Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If flexible polyurethane hose
Flexible polyurethane conveyance items are in 3917.33 for other plastic flexible types.
If used as sanitary ware like bath fittings
Plastic sanitary articles (e.g., rigid pipe sections for baths) shift to Chapter 39 heading 3922.
If rigid pipes of propylene polymers
Propylene-dominant (>95%) rigid pipes go to 3917.23 per polymer naming rules.
