Import Tips
• Include hydrostatic test certificates and chemical analysis reports to prove alloy content and suitability for sour gas service
• Label pipes clearly with grade markings and dimensions to facilitate customs verification as line pipe
• Avoid common pitfalls by distinguishing from drill pipe, which requires different end-use declarations
