HS Code 8466.20 – Parts & accessories suited for use solely/principally with machines of headings 8456-8465; work holders

HS code 8466.20 is the 6-digit subheading for parts & accessories suited for use solely/principally with machines of headings 8456-8465, work holders. It is used for machine vises, lathe chucks, magnetic chucks, vacuum chucks and clamping fixtures.

What HS 8466.20 covers

This HS code covers work holders, which are indispensable parts and accessories for machine tools classified under headings 8456-8465. Work holders are crucial for securely clamping workpieces during various machining operations like milling, turning, drilling, and grinding. Their primary function is to ensure stability, accuracy, and repeatability, which are vital for achieving high-quality finished products. This category includes a wide range of devices, from manual vises and hydraulic chucks to magnetic and vacuum clamping systems. Industries such as automotive, aerospace, general engineering, and mold making heavily rely on these components. Countries with robust manufacturing bases, particularly those involved in precision engineering, are the main importers and exporters. Trade focuses on factors like clamping force, precision, versatility, and the ability to integrate with automated production lines to enhance operational efficiency and safety.

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).
