Import Tips
• Obtain material test certificates (MTC) confirming alloy composition and ASME compliance to avoid reclassification
• Ensure end-user documentation proves suitability for boilers or heat exchangers, as general-purpose tubes fall elsewhere
• Verify wall thickness measurement ≥1.65 mm; thinner walls shift to other subheadings
