Import Tips
• Verify the 4340 steel composition (nickel 0.3% or more, chromium 0.3% or more, molybdenum 0.08% or more) to confirm it is 'other alloy steel'
• Ensure the purlin is not punched, drilled, or otherwise worked beyond hot-rolling
• Provide a certificate of analysis to the CBSA for smooth clearance
