Classification of glazier's diamonds under HS 8205.59

Glazier's diamonds are classified under HS code 8205.59. This classification is found within Chapter 82, which covers tools, implements, cutlery, and base metal parts. Heading 8205 is a broad category for hand tools that are not specified in other headings of the chapter. Subheading 8205.59 is the residual category for "other" hand tools. A glazier's diamond is a specialized manual tool used for cutting or scoring glass. It typically consists of a small, industrial-grade diamond (natural or synthetic) mounted at the tip of a handle made of wood, plastic, or metal. The classification is determined by the tool's primary function as a hand-operated implement. Even though the tool incorporates a diamond, which is a precious or semi-precious stone, Note 1 to Chapter 82 allows for the inclusion of tools that use such stones as working parts, provided the tool remains a hand tool of a type used in the hand. The diamond serves as the cutting edge, allowing the glazier to score a precise line on the glass surface before snapping it.

Codes often confused with 8205.59

Common mistake. Glazier's diamonds are often misclassified under 7102.21 or 7102.29, which cover industrial diamonds as raw materials. However, once the diamond is mounted into a tool, it must be classified in Chapter 82. They may also be confused with 8207.90 (interchangeable tools), but because glazier's diamonds are complete hand tools in themselves rather than bits for a machine, 8205.59 is correct. Wheel-type glass cutters (using a metal wheel instead of a diamond) are also in 8205.59.

Top exporters and importers of HS 820559 (the code used for glazier's diamonds), 2025

In 2025, the largest exporter of HS 820559 (the code used for glazier's diamonds) in UN Comtrade data was China, with 39% of world exports; the largest importer in UN Comtrade data was the United States, with 16% of world imports. Taiwan 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 6.7% of its exports here ($36M, CEPII BACI), so it may rank higher.

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. UN Comtrade records Taiwan as "Other Asia, not elsewhere specified". Saudi Arabia's exports under that code are left out: they are far too large to be trade with Taiwan, so mostly undisclosed partners. 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).
