Import Tips

• Verify seamless manufacturing certification and provide mill test reports confirming chemical composition and mechanical properties per ASTM standards

• Ensure dimensional compliance with outside diameter 114.3-190.5mm and wall thickness 12.7-19mm to avoid reclassification to adjacent subheadings

• Include end-use documentation if for pressure applications to confirm appropriate pressure ratings and safety compliance
