HS code for Liquid thermometer: 9025.11
Thermometers and pyrometers, liquid filled, for direct reading, not combined with other instruments.
Classification of liquid thermometer under HS 9025.11
Liquid-filled thermometers for direct reading are classified under HS code 9025.11. These instruments operate on the principle of thermal expansion, where a liquid—typically mercury, toluene, or colored alcohol—is contained within a graduated glass capillary tube. As the temperature changes, the liquid expands or contracts, and the temperature is read directly from the scale. To fall under this specific subheading, the thermometer must be "direct reading," meaning it does not require electronic components or a digital display to show the temperature. Furthermore, it must not be combined with other instruments, such as hygrometers or barometers; combined instruments are classified under HS code 9025.80. The classification follows GRI 1 and 6, as heading 9025 specifically covers thermometers, pyrometers, barometers, and hygrometers. Subheading 9025.11 is the most specific description for liquid-filled versions. This code includes a wide range of devices, from clinical mercury thermometers to household room thermometers and laboratory-grade glass thermometers, provided they meet the direct-reading and liquid-filled criteria.

Codes often confused with 9025.11
Common mistake. The most common misclassification is with electronic or digital thermometers, which fall under HS code 9025.19. Another common error is classifying them under HS code 9025.80 if they are mounted on a decorative base that includes a clock or a humidity sensor, as these are considered combined instruments.
Top exporters and importers of HS 902511 (the code used for liquid thermometer), 2025
In 2025, the largest exporter of HS 902511 (the code used for liquid thermometer) in UN Comtrade data was China, with 28% of world exports; the largest importer in UN Comtrade data was Germany, with 9.1% 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 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).
