Rigid Polypropylene Water Pipe from China

A rigid tube made from polypropylene polymer, designed for conveying potable water in plumbing systems. It falls under HTS 3917.22.00.00 as a rigid tube, pipe, or hose of polymers of propylene, where propylene monomers constitute 95% or more by weight. These pipes are valued for their chemical resistance and durability in pressure applications.

Import Tips

Verify propylene content exceeds 95% by weight via lab testing to meet subheading note (a)(1) for accurate classification

Provide material safety data sheets (MSDS) confirming rigidity and pressure ratings to avoid reclassification as flexible hoses

Note that fittings are excluded; import them separately under relevant subheadings to claim Free (C) rates if applicable
