Import Tips
• Verify API 5L certification and mill test reports (MTRs) for material grade compliance to avoid customs holds
• Ensure accurate measurement documentation for OD >406.4mm and wall ≥19mm; misclassification to thinner walls is common
• Obtain end-user certificates if for energy infrastructure to qualify for potential duty exemptions
