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
