Products classified under HTS 3917.22.00.00
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.
Polypropylene Pressure Pipe SDR11
Rigid polypropylene pipe with standard dimension ratio 11, used for high-pressure water distribution. Classified in 3917.22.00.00 due to its rigid structure and propylene polymer composition exceeding 95% by weight. Ideal for municipal and irrigation systems.
Rigid PP Chemical Transfer Pipe
Rigid pipe extruded from polypropylene homopolymer for transporting corrosive chemicals in industrial plants. Meets HTS 3917.22.00.00 as a rigid tube of propylene polymers (≥95% propylene content). Offers excellent resistance to acids and bases.
PP Irrigation Mainline Pipe
Rigid polypropylene pipe for agricultural irrigation mains, with thick walls for burial installation. Falls under 3917.22.00.00 for rigid tubes of propylene polymers per subheading notes. UV-stabilized for outdoor durability.
Rigid Polypropylene Drain Pipe
Schedule 40 rigid polypropylene pipe used for drainage and sewer lines in construction. Classified in HTS 3917.22.00.00 as rigid tubes of propylene (95%+ monomer content). Corrosion-resistant alternative to PVC.
PP Lab Fume Hood Duct Pipe
Rigid polypropylene duct pipe for laboratory fume hood exhaust systems, resistant to acid vapors. HTS 3917.22.00.00 applies to its rigid tube form from propylene homopolymer. Used in chemical processing labs.
