Product classification
HS code for Wafer 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 wafer furnace under HS 8514.19
Wafer furnaces used in the semiconductor industry are classified under HS code 8514.19. This classification is based on the primary function of the equipment as an industrial electric furnace and its specific heating method. Chapter 85 covers electrical machinery and equipment. Heading 8514 specifically covers industrial or laboratory electric furnaces and ovens. Subheading 8514.19 identifies resistance-heated furnaces and ovens, excluding hot isostatic presses, that are designed for the manufacture of semiconductor devices on semiconductor wafers. These machines are critical in the fabrication process, used for high-temperature operations such as dopant diffusion, thermal oxidation, and annealing. The classification under 8514.19 is preferred over more general machinery headings because it specifically describes the electrical heating mechanism and the specialized industrial application within the semiconductor sector. The equipment must be electrically operated and utilize resistance heating elements to qualify for this specific code.

Codes often confused with 8514.19
Common mistake. Wafer furnaces are often confused with HS code 8486.10 or 8486.20. While heading 8486 covers machines for the manufacture of semiconductors, the Explanatory Notes for heading 8514 specifically include electric furnaces used for these purposes. Another common misclassification is 8514.31, which is reserved for electron beam furnaces. If the furnace uses induction or dielectric heating instead of resistance heating, it should be classified under 8514.20. It is vital to verify the heating method before assigning the code.
Top exporters and importers of HS 851419 (the code used for wafer furnace), 2025
In 2025, the largest exporter of HS 851419 (the code used for wafer 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 wafer 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 wafer furnace
What is the HS code for Wafer furnace?
The HS code for Wafer 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 resistance-heated electric furnaces used for semiconductor wafer manufacturing is 8514.19.
How do I classify Wafer furnace for customs?
Wafer 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.
Does this code include gas-fired furnaces?
No, gas-fired or other non-electric industrial furnaces are classified under heading 8417. HS code 8514.19 is strictly for electric resistance-heated equipment.
Which countries are the top exporters of wafer furnace (HS 851419)?
In 2025, the top exporters of HS 851419 (the code used for wafer furnace) in UN Comtrade data were China ($847M, 31% of world exports), Italy ($483M) and Germany ($455M). World exports came to about $2.7B, adding countries' reported figures and partner-based estimates for those that did not report (UN Comtrade data).
