Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If the pipe is longitudinally submerged arc welded (LSAW) rather than helical welded
Longitudinal SAW pipes are classified separately under 7305.11.00.
If the pipe is longitudinally welded by other processes (e.g., ERW)
Other longitudinal welding methods fall under 7305.12.00.
