Import Tips
• Include hydrostatic pressure test certifications to prove rigidity and suitability as pressure pipe
• Label clearly as 'rigid polypropylene pipe' to distinguish from flexible hoses under 3917.31-3917.40
• Avoid common pitfall of undervaluing based on bulk import; use transaction value with supporting invoices
