Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If imported separately without pump-specific mounting
Standalone valves or regulators classify under dedicated valves chapter, not pump parts.
If for parts of other liquid pumps excluding reciprocating
Non-reciprocating pump subheading parts use the broader 'other' category.
