Product classification

HS code for Induction furnace: 8514.20

Furnaces and ovens, electric, for industrial or laboratory use, functioning by induction or dielectric loss.

Classification of induction furnace under HS 8514.20

Induction furnaces are classified under HS code 8514.20. This code is situated in Chapter 85, which covers electrical machinery and equipment. Heading 8514 is dedicated to industrial or laboratory electric furnaces and ovens. The subheading 8514.20 specifically identifies equipment that functions by induction or dielectric loss. Classification is driven by the primary heating technology—electromagnetic induction—and the intended environment, which must be industrial or laboratory-based. These machines utilize high-frequency alternating current passed through a coil to create a magnetic field, inducing eddy currents in conductive materials to generate heat. Because the classification is specific to the heating method, it excludes furnaces that rely on electric resistance or infrared radiation. It is essential to distinguish these heavy-duty industrial units from domestic appliances, as the latter are classified based on their consumer-grade specifications and intended use in a household setting.

Codes often confused with 8514.20

Common mistake. A frequent misclassification occurs with HS code 8514.10, which is reserved for resistance-heated furnaces. While both are electric, the heating mechanism is fundamentally different. Another error involves HS code 8417, which covers industrial furnaces and ovens that are non-electric (such as gas or oil-fired). Furthermore, domestic induction cooktops must not be classified here; they belong under HS code 8516.60 as domestic cooking appliances.

Top exporters and importers of HS 851420 (the code used for induction furnace), 2025

In 2025, the largest exporter of HS 851420 (the code used for induction furnace) in UN Comtrade data was China, with 27% of world exports; the largest importer in UN Comtrade data was the United States, with 7.4% 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).

Questions about induction furnace

What is the HS code for Induction furnace?

The HS code for Induction furnace is 851420 (Furnaces and ovens; electric, for industrial or laboratory use, functioning by induction or dielectric loss). The HS code for industrial or laboratory induction furnaces is 8514.20.

How do I classify Induction furnace for customs?

Induction furnace is classified under HS code 851420 — Furnaces and ovens; electric, for industrial or laboratory use, functioning by induction or dielectric loss. This is a 6-digit subheading level code.

Are induction heaters for hardening classified here?

Generally, no. If the equipment is for heat treatment but is not a furnace or oven, it is classified under 8514.40.

Which countries are the top exporters of induction furnace (HS 851420)?

In 2025, the top exporters of HS 851420 (the code used for induction furnace) in UN Comtrade data were China ($159M, 27% of world exports), Germany ($88M) and Italy ($58M). World exports came to about $594M, adding countries' reported figures and partner-based estimates for those that did not report (UN Comtrade data). Countries that did not report 2025 data are estimated from partner records, which can understate them.

Which countries are the top importers of induction furnace (HS 851420)?

In 2025, the top importers of HS 851420 (the code used for induction furnace) in UN Comtrade data were the United States ($56M, 7.4% of world imports), Oman ($42M) and China ($42M). World imports came to about $750M, adding countries' reported figures and partner-based estimates for those that did not report (UN Comtrade data). Countries that did not report 2025 data are estimated from partner records, which can understate them.

Is the HS code for Induction furnace the same in all countries?

The base HS code 851420 for Induction furnace is internationally standardized for the first 6 digits across 200+ countries. Individual countries may add additional digits for national tariff lines and specific classifications.

What is the NCM code for induction furnace in Brazil?

Brazil splits HS 851420 into 3 NCM codes, so the right one for induction furnace depends on the product's details: 8514.20.11 (Industrial induction furnaces), 8514.20.19 (Other induction furnaces), 8514.20.20 (Dielectric loss furnaces).
