Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If outside diameter ≤114.3 mm
Narrower OD casing or tubing falls under smaller diameter subheadings in 7304.29.
If welded and used specifically for oil/gas drilling
Welded OCTG casing classifies in 7306 based on weld seam presence, despite similar use.
If imported as parts of oil drilling rigs
End-use integration into Chapter 84 mining/drilling machinery reclassifies from base pipes.

Import Tips & Compliance
• 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
