Rigid Polypropylene Water Pipe
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.

Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If copolymer with less than 95% propylene monomers
Copolymers not meeting the 95% propylene threshold classify under 'other plastics' per subheading note (a)(4), based on predominant monomer.
If the hose includes attached fittings
Tubes with attached fittings qualify for Free (C) under heading 3917 per US note, shifting from general rigid tubes.
If imported as a finished plumbing component set rather than bulk pipe
Articles of plastics not specifically tubes may fall under other plastic articles if not meeting rigid tube definitions.

Import Tips & Compliance
• 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
