Import Tips
• Verify API 5CT certification and provide mill test certificates (MTC) to confirm seamless construction and non-alloy steel composition
• Check outside diameter ≤114.3 mm and wall thickness ≤9.5 mm measurements; non-conformance may shift to other subheadings
• Include end-user declaration specifying oil/gas drilling use to avoid reclassification as general pipe under 7304.19
