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
