Parts & accessories suited for use solely/principally with machines of headings 8456-8465, dividing heads and other special attachments for machines.

Classification of machine attachment under HS 8466.30

Machine attachments, specifically dividing heads and other specialized attachments for machine tools, are classified under HS code 8466.30. This code is situated within the category for parts and accessories suitable for use solely or principally with the machines of headings 8456 to 8465 (which include metal-working, wood-working, and stone-working machinery). The classification 8466.30 is designated for "dividing heads and other special attachments for machines." These are components that enhance or modify the machine's capability but are not the primary cutting tools themselves. This classification is determined by Note 2 to Section XVI, which governs the classification of parts of machinery, ensuring that specialized accessories are grouped with the machines they serve.

Codes often confused with 8466.30

Common mistake. Machine attachments are often misclassified under HS code 8466.93, which is a residual category for "other" parts for machines of headings 8456 to 8461. However, if the item is a dividing head or a special attachment, 8466.30 takes precedence as it is more specific. Another common error is using HS code 8207, which covers interchangeable tools (like drill bits or milling cutters). The distinction is that 8207 is for the consumable tool that performs the work, while 8466.30 is for the attachment that holds or moves the workpiece or the tool. General-purpose work holders may also be confused with 8466.20.

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).
