Import Tips
• Provide ASME SA213 certification to validate heat-resisting properties and seamless construction
• Declare exact outer diameter and wall thickness accurately to match 7304.59.60.00 specifications
• Watch for undervaluation pitfalls; heat-resisting alloys command higher duties than carbon steel equivalents
