Import Tips
• API 5CT certification required for oil country tubular goods; without it, may classify as general pipe
• Measure wall thickness internally/externally as customs uses minimum values for thick-wall criteria
• Avoid bulk packaging mislabeled as OCTG if for general drilling, not premium connections
