Import Tips
• Verify API 5CT certification and provide mill test reports (MTRs) confirming seamless production, grade J55, exact OD/wall specs to avoid reclassification
• Ensure proper documentation of threaded/coupled ends and nonalloy steel composition; common pitfall is misstating wall thickness leading to duty shifts
• Comply with API standards and US oilfield regulations; label with heat number for traceability
