Import Tips

• Obtain API 5CT Monogram License and provide mill test certificates (MTC) confirming chemical composition and mechanical properties for alloy steel

• Verify outside diameter (11.25-16 inches) and wall thickness measurements; common pitfall is misclassification due to imprecise OD specs

• Include ITP (Inspection and Test Plan) documentation and ensure threads match API standards to avoid customs holds
