Parts & accessories suited for use solely/principally with machines of headings 8456-8465, tool holders and self-opening dieheads.
Classification of tool holder under HS 8466.10
Tool holders are classified under HS code 8466.10. This code is situated within Chapter 84, which deals with mechanical machinery. Heading 8466 is a "parts and accessories" heading, specifically for those suited for use solely or principally with the machine tools of headings 8456 to 8465. Tool holders are critical interface components that secure a cutting tool (such as a drill bit, end mill, or lathe insert) to the spindle or turret of a machine tool. Because they are considered accessories that enhance or enable the function of the primary machine, they are classified here rather than as tools themselves. The distinction is important: the tool holder is the device that stays with the machine, while the "interchangeable tool" (the part that actually cuts the material) is classified in Chapter 82. Subheading 8466.10 specifically identifies tool holders and self-opening dieheads, separating them from work holders or other specialized parts. This classification applies regardless of whether the holder is for a manual lathe or a sophisticated CNC machining center, provided it is a device for holding the tool.

Codes often confused with 8466.10
Common mistake. Tool holders are often misclassified under heading 8207, which covers interchangeable tools for hand tools or machine tools. However, 8207 is for the cutting bits themselves (drills, dies, etc.), not the devices that hold them. They are also sometimes confused with 8466.20, which is for work holders (like vises or chucks that hold the workpiece rather than the tool).

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).
