Product classification
HS code for Diamond powder: 7105.10
Stones, precious and semi-precious, dust and powder, of diamonds.
Classification of diamond powder under HS 7105.10
Diamond powder and dust are classified under HS code 7105.10. This heading is situated within Chapter 71, which encompasses precious stones, semi-precious stones, and precious metals. The classification applies to both natural and synthetic diamond particles that have been reduced to a powder or dust form. Diamond powder is a critical industrial material used for its extreme hardness, serving as an abrasive in polishing pastes, grinding wheels, and cutting tools. The classification is based on the physical state of the diamond (powder or dust) rather than its chemical purity or the method of production (natural vs. synthetic). The size of the particles can range from sub-micron levels to larger grit sizes used in heavy industrial applications. Unlike larger diamonds used in jewelry or as industrial stones (which fall under 7102), 7105.10 is strictly reserved for the dust and powder form of the mineral.

Codes often confused with 7105.10
Common mistake. Diamond powder is often misclassified under 7102 (Diamonds, whether or not worked) or 7104 (Synthetic or reconstructed precious stones). 7102 is for whole stones, while 7105.10 is specifically for powder and dust. 7104 is for synthetic stones in forms other than powder. Additionally, diamond-impregnated tools are sometimes confused with the powder itself, but those belong in Chapter 68 or 82.

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).
