Import Tips
• Verify inside diameter measurement exceeds 360 mm with precise caliper documentation to avoid misclassification to smaller flange subheadings
• Provide mill test certificates confirming nonalloy steel composition (max 0.25% carbon) for customs valuation and anti-dumping checks
• Ensure markings for pressure rating (e.g
• ANSI 150#) to demonstrate compliance with ASME B16.5 standards
