Product classification
HS code for Coil winding machine: 8479.81
Machines and mechanical appliances, for treating metal, including electric wire coil-winders.
Classification of coil winding machine under HS 8479.81
The classification for a coil winding machine is HS code 8479.81. This code is situated within heading 8479, which acts as a "basket" category for machines and mechanical appliances that have individual functions but are not specified or included elsewhere in Chapter 84. The specific subheading 8479.81 is designated for machines used for treating metal, including electric wire coil-winders. These machines are essential for manufacturing electrical components such as transformers, inductors, motors, and solenoids. The classification is determined by the machine's specialized function of winding conductive wire into precise coils. According to the Explanatory Notes to the Harmonized System, this heading includes machines for winding electric wire onto bobbins or directly into motor armatures. It is important to distinguish these from textile winding machines, as the 8479.81 code specifically mentions the treatment of metal (wire). The mechanical complexity of these machines, which often includes tension control, layering mechanisms, and programmable logic controllers, does not change their classification as long as the primary function remains the winding of wire coils.

Codes often confused with 8479.81
Common mistake. Coil winding machines are often misclassified under 8445.40, which is the code for textile winding or reeling machines. While the mechanical action is similar, 8445 is strictly for textile yarns. Another common error is using 8479.89 (other mechanical appliances), but 8479.81 is more specific because it explicitly mentions electric wire coil-winders in the legal text of the subheading.
Top exporters and importers of HS 847981 (the code used for coil winding machine), 2025
In 2025, the largest exporter of HS 847981 (the code used for coil winding 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).
