HS code for Taps and dies: 8207.40
Tools, interchangeable, (for machine or hand tools, whether or not power-operated), tools for tapping or threading.
Classification of taps and dies under HS 8207.40
Taps and dies are classified under HS code 820740 when they are designed as interchangeable tools for use in machine tools or power-operated hand tools. Heading 8207 is dedicated to tools that are not used independently but are fitted into machines (such as milling machines, lathes, or presses) or power tools (such as electric drills). Subheading 820740 specifically identifies tools for tapping or threading. These products are typically made from High-Speed Steel (HSS) or cobalt and are engineered to withstand high rotational speeds and significant thermal stress. The classification is based on the tool's "interchangeable" nature, meaning it is a consumable component of a larger mechanical system. This distinguishes them from the hand-operated versions found in heading 8205. The technical specifications, such as the shank type (e.g., Morse taper or specialized hex shanks for impact drivers), are the primary indicators for this classification.

Codes often confused with 8207.40
Common mistake. These are often confused with HS code 820510, which is reserved for tools that are exclusively hand-operated. Another common error is attempting to classify these under 8466 as "parts of machine tools." According to the Chapter 82 notes, tools of this heading (8207) are excluded from Chapter 84 even if they are used on machines. Furthermore, if the dies are used for drawing metal (rather than cutting threads), they might be incorrectly placed in 820720.
Top exporters and importers of HS 820740 (the code used for taps and dies), 2025

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).
