Product classification
HS code for Threading tools: 8207.40
Tools, interchangeable, (for machine or hand tools, whether or not power-operated), tools for tapping or threading.
Classification of threading tools under HS 8207.40
Threading tools are classified under HS code 820740 because they represent interchangeable tools designed for tapping or threading operations, whether utilized in hand-operated tools or power-operated machine tools. This classification falls within Chapter 82, which covers tools, implements, and cutlery of base metal. The specific subheading 820740 is reserved for tools that create internal threads (tapping) or external threads (threading). These tools are characterized by their ability to be swapped in and out of a primary machine or tool holder, such as a lathe, drill press, or manual tap wrench. The classification logic depends on the tool's function as an interchangeable component that performs a specific cutting or forming action on a workpiece to produce screw threads. Because these tools are typically made of high-speed steel or carbide to withstand the friction of metalworking, they are distinct from the machines that drive them.

Codes often confused with 8207.40
Common mistake. Threading tools are frequently confused with HS code 8205, which covers general hand tools not elsewhere specified. However, if the tool is an interchangeable bit or die, 820740 is the correct designation. Another common error involves HS code 8466, which covers parts and accessories for machine tools. While threading tools are used with machines, they are classified as tools in Chapter 82 rather than machine parts in Chapter 84. Additionally, solid-state threading machines themselves are classified under 8459, not 8207.
Top exporters and importers of HS 820740 (the code used for threading tools), 2025
In 2025, the largest exporter of HS 820740 (the code used for threading tools) in UN Comtrade data was Germany, with 29% of world exports; the largest importer in UN Comtrade data was the United States, with 14% of world imports. Countries that did not report 2025 data are estimated from partner records, which can understate them.

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).
