HS code for Liquid level gauge: 9026.10

Instruments and apparatus, for measuring or checking the flow or level of liquids.

Classification of liquid level gauge under HS 9026.10

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.

Codes often confused with 9026.10

Common mistake. 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.

Top exporters and importers of HS 902610 (the code used for liquid level gauge), 2025

In 2025, the largest exporter of HS 902610 (the code used for liquid level gauge) 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.

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).

Questions about liquid level gauge

What is the HS code for Liquid level gauge?

The HS code for Liquid level gauge is 902610 (Instruments and apparatus; for measuring or checking the flow or level of liquids). The HS code for instruments used to measure or check the level of liquids is 9026.10.

How do I classify Liquid level gauge for customs?

Liquid level gauge is classified under HS code 902610 — Instruments and apparatus; for measuring or checking the flow or level of liquids. This is a 6-digit subheading level code.

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.

Which countries are the top exporters of liquid level gauge (HS 902610)?

In 2025, the top exporters of HS 902610 (the code used for liquid level gauge) in UN Comtrade data were Germany ($1.5B, 20% of world exports), the United States ($1.1B) and China ($703M). World exports came to about $7.4B, adding countries' reported figures and partner-based estimates for those that did not report (UN Comtrade data). Countries that did not report 2025 data are estimated from partner records, which can understate them.

Which countries are the top importers of liquid level gauge (HS 902610)?
