Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If long but without external threads
Internal-only threading (no external) would be 'other' brass fittings.
If ductile iron long nipple
Cast iron long-radius nipples use ferrous pipe fittings classification.
If machined from cast brass chain rather than extruded
Powder metallurgy or cast articles of copper may use the chain/powder heading.

Import Tips & Compliance
• Measure and declare exact length; very long nipples (>12 inches) may classify as fabricated tubes
• Include burst pressure testing for gas service applications to prove fitting integrity
• Avoid describing as 'extensions' which could misdirect to plain tube headings
