Import Tips
• Verify API 5CT certification and provide mill test reports (MTRs) confirming seamless production, chemical composition, and mechanical properties
• Ensure accurate measurement documentation for OD ≤114.3mm and wall thickness >9.5mm to avoid reclassification to thinner wall subheadings
• Comply with API Monogram or equivalent standards; common pitfall is incorrect country-of-melt declaration for steel origin rules
