Import Tips
• Verify API 5DP/5CT certification and include mill test certificates (MTC) in documentation
• Confirm alloy steel composition meets ASTM A335 or equivalent standards; carbon steel shifts to 7304.19
• Check wall thickness measurement method (ultrasonic vs caliper) to avoid misclassification over 9.5mm
