Import Tips
• Conduct metallurgical analysis if cast vs. forged to confirm nonalloy status; cast iron may require separate verification
• Include hydrostatic test reports (min 1.5x pressure rating) as proof of fitness for pressure piping service
• Avoid bulk packaging misclassification; retail-ready flanges need consumer packaging declarations
