Import Tips

• Verify API 5CT certification and provide mill test certificates (MTC) to confirm non-alloy steel composition and threaded specifications

• Ensure couplings match casing dimensions exactly; mismatched imports may face reclassification or delays at customs

• Include drilling end-use documentation to avoid misclassification as general steel tubes under 7306.30
