Import Tips
• Verify API 5L certification and mill test reports (MTRs) to confirm nonalloy steel composition and longitudinal welding
• Ensure external diameter >406.4mm is documented; common pitfall is misclassification as smaller diameter pipes
• Provide end-user statements proving oil/gas pipeline use to avoid reclassification as general tubes
