HS code for Industrial diamond tools (unmounted): 7102.29
Diamonds, industrial, (other than unworked or simply sawn, cleaved or bruted), but not mounted or set.
Classification of industrial diamond tools (unmounted) under HS 7102.29
Industrial diamonds that are unmounted and have undergone some level of processing beyond being simply sawn or cleaved are classified under HS code 7102.29. This code is part of Chapter 71, which covers natural or cultured pearls and precious stones. The "industrial" designation is critical; these diamonds are intended for technical or industrial applications rather than jewelry. Because they are "unmounted," they have not yet been integrated into a tool or setting. The classification 7102.29 specifically excludes diamonds that are "unworked" (7102.21) and those that are already part of a finished tool (Chapter 82). The classification is based on the physical state of the stone and its intended use. Industrial diamonds are often used for their hardness and thermal conductivity in cutting, grinding, or drilling applications. Even if they are polished or faceted, if they are designated for industrial use and not yet mounted, they remain in this category.

Codes often confused with 7102.29
Common mistake. The most common misclassification is 7102.21, which is reserved for unworked or simply sawn industrial diamonds. Another frequent error is 8207.19, which covers rock drilling or earth boring tools with diamond working parts. If the diamond is already set into a metal shank or tool, it must be classified in Chapter 82. Additionally, synthetic diamonds are classified under 7104.21 or 7104.91, depending on their state, and should not be confused with the natural industrial diamonds of 7102.29.
Top exporters and importers of HS 710229 (the code used for industrial diamond tools (unmounted)), 2025
In 2025, the largest exporter of HS 710229 (the code used for industrial diamond tools (unmounted)) in UN Comtrade data was the United States, with 27% of world exports; the largest importer in UN Comtrade data was Indonesia, with 40% of world imports. Botswana did not report 2025 data, and its estimate from partner records misses its trade with other countries that did not report: in 2024 that was 99% of its exports here ($9.1M, CEPII BACI), so it may also belong among the top exporters.

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).
