Import Tips
• Obtain API 5CT Monogram License and mill test certificates (MTC) verifying chemical composition and mechanical properties
• Provide ITP (Inspection and Test Plan) documentation; third-party inspection by bodies like Lloyd's Register is standard
• Confirm exact OD measurement (13-3/8" = 339.7mm) falls within 285.8-406.4mm range to avoid reclassification
