HS code for E-beam furnace: 8514.31
Furnaces and ovens, electric, for industrial or laboratory use, other than those functioning by induction, dielectric loss or resistance heated, electron beam furnaces.
Classification of E-beam furnace under HS 8514.31
The classification of electron beam (E-beam) furnaces under HS code 8514.31 is determined by their specific heating mechanism and industrial application. Heading 8514 covers industrial or laboratory electric furnaces and ovens. Subheading 8514.31 specifically isolates those functioning by electron beam. Unlike resistance-heated or induction furnaces, E-beam furnaces utilize a high-energy stream of electrons to melt or treat materials, typically in a vacuum environment to prevent oxidation and allow for precise temperature control. This classification applies regardless of whether the furnace is used for melting, refining, or coating processes, provided the primary energy source for heating is an electron beam. The technical distinction lies in the use of an electron gun as the heat source, which allows for extremely high power densities and the processing of refractory metals that are difficult to handle with conventional heating methods. These units are essential in metallurgy for producing high-purity metals and alloys, as the vacuum environment and concentrated energy source ensure minimal contamination during the melting process.

Codes often confused with 8514.31
Common mistake. E-beam furnaces are frequently misclassified under HS code 8514.10, which covers resistance-heated furnaces, or HS code 8514.20, which covers induction or dielectric furnaces. The confusion often arises because all these units are electric industrial furnaces. However, the Harmonized System prioritizes the specific method of heating. If the heat is generated by an electron beam, 8514.31 is the mandatory code. Another common error is using 8486.20 for machines used in semiconductor manufacturing; while some E-beam systems are used in chip making, general-purpose industrial furnaces remain in 8514. Importers must verify the primary heating technology to avoid using the generic "other" categories in 8514.39.
Top exporters and importers of HS 851431 (the code used for E-beam furnace), 2025
In 2025, the largest exporter of HS 851431 (the code used for E-beam furnace) in UN Comtrade data was Germany, with 48% of world exports; the largest importer in UN Comtrade data was the United States, with 23% 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 851431, not only E-beam furnace.

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 E-beam furnace
What is the HS code for E-beam furnace?
The HS code for E-beam furnace is 851431 (Furnaces and ovens; electric, for industrial or laboratory use, other than those functioning by induction, dielectric loss or resistance heated, electron beam furnaces). The primary HS code for an electron beam furnace used in industrial or laboratory settings is 8514.31. This code specifically identifies the electron beam heating technology.
How do I classify E-beam furnace for customs?
E-beam furnace is classified under HS code 851431 — Furnaces and ovens; electric, for industrial or laboratory use, other than those functioning by induction, dielectric loss or resistance heated, electron beam furnaces. This is a 6-digit subheading level code.
Does this code include E-beam welding machines?
While E-beam welding machines share technology with E-beam furnaces, they are often classified under 8515.80 if their primary function is welding rather than general heating or melting. However, if the unit is designed as a furnace for heat treatment, 8514.31 applies.
Which countries are the top exporters of E-beam furnace (HS 851431)?
In 2025, the top exporters of HS 851431 (the code used for E-beam furnace) in UN Comtrade data were Germany ($43M, 48% of world exports), Singapore ($11M) and Malaysia ($11M). World exports came to about $91M, 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 E-beam furnace (HS 851431)?
In 2025, the top importers of HS 851431 (the code used for E-beam furnace) in UN Comtrade data were the United States ($23M, 23% of world imports), Malaysia ($18M) and Singapore ($11M). World imports came to about $103M, 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.
