Import Tips
• Provide ASTM A106 or A53 grade certifications; mismatch in grade can lead to alloy reclassification
• Declare exact wall thickness from caliper measurements; over-tolerance claims common pitfall causing duty disputes
• For pressure-rated pipes, include design pressure calculations if end-use suggests boiler tube potential
