Import Tips
• Include normalization + temper heat treatment certification; improper processing voids boiler code compliance
• Customs often requires proof of 'seamless' via ultrasonic testing reports to distinguish from welded ERW pipes
• Label with 'For Boiler Use Only' to support specific suitability; vague descriptions risk general tube classification
