Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If having threaded ends with mechanical couplings
Tubing with specific threaded connections for drilling is separated into its own subheading.
If for industrial applications not specific to oil/gas drilling
Non-drilling welded tubes of circular cross-section go to general precision tubing headings.
If imported as assembled parts of drilling rigs
Tube sections integral to drilling machinery may classify as parts of pumps or drilling equipment.
