Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If for high-pressure superheaters
Tubes designed for >290 psi and temps >212°F classify as boiler tubes under 7304.51.
If furnace-butt welded
Welded boiler tubes use heading 7306, excluding seamless construction.
If as part of complete boiler assembly
Imported within finished boilers, shifts to Chapter 84 as pressure vessel parts.
