Import Tips
• Provide ASME certification and hydrostatic test reports demonstrating pressure containment capability
• Label pipes with material grade, dimensions, and heat number for traceability throughout supply chain
• Avoid bundling with fittings as sets, which could trigger classification as tube fittings under different headings
