Import Tips

• Verify API 5L certification and mill test reports (MTRs) for compliance with pipeline standards; U.S. buyers often require these for DOT approval

• Ensure accurate diameter measurement and seamless confirmation via NDT reports to avoid misclassification to welded pipes in 7305

• Label with stainless steel grade (e.g

• 304/316) and provide country-of-melt documentation to meet Buy America provisions for infrastructure projects
