HS Code for Manometer

The classification of a manometer under HS code 9026.20 is determined by its primary function as an instrument for measuring or checking the pressure of liquids or gases. Heading 9026 specifically covers instruments and apparatus for measuring or checking the flow, level, pressure, or other variables of liquids or gases. Within this heading, subheading 9026.20 is reserved for pressure-related devices. These instruments operate on various physical principles, such as the displacement of a liquid column, the deformation of an elastic element like a Bourdon tube or diaphragm, or through electrical sensors that convert pressure into an electronic signal. Because manometers are precision instruments used for monitoring system states rather than atmospheric conditions, they fall squarely into this category. The classification remains consistent regardless of whether the device is analog or digital, provided it is designed for pressure measurement in pipes, tanks, or closed systems.

Products Included

Common Misclassification

Manometers are frequently confused with barometers, which are classified under HS code 9025.80. While both measure pressure, barometers are specifically designed for atmospheric pressure measurement in meteorological contexts. Another common error involves classifying electronic manometers under 9031.80, which covers other measuring or checking instruments. However, because 9026 specifically names pressure measurement, it takes precedence over the more general heading 9031. Additionally, flow meters (9026.10) are sometimes confused with manometers when the pressure drop is used to calculate flow, but the primary function of the device dictates the code.
