Import Tips
• Submit hydrotest and non-destructive examination (NDE) reports to prove compliance with API standards and avoid quality disputes
• Label pipes clearly with grade, size, and wall thickness for easy customs inspection and inventory matching
• Monitor Section 232 tariffs on steel; additional duties may apply regardless of HTS based on melt-and-pour rules
