Import Tips
• Verify the pipe's external diameter exceeds 406.4 mm and the weld is longitudinal for classification under 7305.31.00
• Provide material test certificates confirming the alloy steel grade and thermal fatigue resistance
• Check if the pipe requires CSA or other Canadian certification for power plant use
