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
