HS Code for Gas meter diaphragms

Gas meter diaphragms are classified under HS code 902890. This code is part of Chapter 90 and specifically falls under the category of parts and accessories for the meters described in heading 9028. Since gas meters themselves are classified under 902810, their components, such as diaphragms, housings, and internal mechanisms, are grouped under the parts subheading 902890. The diaphragm is a critical component in positive displacement gas meters, moving back and forth as gas flows to drive the counting mechanism. For a product to be classified here, it must be identifiable as being solely or principally for use with a gas, liquid, or electricity meter. This classification is essential for manufacturers and repair services importing specific components rather than whole units.

Products Included

• Flexible diaphragms for gas meters
• Internal measuring units for gas meters
• Gas meter casings and housings
• Recording mechanisms for supply meters
• Calibrating components for gas meters

Common Misclassification

A common misclassification for gas meter diaphragms is HS code 401693, which covers gaskets, washers, and other seals of vulcanized rubber. If the diaphragm is made of rubber, it might be mistakenly placed there; however, because it is a specialized part of a meter, 902890 takes precedence. Another error is attempting to classify the part under the same code as the finished product (902810). Additionally, if the part is a general-purpose screw or bolt used in the meter, it would be classified according to its constituent material (e.g., Chapter 73 for steel) rather than as a meter part.

FAQ

What is the HS code for gas meter diaphragms?

The HS code for gas meter diaphragms, as parts of a gas meter, is 902890.

Can general rubber seals be classified under 902890?

No, only parts that are specifically designed for use with meters of heading 9028 are classified here. General-purpose seals are classified under 4016.
