Import Tips
• 13Cr is martensitic stainless; verify if customs requires stainless steel treatment under 7304.29.10
• Corrosion test results (e.g
• NACE TM0177) essential for high-alloy grades in sour/CO2 service
• Mark pipes with grade, size, and manufacturer per API 5CT; faded markings cause inspection delays
