Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If having wall thickness 12.7 mm up to 16 mm
Medium wall thickness casings have dedicated subheadings for graduated strength categories.
If used as welded line pipe
End-use as pipeline rather than drilling casing shifts to line pipe classifications.
If imported with proprietary coatings for non-drilling use
Surface-treated articles not primarily for oilfield may classify as other steel articles.

Import Tips & Compliance
• Ensure thread type (e.g
• BTC, EUE) is documented but does not trigger fitting classification if couplings absent
• Batch test for alloy elements (Cr, Mo, Ni) as customs may sample for proper 7304.29 heading placement
• Declare precise grade (T95) and API monogram to facilitate faster release from oilfield specialists at ports
