic nature and coating to prevent scrutiny under natural diamond provisions
