Import Tips
• Confirm the U-bend radius and overall dimensions are within the specifications for heat exchanger tubes
• Provide the CBSA with the ASTM or ASME standard to which the tube was manufactured
• Ensure the tube is not classified as a part of a machine under Section XVI, which would change the tariff classification
