Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If seamless construction
Seamless pipes of nonalloy steel fall under heading 7304, regardless of diameter.
If external diameter 406.4 mm or less
Smaller diameter welded pipes are classified in 7306, not 7305.
If alloy steel material
Alloy steel versions (e.g., with chromium/molybdenum) shift to other subheadings in 7305.90.
