HS code · 6-digit subheading
HS Code 9026.90 – Instruments and apparatus; parts and accessories for those measuring or checking the flow, level, pressure or other variables of liquids or gases (excluding those of heading no. 9014, 9015, 9028 or 9032)
HS code 9026.90 is the 6-digit subheading for instruments and apparatus, parts and accessories for those measuring or checking the flow, level, pressure or other variables of liquids or gases (excluding those of heading no. 9014, 9015, 9028 or 9032). It is used for flow meter impellers, pressure sensor diaphragms, level gauge floats, temperature transmitter housings and pH probe electrodes.
What HS 9026.90 covers
This HS code covers parts and accessories specifically designed for instruments and apparatus used to measure or check variables like flow, level, pressure, or other characteristics of liquids or gases. These components are critical in maintaining the functionality and accuracy of sophisticated industrial process control, environmental monitoring, and safety systems. Importers typically include manufacturing plants, oil and gas companies, water treatment facilities, and chemical processing industries that rely on precise measurement. Exporters are often specialized manufacturers of high-precision instrumentation and their spare parts. Key considerations in international trade for these items include material compatibility, calibration standards, and ensuring seamless integration into existing measurement systems to prevent downtime and maintain 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).
