Seamless Carbon Steel Boiler Tube OD 25mm from Canada
A seamless tube made from non-alloy steel with an outside diameter of 25mm, precision-engineered for use in high-pressure steam boilers. It falls under HTS 7304.39.0002 due to its circular cross-section, seamless construction, and suitability for boilers where pressure resistance is critical. The small diameter ensures efficient heat transfer in compact boiler designs.

Import Tips
• Verify seamless construction via mill test certificates to avoid misclassification as welded pipes under 7306
• Ensure documentation specifies boiler/superheater use and exact OD measurement under 38.1mm for statistical reporting
