Import Tips
• Submit NACE MR0175 compliance certs for sour service alloys to support classification and safety standards
• Use calibrated tools for wall thickness verification; customs may inspect physically if discrepancies noted
• Label shipments clearly as 'unfinished oil well casing' to prevent confusion with line pipe under 7304.90
