Import Tips & Compliance
• Certify coating thickness (minimum 0.04 inches bituminous) meets NSF/ANSI 61 for potable water contact
• Bundle pipes in production lots with matching heat numbers for traceability during customs exam
• Avoid reclassification by excluding pressure test data that might suggest non-soil pipe use
