Import Tips

• Verify API 5L certification and mill test reports (MTRs) to confirm alloy steel composition and compliance with ASTM A671/A672 standards

• Provide detailed documentation on external diameter (>406.4 mm) and wall thickness to avoid misclassification as smaller pipes under 7306

• Check country-of-origin rules under USMCA or other FTAs, as alloy steel pipes often qualify for duty reductions if sourced from qualifying nations
