More Specific Codes
This product may fall under a more specific subheading:
Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If certain heavy wall specifications
Specific heavy wall drill pipe may have separate statistical breakout within alloy steel.
If for non-drilling pressure applications
If marketed for hydraulic cylinders rather than drilling, becomes other alloy steel tubes.
If cold-drawn precision versions
Precision cold-drawn drill pipe may classify under 7304.19 if tolerances exceed standard drill pipe specs.
