HS Code for Barometer sensors

Barometer sensors are classified under HS code 9025.90. This classification is determined by the status of the sensor as a part or accessory of the instruments found in heading 9025. Heading 9025 covers barometers, thermometers, and other meteorological instruments, and subheading 9025.90 is specifically designated for 'Parts and accessories' of these devices. A barometer sensor is a transducer that detects atmospheric pressure and converts it into an electrical signal. Under General Interpretative Rule 1 and Chapter 90 Note 2(b), parts that are suitable for use solely or principally with a particular kind of machine or instrument are classified with those machines or instruments. Since these sensors are the core sensing element of a barometer, they are classified as parts under 9025.90. This applies to both traditional mechanical sensing elements and modern MEMS (Micro-Electro-Mechanical Systems) barometric pressure sensor modules, provided they are identifiable as parts of a barometer.

Products Included

• Barometric pressure sensor modules
• MEMS barometer sensors
• Mercury tubes for barometers
• Aneroid capsules (sensing elements)
• Electronic sensing boards for digital barometers

Common Misclassification

Barometer sensors are often misclassified under 9025.80, which is the code for the finished instrument. A sensor alone is a part, not a complete barometer. They are also frequently confused with 9026.90 (Parts for general pressure gauges) or 8542.39 (Electronic integrated circuits). If the sensor is a simple IC chip without any housing or barometric-specific calibration circuitry, it might fall under 8542, but most modules intended for barometric use stay in 9025.90.

FAQ

What is the HS code for Barometer sensors?

The HS code for barometer sensors is 9025.90, as they are considered parts of barometers.

Are all pressure sensors classified here?

No, only those specifically designed for measuring atmospheric pressure (barometric) are in 9025.90. General industrial pressure sensors are usually in 9026.90.
