Synthetic Diamond Powder Coated with Silver
Fine synthetic diamond powder where 90% or more passes through a 0.5 mm sieve, coated with a thin layer of silver metal for enhanced thermal conductivity. Classified under HTS 7105.10.0020 due to being synthetic diamond dust/powder explicitly coated with metal. Used primarily in electronics for heat sinks and thermal pastes.

Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If no metal coating applied
Uncoated synthetic diamond powders fall under the base subheading without metal coating specification.
If for industrial grinding or polishing use, regardless of coating
If marketed primarily as synthetic diamond for abrasive wheels or tools, it shifts to Chapter 68 millstones/abrasives.
If chemically treated as synthetic precious stone precursor
Certain synthetic gemstone powders used in chemical manufacturing may classify under inorganic chemicals if not meeting jewelry Chapter 71 notes.

Import Tips & Compliance
• Verify coating composition via spectrometry to confirm 'coated with metal' status and avoid reclassification as uncoated powder under 7105.10.0010
• Provide lab certification proving 90%+ passes 0.5mm sieve and synthetic origin to meet subheading powder definition
• Declare exact metal coating (e.g
• silver) and weight percentage; common pitfall is undervaluing high-conductivity coatings
