Import Tips

• Verify seamless certification via mill test reports (MTRs) to confirm classification under 7304, avoiding misclassification as welded pipes in 7306

• Ensure API 5L compliance documentation for oil/gas end-use; provide hydrostatic test results to customs for duty-free claims if applicable

• Watch for wall thickness measurement disputes—use precise caliper readings under 12.7 mm to prevent reclassification to thicker subheadings
