HS Code for Water meter impellers

Water meter impellers are classified under HS code 902890, which is designated for parts and accessories of gas, liquid, or electricity supply or production meters. The classification logic follows Note 2(b) to Chapter 90, which states that parts and accessories, if suitable for use solely or principally with a particular kind of machine, instrument, or apparatus, are to be classified with those machines. Since an impeller is a critical internal component designed specifically to rotate in response to water flow within a meter, it is classified as a part of the liquid meter (heading 9028). The impeller's rotation is proportional to the volume of water passing through the device, allowing for accurate measurement. These components are often made of specialized plastics, brass, or stainless steel to resist corrosion and wear over long periods of submerged operation. The classification applies regardless of the material composition, provided the item is identifiable as a part of a water meter. This excludes general-purpose bearings or screws which might be used in the assembly but are classified elsewhere according to their own specific headings.

Common Misclassification

A frequent misclassification occurs under HS code 841391, which covers parts of pumps for liquids. While impellers are used in pumps, a water meter impeller is a measuring component, not a fluid-moving component, placing it in Chapter 90 rather than Chapter 84. Additionally, some importers mistakenly use 392690 for plastic impellers, but Note 2(b) to Chapter 90 takes precedence over general plastic article headings when the part is clearly identifiable for use with a measuring instrument.

FAQ

What is the HS code for water meter impellers?

The HS code for water meter impellers is 902890, as they are considered essential parts of liquid supply or production meters.

Are plastic and metal impellers classified differently?

No, the material does not change the classification. As long as the impeller is a dedicated part for a water meter, it remains under 902890 regardless of whether it is made of polymer or metal.
