Import Tips
• Verify API 5CT certification and mill test reports (MTRs) to confirm seamless construction and nonalloy steel composition for compliance
• Ensure accurate OD measurement documentation as exceeding 406.4 mm is key for this subheading; mismeasurement risks reclassification
• Obtain end-user declarations specifying oil/gas drilling use to avoid scrutiny under general pipe headings
