Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If outside diameter over 406.4 mm
Larger OD casing moves to 7304.29.50 statistical suffix for bigger wellbore applications.
If imported as part of drilling rig assembly
If entered as completed drill pipe parts set, may classify under oilfield machinery parts in 8431.
If not specifically for oil/gas drilling
General seamless tubing outside drilling use falls under 7304.19, not dedicated casing 7304.29.

Import Tips & Compliance
• Include PSL-2 quality level certificates for P110 grade to meet API drilling standards during customs review
• Document thread type (e.g
• BTC) and coupling specs to confirm 'threaded or coupled' classification
• Avoid reclassification by providing dimensional caliper reports proving OD 244-406mm range
