Product classification
HS code for Melting furnace: 8417.10
Furnaces and ovens, non-electric, for the roasting, melting or other heat-treatment of ores, pyrites or of metals, for industrial or laboratory use.
Classification of melting furnace under HS 8417.10
A melting furnace is classified under HS code 8417.10 because it is a non-electric industrial or laboratory furnace designed specifically for the roasting, melting, or other heat-treatment of ores, pyrites, or metals. The Harmonized System distinguishes between furnaces based on their energy source and their specific industrial application. Heading 8417 covers furnaces that utilize combustion (such as gas, oil, or coal) rather than electricity. The subheading 8417.10 is reserved for equipment used in metallurgical processes. This classification is determined by the machine's primary function: the thermal transformation of raw metallic materials or ores into a molten state or a chemically altered state (roasting). The machinery must be of an industrial or laboratory scale to qualify. If the furnace were used for different materials, such as bakery products or ceramics, it would fall under different subheadings within 8417. The technical distinction here is the absence of electrical heating elements as the primary heat source, which separates this category from the electrical machinery found in Chapter 85.

Codes often confused with 8417.10
Common mistake. The most frequent misclassification for a melting furnace is HS code 8514.10 or 8514.20. These codes are specifically for electric industrial or laboratory furnaces and ovens. If a furnace uses induction, dielectric loss, or electric resistance heating, it must be classified under 8514 regardless of its use in melting metal. Another common error is using 8419.89, which covers general machinery for the treatment of materials by a process involving a change of temperature. However, because 8417 is more specific to furnaces and ovens, it takes precedence over the more general heading 8419 according to GRI 3(a).
Top exporters and importers of HS 841710 (the code used for melting furnace), 2025
In 2025, the largest exporter of HS 841710 (the code used for melting furnace) in UN Comtrade data was China, with 35% of world exports; the largest importer in UN Comtrade data was India, 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 841710, not only melting 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 melting furnace
What is the HS code for Melting furnace?
The HS code for Melting furnace is 841710 (Furnaces and ovens; non-electric, for the roasting, melting or other heat-treatment of ores, pyrites or of metals, for industrial or laboratory use). The HS code for a non-electric industrial melting furnace used for metals or ores is 8417.10.
How do I classify Melting furnace for customs?
Melting furnace is classified under HS code 841710 — Furnaces and ovens; non-electric, for the roasting, melting or other heat-treatment of ores, pyrites or of metals, for industrial or laboratory use. This is a 6-digit subheading level code.
Does this code include electric induction furnaces?
No, electric induction furnaces are classified under HS code 8514.20, as they rely on electrical energy rather than combustion.
Which countries are the top exporters of melting furnace (HS 841710)?
In 2025, the top exporters of HS 841710 (the code used for melting furnace) in UN Comtrade data were China ($281M, 35% of world exports), Italy ($117M) and Germany ($81M). World exports came to about $810M, 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 melting furnace (HS 841710)?
In 2025, the top importers of HS 841710 (the code used for melting furnace) in UN Comtrade data were India ($262M, 23% of world imports), the United States ($101M) and Indonesia ($90M). World imports came to about $1.1B, 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.
