HS code for Barometer sensors: 9025.90
Hydrometers and similar floating instruments, barometers, hygrometers, psychrometers, thermometers, pyrometers, recording or not, any combination of these instruments, parts and accessories.
Classification of barometer sensors under HS 9025.90
Barometer sensors are classified under HS code 9025.90. This classification is determined by the status of the sensor as a part or accessory of the instruments found in heading 9025. Heading 9025 covers barometers, thermometers, and other meteorological instruments, and subheading 9025.90 is specifically designated for 'Parts and accessories' of these devices. A barometer sensor is a transducer that detects atmospheric pressure and converts it into an electrical signal. Under General Interpretative Rule 1 and Chapter 90 Note 2(b), parts that are suitable for use solely or principally with a particular kind of machine or instrument are classified with those machines or instruments. Since these sensors are the core sensing element of a barometer, they are classified as parts under 9025.90. This applies to both traditional mechanical sensing elements and modern MEMS (Micro-Electro-Mechanical Systems) barometric pressure sensor modules, provided they are identifiable as parts of a barometer.

Codes often confused with 9025.90
Common mistake. Barometer sensors are often misclassified under 9025.80, which is the code for the finished instrument. A sensor alone is a part, not a complete barometer. They are also frequently confused with 9026.90 (Parts for general pressure gauges) or 8542.39 (Electronic integrated circuits). If the sensor is a simple IC chip without any housing or barometric-specific calibration circuitry, it might fall under 8542, but most modules intended for barometric use stay in 9025.90.
Top exporters and importers of HS 902590 (the code used for barometer sensors), 2025
In 2025, the largest exporter of HS 902590 (the code used for barometer sensors) in UN Comtrade data was Germany, with 11% of world exports; the largest importer in UN Comtrade data was China, with 11% 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 902590, not only barometer sensors.

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 sensors
What is the HS code for Barometer sensors?
The HS code for Barometer sensors is 902590 (Hydrometers and similar floating instruments, barometers, hygrometers, psychrometers, thermometers, pyrometers; recording or not, any combination of these instruments, parts and accessories). The HS code for barometer sensors is 9025.90, as they are considered parts of barometers.
How do I classify Barometer sensors for customs?
Barometer sensors is classified under HS code 902590 — Hydrometers and similar floating instruments, barometers, hygrometers, psychrometers, thermometers, pyrometers; recording or not, any combination of these instruments, parts and accessories. This is a 6-digit subheading level code.
Are all pressure sensors classified here?
No, only those specifically designed for measuring atmospheric pressure (barometric) are in 9025.90. General industrial pressure sensors are usually in 9026.90.
Which countries are the top exporters of barometer sensors (HS 902590)?
In 2025, the top exporters of HS 902590 (the code used for barometer sensors) in UN Comtrade data were Germany ($198M, 11% of world exports), China ($182M) and Japan ($170M). World exports came to about $1.8B, 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 barometer sensors (HS 902590)?
In 2025, the top importers of HS 902590 (the code used for barometer sensors) in UN Comtrade data were China ($192M, 11% of world imports), Japan ($116M) and the United States ($111M). World imports came to about $1.7B, 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.
Is the HS code for Barometer sensors the same in all countries?
The base HS code 902590 for Barometer sensors 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 barometer sensors in Brazil?
Brazil splits HS 902590 into 2 NCM codes, so the right one for barometer sensors depends on the product's details: 9025.90.10 (Parts and accessories of thermometers), 9025.90.90 (Parts and accessories of hydrometers and similar).
