Import Tips

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

• Confirm exact OD (285.8-406.4 mm) and wall thickness (<12.7 mm) measurements to avoid misclassification into thicker wall subheadings

• Include end-use declaration as oil/gas drilling casing to distinguish from structural pipes; watch for anti-dumping duties on certain alloy steel pipes
