HS Code for Flow meter

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.

Products Included

• Electromagnetic flow meters for liquids
• Ultrasonic liquid flow meters
• Turbine flow meters
• Vortex flow meters for liquid applications
• Variable area flow meters (rotameters)

Common Misclassification

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.

FAQ

What is the HS code for a flow meter?

For measuring the flow of liquids, the HS code is 902610. For gases, it is 902680.

What is the difference between HS 9026 and HS 9028?

HS 9026 is for instantaneous flow measurement in industrial processes, while HS 9028 is for supply meters that measure total volume over time for utility billing.
