Import Tips
• Provide detailed chemical composition analysis to confirm 'alloy steel' status (e.g
• >1.65% manganese or other alloys), as per Chapter 72/73 notes
• Use NDT (non-destructive testing) reports like ultrasonic or radiographic to demonstrate weld integrity for customs and safety compliance
• Coordinate with freight forwarders experienced in oversized oilfield cargo to handle permits for diameters exceeding standard container sizes
