Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If carbides rather than pure diamond phase
Nano-carbide materials classify under inorganic chemicals if not predominantly diamond.
If dispersed in liquid carrier
Nano-diamond suspensions are chemical preparations, not dry powders.

Import Tips & Compliance
• TEM/SEM reports essential for nano claims; CBP may require aggregation state clarification
• Declare biomedical vs industrial end-use; medical device powders face FDA overlay
• Hazard comms for nano-materials; SDS must note respirable fines risk
