Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If flexible with attached short hose section
Assembled hose-fittings classify under flexible tubes, not separate fittings.
If precision-engineered for valves/appliances
Appliance valves/taps have specific Chapter 84 headings over general fittings.
If for automotive or machinery end-use
Vehicle/machine-specific fittings shift to parts of those articles.
