HS code for Barometer: 9025.80
Hydrometers and similar floating instruments, barometers, hygrometers, psychrometers, thermometers, pyrometers, recording or not, any combination of these instruments (excluding thermometers and barometers not combined with other instruments).
Classification of barometer under HS 9025.80
Barometers are classified under HS code 9025.80. This classification falls within Chapter 90, which covers optical, photographic, cinematographic, measuring, checking, precision, medical or surgical instruments and apparatus. Heading 9025 specifically includes hydrometers, thermometers, pyrometers, barometers, hygrometers, and psychrometers. The subheading 9025.80 is the residual category for 'Other instruments' in this group, which encompasses barometers whether they are mechanical (aneroid) or electronic. The primary function of a barometer is to measure atmospheric pressure for meteorological purposes or altitude determination. While the heading description sometimes mentions combinations, a standalone barometer is classified here because it is a distinct instrument type listed in the heading text. The classification remains 9025.80 regardless of whether the instrument is a recording type (barograph) or a simple indicating type, provided it is not part of a more complex navigational system classified in 9014.

Codes often confused with 9025.80
Common mistake. Barometers are frequently misclassified under 9026.20, which covers instruments for measuring or checking the pressure of liquids or gases. The key distinction is that 9026 instruments measure pressure in closed systems (like a tire or a pipe), while 9025 instruments measure ambient atmospheric pressure. They may also be confused with 9014.10 (Direction finding compasses) or 9014.20 (Aeronautical instruments) if the barometer is specifically designed for aircraft use as an altimeter.
Top exporters and importers of HS 902580 (the code used for barometer), 2025
In 2025, the largest exporter of HS 902580 (the code used for barometer) in UN Comtrade data was China, with 17% of world exports; the largest importer in UN Comtrade data was the United States, with 15% 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).

Questions about barometer
What is the HS code for Barometer?
The HS code for Barometer is 902580 (Hydrometers and similar floating instruments, barometers, hygrometers, psychrometers, thermometers, pyrometers; recording or not, any combination of these instruments (excluding thermometers and barometers not combined with other instruments)). The HS code for a standard barometer is 9025.80.
How do I classify Barometer for customs?
Barometer is classified under HS code 902580 — Hydrometers and similar floating instruments, barometers, hygrometers, psychrometers, thermometers, pyrometers; recording or not, any combination of these instruments (excluding thermometers and barometers not combined with other instruments). This is a 6-digit subheading level code.
Does this code include digital weather stations?
If the device combines a barometer with a thermometer and hygrometer, it is still classified under 9025.80 as a combination of instruments from heading 9025.
Which countries are the top exporters of barometer (HS 902580)?
