HS Code for Density meter

Density meters, specifically those used for measuring the physical properties of liquids or gases, are classified under HS code 9026.80. This heading is reserved for instruments and apparatus for measuring or checking variables of liquids or gases, such as flow, level, or pressure (though pressure has its own subheadings). A density meter in this context measures the mass per unit volume of a fluid, often using oscillating U-tube technology, ultrasonic sensors, or Coriolis effects. These instruments are typically integrated into industrial pipelines or used in laboratory settings to monitor the concentration or purity of a substance. The classification is determined by the device's function as a process control or measurement tool for fluid dynamics, distinguishing it from instruments that perform complex chemical analysis.

Products Included

• Digital density meters for liquid samples
• In-line process density meters
• Ultrasonic gas density meters
• Coriolis flow meters with density measurement capabilities
• Vibrating element density transducers
• Specific gravity meters for industrial fluids

Common Misclassification

The most frequent misclassification occurs with HS code 9025.11 or 9025.80, which covers hydrometers. While a hydrometer measures density, it is a specific type of floating instrument. Electronic or digital density meters belong in 9026.80. Another common error is using 9027.89 (optical densitometers). As noted in other guides, 9027 is for light-based analysis, while 9026 is for fluid variables.

FAQ

What is the HS code for a liquid density meter?

The standard HS code for electronic or industrial liquid density meters is 9026.80.

Does this code include portable hydrometers?

No, traditional glass hydrometers are classified under HS code 9025.80. Only electronic or mechanical instruments for fluid variables fall under 9026.80.
