8702.10 - With only compression-ignition internal combustion piston engine (diesel or semi-diesel):

This HTS category, 8702.10, specifically covers motor vehicles designed for the transport of ten or more persons, including the driver, that are powered *solely* by a compression-ignition internal combustion piston engine, commonly known as diesel or semi-diesel engines. These vehicles are distinct from other categories within 8702 based on their primary propulsion system.

The key differentiator for 8702.10 is the exclusive use of a diesel or semi-diesel engine for propulsion. This excludes vehicles that utilize a combination of diesel and electric motors (8702.20), spark-ignition and electric motors (8702.30), or solely electric motors (8702.40) for their primary motive force. Vehicles not fitting these specific propulsion criteria, and not otherwise categorized, would fall under the "Other" category (8702.90).

Within 8702.10, further classification is based on the passenger capacity. Subcategories distinguish between vehicles designed for transporting a larger group, specifically 16 or more persons including the driver (8702.10.31.00), and all other vehicles within this diesel-powered category that accommodate ten to fifteen persons, including the driver (8702.10.61.00). This subdivision allows for more granular tariff application based on the intended scale of passenger transport.
