Import Tips
• Specify exact API grade (P110) and connection type (e.g
• BTC, VAM) in commercial invoice to match customs entry
• Wall thickness must be certified >=12.7 mm; ultrasonic testing reports prevent disputes over measurement tolerances
• Avoid bulk packaging confusion—casing is typically shipped in lengths of 40-50 ft; declare as individual joints
