Import Tips

Verify API 5L certification and mill test reports (MTRs) to confirm compliance with oil/gas pipeline standards

Ensure proper documentation of chemical composition to prove nonalloy steel status (carbon content under 0.3%)

Avoid misclassification as casing by confirming it's not threaded or coupled for well drilling
