Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If cold-drawn for precision
Cold-formed seamless pipes (wall ≤16 mm note applies differently) may go to 7305 if not drilling-specific.
If classified as drill pipe
Threaded and coupled for drilling rotation classifies as drill pipe under 7304.21.
If welded nonalloy with similar dims
Welded versions of same size/application move to welded casing in 7306.19.
