Import Tips

• Obtain API 5CT Monogram License and mill test certificates (MTC) verifying chemical composition and mechanical properties

• Confirm exact OD (215.9-285.8 mm) and wall thickness (>=12.7 mm) measurements to avoid reclassification to thinner wall subheadings

• Include ITP (Inspection Test Plan) documentation; common pitfall is missing heat treatment records for alloy steel grades
