Import Tips

• Verify API 5CT certification and provide mill test reports (MTRs) to confirm seamless stainless steel composition and compliance with oilfield standards

• Ensure accurate measurement of outside diameter to avoid misclassification; common pitfall is confusing with welded pipes under Chapter 73 headings

• Declare end-use as oil/gas drilling explicitly to prevent reclassification as general mechanical tubing
