Import Tips

• Obtain API 5CT certification documentation to verify seamless construction and alloy steel composition meeting L80/13CR specs

• Provide mill test certificates (MTC) confirming wall thickness ≥12.7 mm and exact outside diameter under 215.9 mm for customs classification

• Avoid misclassification by specifying 'casing for oil/gas drilling' on commercial invoice; watch for overages in OD measurements
