Import Tips
• Verify API 5CT certification and material test reports (MTRs) to confirm compliance with oilfield standards and avoid reclassification
• Include end-user declarations specifying drilling use to differentiate from general piping under Chapter 73
• Watch for common pitfalls like incorrect welding method documentation, which could shift to seamless tubing codes
