Stones, precious and semi-precious, dust and powder, of natural or synthetic precious or semi-precious stones, excluding diamonds.
Classification of precious stone dust under HS 7105.90
Precious stone dust and powder are classified under HS code 7105.90. This classification falls within Chapter 71, which covers natural or cultured pearls, precious or semi-precious stones, precious metals, and articles thereof. Heading 7105 is specifically for dust and powder of natural or synthetic precious or semi-precious stones. The heading is divided into two subheadings: 7105.10, which is reserved exclusively for diamond dust and powder, and 7105.90, which covers dust and powder from all other precious or semi-precious stones. This includes materials derived from rubies, sapphires, emeralds, garnets, amethysts, and other stones listed in the notes to Chapter 71. The dust or powder may be a byproduct of the cutting and polishing of stones (lapidary work) or may be produced by intentionally grinding stones of lower quality. These materials are widely used in industrial applications for grinding, polishing, and as abrasives on tools, as well as in certain high-end decorative finishes. The classification applies regardless of whether the source stone was natural or synthetic, provided it meets the definition of a precious or semi-precious stone and is in the form of dust or powder.

Codes often confused with 7105.90
Common mistake. The most frequent misclassification is using HS code 7105.10, which is strictly for diamond dust. Because diamonds are often processed alongside other precious stones, the dust is sometimes incorrectly grouped. Another common error is classifying the material under 2513.20 (emery or natural abrasives) or 2818.20 (aluminium oxide), especially if the dust is used for industrial grinding. However, if the dust originates from stones defined as precious or semi-precious in Chapter 71, heading 7105 takes precedence.

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).
