Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If functioning as flexible PVC fittings rather than rigid frames
Flexible plastic fittings/pipes classify under heading 3917 if hose-like.
If imported with integral plastic gate as a unit
Complete plastic gate assemblies may use the more specific subheading if enumerated.
If equipped with mechanical valves or actuators
Valve-integrated frames shift to machinery appliances if controlling flow.
