Import Tips
• Require manufacturer's IBR (Indian Boiler Regulation) or ASME certification for power plant applications
• Document heat treatment records (normalizing/quenching) to validate A105 mechanical properties
• Use NDT reports (UT/MT) for crack detection in large forgings during customs inspection
