Import Tips
• Use NACE MR0175 compliance certs for sour service pipes to validate alloy classification and fitness for oil/gas
• Avoid common pitfalls by specifying 'not for boiler/pressure vessel use' in invoices to prevent 73.04 shifts
• Batch imports by diameter/size for easier statistical reporting under Census Bureau requirements
