8702.30 - With both spark-ignition internal combustion piston engine and electric motor as motors for propulsion:

This category, HTS Code 8702.30, specifically covers motor vehicles designed for the transport of ten or more persons, including the driver, that utilize a hybrid propulsion system. The defining characteristic is the presence of both a spark-ignition internal combustion piston engine and an electric motor, both of which serve as motors for propulsion. This dual-engine setup distinguishes these vehicles from those powered solely by a compression-ignition engine (8702.10), a combination of a compression-ignition engine and an electric motor (8702.20), or solely by an electric motor (8702.40).

Further subdivision within 8702.30 is based on the vehicle's passenger capacity. Subcategory 8702.30.31.00 applies to vehicles designed to transport 16 or more persons, including the driver, accommodating larger group or public transportation needs. Conversely, subcategory 8702.30.61.00 encompasses "Other" vehicles within this hybrid propulsion framework, which would typically include those designed for the transport of 10 to 15 persons, including the driver, or other specialized vehicles meeting the hybrid propulsion criteria but not fitting the larger capacity designation.
