HS Code for Liquid level gauge

Liquid level gauges are classified under HS code 9026.10, which covers instruments and apparatus for measuring or checking the flow or level of liquids. This classification falls under Chapter 90, which is dedicated to optical, photographic, cinematographic, measuring, checking, precision, medical, or surgical instruments. The specific subheading 9026.10 is determined by the functional application of the device: the quantification of the height, volume, or flow rate of a liquid within a tank, pipe, or vessel. These instruments can operate through various physical principles, including mechanical floats, ultrasonic waves, hydrostatic pressure, or electrical capacitance. As long as the primary purpose is the measurement or checking of the liquid level, the technological method used does not change the 9026.10 classification. This code is vital for industrial process control, automotive fuel monitoring, and environmental water management. It excludes instruments that not only measure but also automatically control the level, which are classified elsewhere.

Products Included

• Float-type liquid level indicators
• Ultrasonic liquid level sensors
• Hydrostatic level transmitters
• Magnetic level gauges
• Sight glasses with graduated scales

Common Misclassification

A frequent error is classifying these devices under HS code 9032.89, which is for automatic regulating or controlling instruments. If the gauge merely displays or transmits a level signal, it belongs in 9026.10; if it actively controls a valve or pump to maintain a level, it may fall under 9032. Another misclassification is 9025.80, which covers hydrometers; while these also interact with liquids, they measure density rather than level or flow.

FAQ

What is the HS code for liquid level gauge?

The HS code for instruments used to measure or check the level of liquids is 9026.10.

Are electronic level sensors included in 9026.10?

Yes, electronic sensors, including ultrasonic and radar-based level transmitters, are classified under 9026.10 as long as their function is measuring or checking liquid levels.
