Import Tips

• Verify API 5CT certification and provide mill test certificates (MTC) showing chemical composition and mechanical properties for nonalloy steel

• Confirm exact OD measurement (244.5 mm falls within 215.9-285.8 mm range) and wall thickness <12.7 mm via caliper measurements for customs

• Include end-use declaration for oil/gas drilling to avoid reclassification as general pipe under 7304.19
