Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If imported individually
Separate pipe fittings classify under Chapter 73 iron/steel fittings without engine context.
If copper alloy versions
Copper propellant fittings fall under Chapter 74 when material predominant.
If fuel line components
Feed system fittings resemble pump/liquid fuel apparatus parts under 8413.
