Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If for generator or pump drive applications
Non-vehicle propulsion uses place it in the broad 'other spark-ignition engines' category beyond Chapter 87 specifics.
If classified as chain saw powerhead
Identical displacement engines for handheld tools shift to tools chapter when marketed for non-vehicle end use.
If sold as part of unmanned vehicle machinery
Integration into robotic or UAV propulsion (if non-Chapter 87) moves to machines NESOI.
