This product may fall under a more specific subheading:
Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If the tool set is imported with liquid meters as a complete unit
The set could be considered part of the meter itself if sold together, rather than as a separate accessory.
If the tools are used for measuring or checking instruments beyond meters
If the set is not exclusively for supply meters, it may fall under measuring instruments.
If the torque wrench is a general-purpose hand tool
General-purpose tools are classified in Chapter 82, not as meter accessories.
