HS code for Diamond dust: 7105.10
Stones, precious and semi-precious, dust and powder, of diamonds.
Classification of diamond dust under HS 7105.10
Diamond dust is classified under HS code 7105.10 because it consists of fine particles or powder derived from natural or synthetic diamonds. According to the Harmonized System, Chapter 71 encompasses precious and semi-precious stones, precious metals, and articles thereof. Specifically, heading 7105 is reserved for dust and powder of natural or synthetic precious or semi-precious stones. The classification is determined by the physical state of the diamond material; while whole diamonds fall under 7102 or 7104, the pulverized form is strictly categorized here. This classification applies regardless of whether the dust is used for industrial abrasive purposes or in the manufacture of jewelry polishing compounds. The material must generally pass through a sieve with a mesh aperture of 0.5 mm to be considered dust or powder in this context. The distinction between natural and synthetic diamond dust is maintained at the subheading level, with 7105.10 specifically covering diamond-based powders, whereas 7105.90 covers powders of other precious stones like rubies or sapphires.

Codes often confused with 7105.10
Common mistake. Diamond dust is frequently misclassified under HS code 7102, which is reserved for whole or worked diamonds that are not yet in powder form. Another common error is using HS code 7104, which covers synthetic or reconstructed precious stones in larger forms. Additionally, some importers mistakenly use HS code 2513, which covers pumice stone and other natural abrasives, but diamond-based materials must remain in Chapter 71 due to their status as precious stones.

How these figures are built
109 countries reported 2025 trade to UN Comtrade in HS 2022, and their own totals are used. Countries that did not report are estimated from what other countries recorded trading with them. Those estimates miss trade with other non-reporting countries, so they can be low, and a non-reporting country can rank higher than shown or be missing from the list. World totals add both and leave out trade between two non-reporting countries. Figures are in current US dollars; reported imports are mostly valued CIF and exports FOB, and exports include re-exports. The UN Comtrade links show the underlying records; they can also list a few reporters left out here (regional groups and older HS editions).
