Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If stainless steel cold-drawn for heat exchanger use
Stainless-specific subheading 7304.41 applies over general alloy steel for equivalent cold-formed tubes.
If hot-finished rather than cold-drawn/rolled
Hot-rolled or hot-drawn tubes of alloy steel use 7304.39, differentiated by forming process.
If assembled into complete heat exchanger units
Machinery classification takes precedence when tubes are incorporated into functional heat exchanger equipment.
