Import Tips
• Verify seamless construction via mill test certificates to avoid misclassification as welded pipes under 7306
• Ensure wall thickness documentation exceeds 4 mm; common pitfall is measurement discrepancies leading to reclassification
• Comply with ASME standards for boiler tubes; provide material composition certs proving nonalloy steel content
