Import Tips

• Verify API 5L certification and provide mill test reports (MTRs) to confirm alloy steel composition and seamless manufacturing process

• Ensure proper documentation of external diameter and wall thickness to match line pipe specifications and avoid misclassification as casing

• Comply with API standards and pressure ratings to prevent customs disputes on end-use for oil/gas pipelines
