Import Tips
• Submit API 5CT MTRs and drift test reports; critical for proving casing specs without duty disputes
• Declare OD in mm (323.85) accurately—NPS approximations can lead to OD range errors
• Avoid bundling with couplings; separate entries prevent fitting classification under 7304.29 or 7307
