Import Tips
• Verify API 5L certification and mill test reports (MTRs) for compliance with energy sector standards
• Ensure accurate measurement of outside diameter to confirm >406.4 mm classification; mismeasurement leads to reclassification
• Provide end-use documentation proving oil/gas pipeline application to avoid duty shifts
