8407.31.00.80 - Other

This HTS category, 8407.31.00.80, encompasses "Other" spark-ignition reciprocating or rotary internal combustion piston engines used for the propulsion of vehicles of Chapter 87, specifically those with a cylinder capacity not exceeding 50 cubic centimeters (cc). This classification serves as a residual category for engines meeting the broad criteria of ignition type, engine type, vehicle propulsion application, and cylinder displacement, but not fitting into more specific sub-classifications.

This category is distinguished from its sibling, 8407.31.00.40, by the absence of a specific power output threshold. While the sibling category is defined by engines of less than 746 Watts, this category captures any remaining engines within the 50 cc displacement limit that do not meet that power criterion. The primary differentiator remains the cylinder capacity, with this node applying to any engine within that limit that doesn't fall under a more specific power-based description.

As this is a leaf node within the HTS structure, there are no further subcategories. Therefore, classification into 8407.31.00.80 is final if an engine meets the conditions of being a spark-ignition reciprocating or rotary internal combustion piston engine, designed for vehicle propulsion (Chapter 87), and having a cylinder capacity not exceeding 50 cc, and does not qualify for any more granular classification based on power output or other specific criteria that might exist at higher levels of detail. Examples would include small displacement engines for scooters, mopeds, or similar light vehicles that do not fit a 746W power constraint.
