Import Tips

Verify API 5L certification and provide mill test reports (MTRs) to confirm seamless stainless steel composition and specs

Measure outside diameter precisely; exceeding 114.3 mm shifts to 7304.11.00.40, potentially altering duties

Include end-use documentation proving oil/gas pipeline application to avoid reclassification as general tubing
