Import Tips
• Include NACE MR0175/ISO 15156 certification proving H2S resistance for sour service applications
• Wall thickness must be drift-tested and documented; customs may require ultrasonic thickness verification
• Specify exact grade (13Cr, Super 13Cr) in commercial invoice to match HTS material requirements
