HS Code for Barometer

Barometers are classified under HS code 9025.80. This classification falls within Chapter 90, which covers optical, photographic, cinematographic, measuring, checking, precision, medical or surgical instruments and apparatus. Heading 9025 specifically includes hydrometers, thermometers, pyrometers, barometers, hygrometers, and psychrometers. The subheading 9025.80 is the residual category for 'Other instruments' in this group, which encompasses barometers whether they are mechanical (aneroid) or electronic. The primary function of a barometer is to measure atmospheric pressure for meteorological purposes or altitude determination. While the heading description sometimes mentions combinations, a standalone barometer is classified here because it is a distinct instrument type listed in the heading text. The classification remains 9025.80 regardless of whether the instrument is a recording type (barograph) or a simple indicating type, provided it is not part of a more complex navigational system classified in 9014.

Products Included

• Aneroid barometers
• Mercury barometers (Fortin type)
• Barographs (recording barometers)
• Digital barometers
• Altimeter barometers (non-aviation)

Common Misclassification

Barometers are frequently misclassified under 9026.20, which covers instruments for measuring or checking the pressure of liquids or gases. The key distinction is that 9026 instruments measure pressure in closed systems (like a tire or a pipe), while 9025 instruments measure ambient atmospheric pressure. They may also be confused with 9014.10 (Direction finding compasses) or 9014.20 (Aeronautical instruments) if the barometer is specifically designed for aircraft use as an altimeter.

FAQ

What is the HS code for Barometer?

The HS code for a standard barometer is 9025.80.

Does this code include digital weather stations?

If the device combines a barometer with a thermometer and hygrometer, it is still classified under 9025.80 as a combination of instruments from heading 9025.
