Import Tips
• Provide certification that the tube meets boiler-grade standards, such as ASTM A335 or ASME SA-335
• Declare the outside diameter and wall thickness accurately, as sizes over 38.1 mm may have different statistical codes
• Consult the CBSA for duty rates, and ensure the alloy composition is documented to avoid reclassification
