HS Code for Electricity meter shunts

Electricity meter shunts are classified under HS code 9028.90, which specifically covers parts and accessories for gas, liquid, or electricity supply or production meters. According to the General Rules of Interpretation (GRI) 1 and 6, classification is determined by the terms of the headings and any relative section or chapter notes. Since these shunts are specifically designed to function as components within an electricity meter to measure current by creating a low-resistance path, they are categorized as parts of the primary instrument rather than general-purpose electrical resistors. Chapter 90 of the Harmonized System is dedicated to optical, measuring, checking, and precision instruments. Within this chapter, heading 9028 focuses on supply or production meters. The subheading 9028.90 is the residual category for parts and accessories that do not constitute the meter itself but are essential for its operation or calibration. These components must be identifiable as being solely or principally for use with the meters of heading 9028 to qualify for this classification. The technical nature of the shunt, being a calibrated resistive element for measurement, ensures it remains within the scope of precision instrumentation parts.

Common Misclassification

A frequent error is classifying these items under HS code 8533, which covers electrical resistors. While a shunt is technically a resistor, Note 2(b) to Chapter 90 states that parts which are suitable for use solely or principally with a particular kind of machine or instrument are to be classified with those machines or instruments. Therefore, if the shunt is specifically designed for an electricity meter, 9028.90 takes precedence over the general resistor code 8533. Additionally, some importers mistakenly use 9030.33 for instruments and apparatus for measuring or checking voltage, but that code is for complete instruments, not the component parts of a supply meter.

FAQ

What is the HS code for electricity meter shunts?

The correct HS code for electricity meter shunts is 9028.90, as they are considered parts and accessories of electricity supply meters.

Are these shunts different from standard electrical resistors?

Yes, while they function as resistors, they are precision-calibrated components specifically designed for current measurement within a meter, which dictates their classification in Chapter 90 rather than Chapter 85.
