HS Code 9027.89 – Instruments and apparatus; for physical or chemical analysis, for measuring or checking viscosity, porosity, expansion, surface tension or quantities of heat, sound or light, exposure meters
HS code 9027.89 is the 6-digit subheading for instruments and apparatus, for physical or chemical analysis, for measuring or checking viscosity, porosity, expansion, surface tension or quantities of heat, sound or light, exposure meters. It is used for pH meters, conductivity meters, moisture analyzers, digital refractometers and exposure meters.
What HS 9027.89 covers
This broad 'other' category for physical or chemical analysis instruments covers a wide array of devices not specifically classified elsewhere within 9027, including exposure meters. These instruments are used across diverse sectors for quality control, research, and process monitoring, measuring specific gravity, pH, conductivity, moisture content, and various other physical or chemical parameters. They are essential in laboratories, manufacturing plants, environmental monitoring stations, and agricultural settings. Importers range from academic institutions and government agencies to industrial facilities and commercial enterprises. Exporters are often specialized manufacturers of niche analytical equipment. Versatility, application-specific design, and reliability are key characteristics that drive their international trade, supporting a vast array of scientific and industrial processes.

Codes often confused with 9027.89
Common mistake. This 'other' category is frequently confused with more specific analytical instruments (e.g., 9027.10, 9027.20, 9027.30) or even general laboratory equipment (8479.89) if its analytical function isn't clearly defined.
Top exporters and importers of HS code 902789, 2025
In 2025, the largest exporter of HS code 902789 in UN Comtrade data was the United States, with 21% of world exports; the largest importer in UN Comtrade data was the United States, with 13% 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).
