Import Tips
• Provide end-user statements confirming superheater application to support classification
• Ensure tubes meet ASME SA-213 standards; include mill test certificates for customs validation
• Avoid pitting by declaring exact cold-rolling reduction percentage to differentiate from hot-finished tubes
