Product classification
HS code for Flow meter: 9026.10
Instruments and apparatus, for measuring or checking the flow or level of liquids.
Classification of flow meter under HS 9026.10
Flow meters for liquids are classified under HS code 902610. This code is part of Chapter 90, which encompasses optical, photographic, measuring, checking, and medical instruments. Heading 9026 specifically covers instruments and apparatus for measuring or checking the flow, level, pressure, or other variables of liquids or gases. Subheading 902610 is dedicated to those instruments that measure the flow or level of liquids. These devices are critical in industrial automation, chemical processing, and water management. The classification applies to the complete instrument, which typically includes a sensor to detect the liquid movement and a transmitter or display to provide the reading. Whether the device uses mechanical, ultrasonic, electromagnetic, or Coriolis principles, it remains under 902610 as long as it is measuring liquid flow in a process environment.

Codes often confused with 9026.10
Common mistake. The most frequent misclassification is with HS code 902820, which covers liquid supply or production meters. The distinction is that 9028 is for 'totalizing' meters used for billing or commercial supply (like a residential water meter), whereas 9026 is for process measurement and control. Another error is using 902680, which is for instruments measuring the flow of gases. If a meter is designed for both or specifically for gas, 902610 is incorrect. Finally, pressure-only gauges should be classified under 902620.
Top exporters and importers of HS 902610 (the code used for flow meter), 2025
In 2025, the largest exporter of HS 902610 (the code used for flow meter) in UN Comtrade data was Germany, with 20% of world exports; the largest importer in UN Comtrade data was the United States, with 14% 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 902610, not only flow meter.

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).
