Import Tips
• Include hydrostatic test records (min 80% of minimum yield strength) as standard OCTG proof
• Label bundles with heat numbers traceable to MTCs; missing traceability triggers FDA-equivalent CBP holds
• For re-import after testing, file CF-7501 with proper 9801/9802 annotations to avoid double duties
