HS Code for Exhaust gas analyzer

Exhaust gas analyzers are classified under HS code 9027.10. This classification is situated within Chapter 90, which covers optical, measuring, checking, or precision instruments. Heading 9027 specifically pertains to instruments and apparatus for physical or chemical analysis. Subheading 9027.10 is dedicated to gas or smoke analysis apparatus. These devices are used to determine the chemical composition of exhaust gases from internal combustion engines, boilers, or industrial stacks. They operate based on various physical principles, such as infrared absorption, thermal conductivity, or electrochemical sensors. Because their primary function is the qualitative or quantitative analysis of gas components (such as Carbon Monoxide, Nitrogen Oxides, or Hydrocarbons), they are strictly classified here. This code applies to both portable handheld analyzers used by automotive technicians and large, stationary systems used in industrial environmental monitoring.

Products Included

• Automotive emission testers
• Infrared gas analyzers
• Smoke meters for diesel engines
• Flue gas analyzers for boilers
• CO2 and NOx sensors (as part of analysis systems)

Common Misclassification

Exhaust gas analyzers are sometimes misclassified under 9026, which covers instruments for measuring or checking the flow, level, or pressure of liquids or gases. However, 9026 does not cover chemical analysis. Another common error is 9031, which is a catch-all for measuring or checking instruments not specified elsewhere. Since gas analysis is specifically mentioned in 9027.10, it takes precedence over the general category of 9031.

FAQ

What is the HS code for an exhaust gas analyzer?

The HS code for an exhaust gas analyzer is 9027.10.

Does this code include oxygen sensors?

Individual oxygen sensors imported as vehicle parts are often classified under 9027.90 (parts) or 9027.10, but if they are simple electrical resistors, they might fall under 8533.
