Product classification
HS code for Glass thermometer: 9025.11
Thermometers and pyrometers, liquid filled, for direct reading, not combined with other instruments.
Classification of glass thermometer under HS 9025.11
Glass thermometers are classified under HS code 9025.11. This code falls within Chapter 90, which encompasses optical, photographic, cinematographic, measuring, checking, precision, medical or surgical instruments and apparatus. Heading 9025 specifically covers hydrometers, thermometers, pyrometers, barometers, hygrometers, and psychrometers. The subheading 9025.11 is reserved for thermometers and pyrometers that are liquid-filled for direct reading and are not combined with other instruments. This typically includes traditional mercury or alcohol-filled glass thermometers used in laboratories, clinical settings, or household environments. The classification is determined by the functional mechanism (liquid expansion) and the material of the housing (glass), as well as the fact that the instrument is standalone rather than integrated into a larger machine. The direct-reading nature of the device is a critical factor for this specific subheading.

Codes often confused with 9025.11
Common mistake. Glass thermometers are often misclassified under 9025.19, which is the residual category for "other" thermometers, including digital or electronic versions. Another common error is using 7017, which covers laboratory, hygienic, or pharmaceutical glassware. While a thermometer is made of glass and used in a lab, its function as a measuring instrument gives it specificity under 9025. Additionally, if the thermometer is combined with a barometer, it must be classified under 9025.80.
Top exporters and importers of HS 902511 (the code used for glass thermometer), 2025

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).
