Import Tips
• Include NACE MR0175/ISO 15156 certification for sour service to support material classification and quality compliance
• Document hydrostatic test results as proof of seamless integrity; customs may request for high-pressure pipe verification
• Beware of alloy content thresholds—pipes with excessive chromium may be reclassified as stainless
