Import Tips
• Document stabilization heat treatment (carbide solution annealing) proving TP347H grade suitability
• Ship vertical in racks to prevent buckling; horizontal stacking risks ovality beyond API tolerances
• Cross-reference with ASTM A312 for seamless equivalents if manufacturing disputed during entry
