Import Tips

• Verify seamless certification via mill test reports (MTRs) as welded pipes classify under Chapter 73 headings like 7306

• Measure exact OD and wall thickness to confirm 114.3-190.5 mm OD and ≥19 mm wall; small deviations shift to adjacent subheadings

• Include chemical composition analysis proving nonalloy steel (≤0.3% alloying elements) to avoid Chapter 72 alloy steel headings
