HS code for Wire coiling machine: 8479.81
Machines and mechanical appliances, for treating metal, including electric wire coil-winders.
Classification of wire coiling machine under HS 8479.81
Wire coiling machines, particularly those used for winding electrical coils or treating metal wire in a coiling fashion, are classified under HS code 8479.81. Heading 8479 is a 'residual' heading that covers machines and mechanical appliances having individual functions, not specified or included elsewhere in Chapter 84. Subheading 8479.81 is specifically designated for machines used for treating metal, including electric wire coil-winders. This classification is appropriate because coiling for electrical purposes (like creating a solenoid or motor winding) is considered a specialized mechanical assembly function rather than a simple metal-shaping process. The machine's purpose is to precisely arrange wire into a coil, often around a core or bobbin, which is a distinct industrial process. This code is also used for machines that coil wire for non-electrical purposes if the machine's function is not better described as 'working wire' under 8463.30. The distinction often lies in whether the machine is shaping the wire into a structural form (8463) or winding it for functional/storage purposes (8479).

Codes often confused with 8479.81
Common mistake. The most frequent misclassification is HS code 8463.30. While 8463.30 covers machines for 'working wire,' 8479.81 is the more specific code for 'coil-winders' as per the Explanatory Notes to the Harmonized System. Another error is using 8537 for electrical control panels that might be attached to the machine, but the machine itself must be classified under 8479.81.
Top exporters and importers of HS 847981 (the code used for wire coiling machine), 2025
In 2025, the largest exporter of HS 847981 (the code used for wire coiling machine) in UN Comtrade data was China, with 38% of world exports; the largest importer in UN Comtrade data was Mexico, with 12% of world imports. Countries that did not report 2025 data are estimated from partner records, which can understate them.

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).
