HS code for Chuck: 8466.20
Parts & accessories suited for use solely/principally with machines of headings 8456-8465, work holders.
Classification of chuck under HS 8466.20
A chuck is classified under HS code 8466.20. This classification is found within Chapter 84, which covers nuclear reactors, boilers, machinery, and mechanical appliances. Heading 8466 is specifically designed for parts and accessories suited for use solely or principally with the machine tools of headings 8456 to 8465 (which include lathes, milling machines, and drills). Subheading 8466.20 is dedicated to "work holders." A chuck is a specialized type of work holder used to grip a workpiece (or sometimes a tool) and hold it securely while it is rotated or operated upon. Because the chuck is an accessory that enhances the functionality of a machine tool rather than being a machine itself or a simple interchangeable tool, it is correctly placed in this parts and accessories category. This applies to various mechanical, pneumatic, or hydraulic gripping systems used in industrial machining.

Codes often confused with 8466.20
Common mistake. Chucks are frequently misclassified under HS code 8466.10, which is for "tool holders." While some chucks (like drill chucks) hold tools, the General Interpretative Rules and the specific structure of 8466 usually prioritize the work-holding function or group them under 8466.20. Another common error is 8207, which covers interchangeable tools for hand tools or machine tools. However, 8207 is for the cutting bit or the drill itself, not the mechanism that holds it. Finally, parts of chucks should also be classified under 8466.20 as parts of work holders.

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).
