L80 Oilfield Tubing with Integral Coupling
L80 grade non-alloy steel tubing for oilfield casing applications, featuring welded seams and imported with integrally formed couplings. It qualifies for HTS 7306.29.60.10 as other tubing used in oil/gas drilling, providing structural support and isolation in wellbores. The design allows for pressurized fluid handling.

Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If casing rather than tubing
Larger diameter or specific wall thickness designates it as casing over tubing.
If threaded at both ends but no coupling
Tubing with threads but without attached couplings falls into 7307 for tube fittings.
If seamless non-alloy steel
Absence of welds shifts classification to seamless tubes in heading 7304.

Import Tips & Compliance
• Certify compliance with API 5CT for L80 properties like collapse resistance
• Bundle in protective caps for couplings during transit
• Avoid bulk packing that risks reclass as unfinished goods
