HS Code for Ohmmeter

An ohmmeter is classified under HS code 9030.33, which pertains to instruments and apparatus for measuring or checking electrical quantities. Chapter 90 of the Harmonized System covers optical, photographic, cinematographic, measuring, checking, precision, medical, or surgical instruments. Within this chapter, heading 9030 is dedicated to oscilloscopes, spectrum analyzers, and other instruments for measuring or checking electrical quantities. Subheading 9030.33 specifically identifies instruments for measuring voltage, current, resistance, or power that do not have a recording device and are not multimeters. The classification is driven by the device's specific function—measuring electrical resistance—and the absence of integrated features like data recording or multi-functionality. If the device were capable of measuring multiple parameters like voltage and current simultaneously, it would be classified as a multimeter. The technical distinction between a recording and non-recording device is also critical; a recording device would include internal memory or a paper chart output to track measurements over time.

Products Included

• Digital ohmmeters for resistance testing
• Analog resistance meters
• Micro-ohmmeters for low resistance measurement
• Insulation resistance testers (megohmmeters)
• Milliohmmeters for precision laboratory use

Common Misclassification

The most frequent misclassification occurs with HS code 9030.31, which is reserved for multimeters. A multimeter can measure resistance, but because it also measures voltage and current, it is more specific than an ohmmeter. Another common error is using HS code 9030.39, which is for instruments that include a recording device. If the ohmmeter has a built-in data logger, it must be moved to 9030.39.

FAQ

What is the HS code for an ohmmeter?

The standard HS code for a dedicated ohmmeter without a recording device is 9030.33.

Does this code include multimeters that measure resistance?

No, multimeters are classified under HS code 9030.31 because they are multi-functional instruments capable of measuring more than just resistance.
