Import Tips
• Obtain Mill Test Certificates (MTC) verifying chemical composition and mechanical properties per API 5CT specs; ensure API monogram marking for customs verification
• Declare exact OD, wall thickness, and grade to avoid reclassification; common pitfall is misstating weight per foot leading to wrong statistical suffix
