Parts suitable for use solely or principally with spark-ignition internal combustion piston engine, n.e.s.
2.7%*This subheading has one 8-digit code, so that is the code to use.
This is the catch-all under 8409: it covers what the sibling codes below do not.
Within the parent group of parts for combustion engines, this is where parts mainly or exclusively for spark-ignition piston engines remain after excluding parts for aircraft use and parts for compression-ignition piston engines.
