3917.40.00.50 - Other

This HTS classification covers fittings for tubes, pipes, and hoses made of plastics, specifically those used in plumbing applications that are not designed for pressure-rated systems, such as Drain, Waste, and Vent (DWV) applications. These fittings are intended for non-pressurized fluid conveyance and drainage within a building's plumbing infrastructure. Examples include elbows, couplings, traps, and connectors used in sanitary drainage systems.

This category, "Other," is distinct from its sibling categories that specify fittings made from particular plastics. Whereas 3917.40.00.20 specifically classifies fittings of polyvinyl chloride (PVC) and 3917.40.00.30 covers fittings of acrylonitrile-butadiene-styrene (ABS), this "Other" category encompasses fittings made from any other plastic materials not otherwise specified. This allows for the classification of a wide range of plastic plumbing fittings composed of materials such as polypropylene, polyethylene, or other copolymers.

As this is a leaf node, there are no further subdivisions. The classification is determined by the material of the fitting if it is not PVC or ABS. Importers should carefully identify the plastic composition of their plumbing fittings to ensure accurate classification under the correct sub-heading.
