HS Code for Tachometer

Tachometers are classified under HS code 902920, which specifically covers speed indicators and tachometers, as well as stroboscopes. This classification is determined by the device's primary function: measuring the rotation speed of a shaft or disk, typically expressed in revolutions per minute (RPM). As part of Chapter 90, these instruments are categorized alongside other high-precision measuring, checking, and medical apparatus. The classification applies to a wide variety of technologies, including mechanical centrifugal types, electrical generators, and modern digital optical or laser-based sensors. Because the tachometer provides a rate of speed rather than a simple cumulative count of units, it is distinguished from basic revolution counters. Whether the device is integrated into a vehicle dashboard or used as a handheld industrial tool, it remains within this heading provided it is not specifically designed for aeronautical or navigational purposes, which might shift it to other specialized chapters.

Common Misclassification

Tachometers are frequently confused with revolution counters under HS code 902910. While both measure rotation, 902910 is for devices that simply count total revolutions (like a production counter), whereas 902920 is for devices that measure the speed of rotation. Additionally, tachometers for aircraft or marine navigation may be classified under 9014, and general electronic measuring instruments without a specific heading might be incorrectly placed in 903180.

FAQ

What is the HS code for Tachometer?

The primary HS code for a tachometer is 902920, which falls under the category of speed indicators and stroboscopes.

Is a speedometer classified under the same HS code?

Yes, speedometers used for land vehicles are also classified under HS code 902920, as they function as speed indicators.
