Product classification
HS code for Laboratory 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 laboratory furnace under HS 8514.19
Laboratory furnaces that utilize resistance heating are classified under HS code 8514.19. These devices generate heat by passing an electric current through resistive elements, a method that allows for the precise temperature control and high-temperature capabilities required in scientific research and material testing. Common examples include muffle furnaces used for ashing samples and tube furnaces used for chemical vapor deposition or annealing. The classification 8514.19 is a residual category for resistance-heated furnaces and ovens that are not specifically designed for the manufacture of semiconductor devices. The primary factors for this classification are the use of electricity as the power source, the resistance heating mechanism, and the intended use in an industrial or laboratory setting. This distinguishes them from non-electric furnaces found in Chapter 84 and other types of electric heating equipment like induction furnaces.

Codes often confused with 8514.19
Common mistake. This code is often confused with 8514.39 (other electric ovens) or 8417 (industrial or laboratory furnaces and ovens, non-electric). The primary distinction is the heating method (resistance) and the power source (electric). Furthermore, furnaces specifically for semiconductor production are classified under 8514.11, so 8514.19 serves as the category for general-purpose resistance-heated units.
Top exporters and importers of HS 851419 (the code used for laboratory furnace), 2025
In 2025, the largest exporter of HS 851419 (the code used for laboratory 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.

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 laboratory furnace
What is the HS code for Laboratory furnace?
The HS code for Laboratory 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). Resistance-heated laboratory furnaces are classified under HS code 8514.19.
How do I classify Laboratory furnace for customs?
Laboratory 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.
What is the difference between a furnace and an oven in the HS?
Generally, furnaces (8514) reach higher temperatures for metallurgical or chemical changes, while ovens (8419 or 8514) are for lower-temperature drying, but the HS often groups them by heating method rather than just temperature.
Which countries are the top exporters of laboratory furnace (HS 851419)?
In 2025, the top exporters of HS 851419 (the code used for laboratory 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). Countries that did not report 2025 data are estimated from partner records, which can understate them.
Which countries are the top importers of laboratory furnace (HS 851419)?
In 2025, the top importers of HS 851419 (the code used for laboratory furnace) in UN Comtrade data were China ($456M, 18% of world imports), the United States ($247M) and Vietnam (about $129M). World imports came to about $2.5B, 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.
Is the HS code for Laboratory furnace the same in all countries?
The base HS code 851419 for Laboratory furnace is internationally standardized for the first 6 digits across 200+ countries. Individual countries may add additional digits for national tariff lines and specific classifications.
What is the NCM code for laboratory furnace in Brazil?
In Brazil, laboratory furnace (HS 851419) is classified under NCM 8514.19.00.
