HS Code 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)

HS code 9025.80 is the 6-digit subheading for 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). It is used for digital weather stations, thermo-hygrometers, recording barometers, psychrometers and density meters (hydrometers).

What HS 9025.80 covers

This category encompasses a sophisticated range of instruments designed to measure various atmospheric and liquid properties, often featuring recording capabilities or combining multiple measurement functions. It includes devices like comprehensive weather stations, multi-function environmental meters, and industrial process monitors. These instruments are critical for meteorology, agriculture, HVAC, food storage, and chemical industries, where precise environmental control, data logging, and integrated monitoring are essential. Importers are typically industrial suppliers, research institutions, and specialized distributors who require advanced monitoring solutions. Exporters are often manufacturers of precision scientific and industrial instrumentation. The trade in these goods supports critical infrastructure and quality control across numerous sectors globally, enabling better decision-making and operational efficiency.

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).
