Diamonds, industrial, (other than unworked or simply sawn, cleaved or bruted), but not mounted or set.
Classification of polished industrial diamonds under HS 7102.29
Polished industrial diamonds are classified under HS code 7102.29. Heading 7102 covers diamonds, whether or not worked, but not mounted or set. The "industrial" designation (7102.2) is applied to diamonds intended for technical or industrial use, such as cutting, grinding, or drilling, rather than for jewelry. Subheading 7102.29 specifically covers those that have been worked beyond being simply sawn, cleaved, or bruted—meaning they have been polished or faceted—but are still intended for industrial applications. This classification is critical because it separates industrial-grade stones from "non-industrial" or gemstone-quality diamonds found under 7102.39. The distinction is based on the physical characteristics of the stone (color, clarity, inclusions) and its intended end-use in industrial machinery or precision tools. Even if a diamond is polished to a high degree, if its primary application is for a high-pressure anvil or a precision cutting tool, it remains under the industrial classification. Customs may require proof of industrial grade, such as technical specifications or evidence of the stone's unsuitability for use in the jewelry trade.

Codes often confused with 7102.29
Common mistake. Common misclassifications include 7102.21, which is for unworked or simply sawn industrial diamonds. Another frequent error is 7102.39, which is for worked non-industrial (gemstone) diamonds. Additionally, if the diamond is already mounted in a tool, it should be classified under 8207.19 or 8209.00 rather than 7102.

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).
