Product classification
HS code for Semiconductor furnace: 8514.19
Furnaces and ovens, electric, for industrial or laboratory use, resistance heated, other than hot isostatic presses, for the manufacture of semiconductor devices on semiconductor wafers.
Classification of semiconductor furnace under HS 8514.19
Semiconductor furnaces used for processes such as diffusion, oxidation, or annealing are classified under HS code 8514.19. Heading 8514 covers industrial or laboratory electric furnaces and ovens. Sub-heading 8514.19 specifically refers to resistance-heated furnaces that are not hot isostatic presses. While heading 8486 covers many semiconductor machines, certain electric furnaces used in the industry remain under 8514 if they are resistance-heated and used for the heat treatment of semiconductor wafers. The classification is determined by the heating method (electrical resistance) and the industrial application. These furnaces are critical for modifying the electrical properties of the semiconductor material through controlled thermal environments, often involving the introduction of dopant gases at high temperatures.

Codes often confused with 8514.19
Common mistake. Semiconductor furnaces are often misclassified under 8486.10, which is reserved for machines used to grow monocrystal boules (like Czochralski pullers). They may also be confused with 8514.20, which covers furnaces functioning by induction or dielectric loss. If the furnace is used for laboratory research rather than industrial production, it still falls under 8514, but the specific sub-heading depends on the heating technology. It is vital to distinguish these from 8417, which covers non-electric industrial furnaces.
Top exporters and importers of HS 851419 (the code used for semiconductor furnace), 2025
In 2025, the largest exporter of HS 851419 (the code used for semiconductor furnace) in UN Comtrade data was China, with 31% of world exports; the largest importer in UN Comtrade data was China, with 18% 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 851419, not only semiconductor furnace.

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. 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 semiconductor furnace
What is the HS code for Semiconductor furnace?
The HS code for Semiconductor furnace is 851419 (Furnaces and ovens; electric, for industrial or laboratory use, resistance heated; other than hot isostatic presses, for the manufacture of semiconductor devices on semiconductor wafers). The HS code for a resistance-heated industrial semiconductor furnace is 8514.19.
How do I classify Semiconductor furnace for customs?
Semiconductor furnace is classified under HS code 851419 — Furnaces and ovens; electric, for industrial or laboratory use, resistance heated; other than hot isostatic presses, for the manufacture of semiconductor devices on semiconductor wafers. This is a 6-digit subheading level code.
Is a diffusion furnace classified under 8486?
