Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If standard non-proportional hydraulic valves
More specific subheading exists but this is 'other'; check if it fits exactly.
If as engine hydraulic components
Engine parts classified in 8412 if for vehicle/ engine transmissions.
If valve blocks/solenoids sold separately
Individual parts vs assembled transmission valves classified differently.
