Import Tips

• Verify API 5CT certification and mill test reports (MTRs) to confirm seamless nonalloy steel composition and dimensions

• Ensure threading/coupling matches casing standards to avoid reclassification as unfinished pipes

• Common pitfall: incorrect wall thickness measurement leading to wrong subheading
