Product classification
HS code for Industrial heat treatment equipment: 8514.40
Heating equipment, for the heat treatment of materials by induction or dielectric loss, industrial or laboratory, other than furnaces and ovens.
Classification of industrial heat treatment equipment under HS 8514.40
Industrial heat treatment equipment utilizing induction or dielectric loss is classified under HS code 8514.40. This classification is part of Chapter 85, which covers electrical machinery and equipment. Heading 8514 specifically addresses industrial or laboratory electric furnaces and ovens, including those functioning by induction or dielectric loss. Subheading 8514.40 is the specific category for other equipment for the heat treatment of materials by induction or dielectric loss. This includes specialized machinery used for hardening, annealing, or tempering metals and other materials where the heat is generated within the material itself through electromagnetic fields. The classification is based on the electrical method of heat generation and the industrial application of the equipment for material processing.

Codes often confused with 8514.40
Common mistake. This equipment is often confused with resistance-heated furnaces classified under HS code 8514.10. The distinction is technical: 8514.10 relies on heating elements that transfer heat via radiation or convection, whereas 8514.40 uses electromagnetic fields to induce heat directly within the workpiece. Another common error is using HS code 8419, which covers non-electric industrial heating equipment. Because the equipment in question uses induction or dielectric loss—both electrical phenomena—it must remain within Chapter 85. Furthermore, if the equipment is a complete furnace or oven rather than a specialized heat treatment machine, it might be better suited for 8514.20. Precise technical specifications regarding the heating method are required.
Top exporters and importers of HS 851440 (the code used for industrial heat treatment equipment), 2025
In 2025, the largest exporter of HS 851440 (the code used for industrial heat treatment equipment) in UN Comtrade data was the United States, with 27% of world exports; the largest importer in UN Comtrade data was China, with 12% of world imports. Countries that did not report 2025 data are estimated from partner records, which can understate them.
Figures cover everything classified under HS 851440, not only industrial heat treatment equipment.

How these figures are built
109 countries reported 2025 trade to UN Comtrade in HS 2022, and their own totals are used. Countries marked * did not, so their figures add up what other countries recorded trading with them, and their exports are valued at buyers' CIF prices. 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. UN Comtrade records Taiwan as "Other Asia, not elsewhere specified". Saudi Arabia's exports under that code are left out: they are far too large to be trade with Taiwan, so mostly undisclosed partners. 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).
