HS Code 7102.21 – Diamonds; industrial, unworked or simply sawn, cleaved or bruted, but not mounted or set
HS code 7102.21 is the 6-digit subheading for diamonds, industrial, unworked or simply sawn, cleaved or bruted, but not mounted or set. It is used for rough industrial diamonds, diamond grit for abrasives, diamond powder (coarse), diamond saw blades (raw material) and diamond drill bits (raw material).
What HS 7102.21 covers
This HS code specifically covers industrial diamonds that are either unworked (raw) or have undergone only initial, basic processing such as sawing, cleaving, or bruting. These diamonds are not intended for jewelry but for various industrial applications due to their extreme hardness. Importers are typically manufacturers of cutting tools, abrasives, drilling equipment, and high-precision machinery. Exporters are often diamond mining companies or specialized industrial diamond suppliers. Key considerations in trade include the diamond's hardness, crystal structure, and purity, which determine its suitability for specific industrial uses like grinding, drilling, or polishing other hard materials. The market for industrial diamonds is driven by manufacturing, construction, and technological advancements requiring superhard materials. Unlike gem diamonds, their value is based on functional properties rather than aesthetic appeal.

Codes often confused with 7102.21
Common mistake. This code is differentiated from 710229 (other industrial diamonds) by the "unworked or simply processed" criterion, and from 710231 (non-industrial, unworked) by its designated industrial use.
Top exporters and importers of HS code 710221, 2025
In 2025, the largest exporter of HS code 710221 in UN Comtrade data was Angola, with 88% of world exports; the largest importer in UN Comtrade data was the United Arab Emirates, with about 86% of world imports. Zimbabwe 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 69% of its exports here ($161M, 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 marked * did not, so their figures add up what other countries recorded trading with them, and their exports are valued at buyers' CIF prices. 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).
