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
