HS code for Weather station: 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 weather station under HS 9025.80
A weather station is classified under HS code 9025.80. This code is designated for instruments such as hydrometers, barometers, hygrometers, and psychrometers, as well as any combination of these instruments. Weather stations typically integrate multiple sensors to measure atmospheric pressure, humidity, and temperature. According to the Chapter 90 notes and the General Interpretative Rules, when a device consists of two or more measuring instruments from heading 9025, it is classified under the sub-heading for "other instruments" or combinations, which is 9025.80. This classification applies to both traditional analog weather stations (often mounted on wood or plastic) and modern digital weather stations that use electronic sensors to transmit data to a display console. The essential character of the product is a multi-functional meteorological tool, which fits the description of combined instruments under this specific heading.

Codes often confused with 9025.80
Common mistake. Weather stations are often misclassified under HS code 9025.19 (thermometers) or 9025.80.10 (barometers) if the user only identifies one function. However, if the device combines these functions, 9025.80 is the correct collective code. Another error is using HS code 8543.70, which covers electrical machines and apparatus with individual functions. Because the primary purpose is measurement and meteorology, Chapter 90 takes precedence over Chapter 85. Additionally, if the station includes an anemometer (wind speed) as its primary component, some might look at 9026, but integrated stations remain in 9025.80.
Top exporters and importers of HS 902580 (the code used for weather station), 2025
In 2025, the largest exporter of HS 902580 (the code used for weather station) 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 weather station
What is the HS code for Weather station?
The HS code for Weather station 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 weather station is 9025.80, covering combinations of thermometers, barometers, and hygrometers.
How do I classify Weather station for customs?
Weather station 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 the HS code change if the weather station is digital?
No, both digital and analog integrated weather stations are classified under 9025.80, provided they combine multiple meteorological measuring functions.
Which countries are the top exporters of weather station (HS 902580)?
In 2025, the top exporters of HS 902580 (the code used for weather station) in UN Comtrade data were China ($282M, 17% of world exports), the United States ($199M) and Germany ($162M). World exports came to about $1.6B, 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.
