Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If check valves functioning solely to prevent backflow
Dedicated check valve heading applies regardless of material if primary function matches.
If as components of unlisted wafer slicing saw machines
Parts of Chapter 84 semiconductor machines supersede standalone valve classification.
If flexible metal tubing with simple valve
Tube/pipe fittings of base metals classify under Chapter 83 if not full appliances.
