Import Tips
• Provide DNV-OS-F101 or API RP 2RD design verification for offshore certification; essential for BOEM lease compliance
• Declare exact wall thickness and yield strength to distinguish from smaller OCTG; mismeasurement leads to frequent CBP queries
• Bundle with coating specs (e.g
• 3LPE) but classify pipe body separately unless integral to tariff description
