HS Code 8479.81 – Machines and mechanical appliances; for treating metal, including electric wire coil-winders
HS code 8479.81 is the 6-digit subheading for machines and mechanical appliances, for treating metal, including electric wire coil-winders. It is used for electric wire coil-winding machines, deburring machines for metal, shot blasting machines, metal polishing machines and ultrasonic metal cleaning systems.
What HS 8479.81 covers
This HS code encompasses a diverse range of specialized machines and mechanical appliances primarily used for treating metal, excluding those covered by more specific categories like machine tools (Chapter 84, headings 8456-8466). A notable inclusion is electric wire coil-winders, which are crucial for manufacturing electric motors, transformers, and inductors. Beyond coil-winders, this category includes various other machines for metal treatment such as deburring machines, polishing machines, shot blasting machines, and specialized cleaning or surface preparation equipment. These machines are vital across numerous manufacturing sectors, including automotive, electronics, aerospace, and general engineering, where precise metal finishing and component preparation are essential. Major importers are industrialized nations with strong manufacturing bases, like China, USA, Germany, and Japan. Exporters are typically specialized engineering firms from Germany, Italy, Japan, and the USA, known for their precision and robust industrial equipment.

Codes often confused with 8479.81
Common mistake. This code can be confused with metalworking machine tools (8456-8466) which perform shaping or cutting operations. 847981 is for *treating* metal (e.g., surface finishing, winding), not for machining it. It's also distinct from 8463 (other machine tools for working metal without removing material) by its broader scope of "treating" and specific inclusion of coil-winders.
Top exporters and importers of HS code 847981, 2025
In 2025, the largest exporter of HS code 847981 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).
