Rigid Polyethylene Water Pipe from Japan
A rigid tube made from high-density polyethylene (HDPE) polymers of ethylene, used for underground water distribution systems. It falls under HTS 3917.21.00.00 as a rigid pipe composed primarily of ethylene polymers (95%+ by weight), designed for fluid conveyance without flexibility.

Import Tips
• Verify polymer composition meets 95% ethylene monomer requirement per subheading notes to avoid reclassification
• Provide material test certificates confirming rigidity and ethylene polymer content during customs entry
• Avoid common pitfalls like misdeclaring flexible HDPE as rigid, which shifts to 3917.31 or 3917.39
