Import Tips
• Obtain API 5CT certification and mill test reports (MTRs) to verify seamless construction and alloy composition for customs compliance
• Declare exact OD, wall thickness, and steel grade on entry documents; mismatches lead to reclassification or penalties
• Ensure proper marking per API standards to avoid scrutiny under anti-dumping investigations on Chinese-origin pipe
