Product classification
HS code for Laboratory oven: 8419.89
Machinery, plant and laboratory equipment, for treating materials by change of temperature, other than for making hot drinks or cooking or heating food.
Classification of laboratory oven under HS 8419.89
Laboratory ovens are classified under HS code 8419.89. This heading covers machinery, plant, or laboratory equipment, whether or not electrically heated, for the treatment of materials by a process involving a change of temperature such as heating, cooking, roasting, distilling, rectifying, sterilizing, pasteurizing, steaming, drying, evaporating, vaporizing, condensing or cooling, other than machinery or plant of a kind used for domestic purposes. Subheading 8419.89 is the residual category for equipment not specifically named in the preceding subheadings of 8419. For laboratory use, these ovens are typically used for drying, tempering, or heat-treating samples. It is important to distinguish these from industrial furnaces. The classification depends on the primary function being the change of temperature for material processing rather than simple space heating or domestic food preparation. These units are designed for precision temperature control and uniformity, which is critical for scientific experiments, moisture analysis, and material testing. They are distinct from sterilizers, which have their own specific subheading within the same 8419 group.

Codes often confused with 8419.89
Common mistake. A frequent misclassification occurs with HS code 8514, which covers industrial or laboratory electric furnaces and ovens. The distinction lies in the heating method and temperature range; 8514 is generally for high-temperature melting or heat treatment using resistance, induction, or dielectric heating. Additionally, laboratory sterilizers are often incorrectly placed in 8419.89, but they should be classified under 8419.20 if they are specifically designed for sterilization.
Top exporters and importers of HS 841989 (the code used for laboratory oven), 2025
In 2025, the largest exporter of HS 841989 (the code used for laboratory oven) in UN Comtrade data was China, with 20% of world exports; the largest importer in UN Comtrade data was the United States, with 20% 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 841989, not only laboratory oven.

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. UN Comtrade records Taiwan as "Other Asia, not elsewhere specified". Saudi Arabia's exports under that code are left out: they are far too large to be trade with Taiwan, so mostly undisclosed partners. 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 oven
What is the HS code for Laboratory oven?
The HS code for Laboratory oven is 841989 (Machinery, plant and laboratory equipment; for treating materials by change of temperature, other than for making hot drinks or cooking or heating food). The standard HS code for a general-purpose laboratory oven used for drying or heating is 8419.89.
How do I classify Laboratory oven for customs?
Laboratory oven is classified under HS code 841989 — Machinery, plant and laboratory equipment; for treating materials by change of temperature, other than for making hot drinks or cooking or heating food. This is a 6-digit subheading level code.
When should I use HS code 8514 instead of 8419?
HS code 8514 should be used for electric furnaces and ovens that operate via induction or dielectric loss, or for high-temperature industrial furnaces used for processes like annealing or melting, rather than simple drying.
Which countries are the top exporters of laboratory oven (HS 841989)?
In 2025, the top exporters of HS 841989 (the code used for laboratory oven) in UN Comtrade data were China ($2.6B, 20% of world exports), Germany ($1.7B) and Taiwan (about $1.3B). World exports came to about $13.1B, adding countries' reported figures and partner-based estimates for those that did not report (UN Comtrade data).
