Product classification
HS code for Industrial 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 industrial furnace under HS 8417.10
Industrial furnaces that are non-electric are classified under HS code 8417.10. This classification is governed by the specific function of the equipment: the roasting, melting, or heat treatment of ores, pyrites, or metals. Heading 8417 covers non-electric industrial or laboratory furnaces and ovens, including incinerators. Subheading 8417.10 is the most specific category for metallurgical processes. The distinction here is twofold: the energy source must be non-electric (such as gas, oil, or coal), and the application must be related to metal or ore processing. This follows GRI 1, which prioritizes the terms of the headings and subheadings. These furnaces are foundational to the primary metal industries and foundries, where high-volume thermal processing is required.

Codes often confused with 8417.10
Common mistake. The most frequent misclassification occurs between 8417.10 and 8514.10. The primary difference is the heat source; if the furnace uses electric heating elements, it must be moved to Chapter 85. Another common error is using 8417.80, which is a residual category for 'other' non-electric furnaces like bakery ovens or cement kilns. If the furnace is specifically for metals or ores, 8417.10 takes precedence. Importers also occasionally confuse these with large industrial dryers classified under 8419.39, but if the process involves melting or roasting, 8417 is the correct heading.
Top exporters and importers of HS 841710 (the code used for industrial furnace), 2025
In 2025, the largest exporter of HS 841710 (the code used for industrial 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.

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 industrial furnace
What is the HS code for Industrial furnace?
The HS code for Industrial 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). For non-electric furnaces used in metal or ore treatment, the HS code is 8417.10.
How do I classify Industrial furnace for customs?
Industrial 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.
Can a gas-fired bakery oven be classified under 8417.10?
No, a gas-fired bakery oven would be classified under 8417.80, as 8417.10 is specifically reserved for ore and metal processing.
Which countries are the top exporters of industrial furnace (HS 841710)?
