8701.24.00 - With only electric motor for propulsion

This HTS category, 8701.24.00, specifically classifies road tractors designed for towing semi-trailers that are propelled *solely* by an electric motor. These are vehicles where the primary, and in this case, the only, source of motive power comes from an electric propulsion system. This definition excludes any internal combustion engines, whether diesel, semi-diesel, or spark-ignition, from being part of the propulsion system.

To differentiate this category from its siblings, consider the power source: 8701.21.00 covers tractors with only compression-ignition engines, 8701.22.00 and 8701.23.00 cover tractors with a hybrid electric and internal combustion engine configuration, and 8701.29.00 encompasses all other road tractors not specified in the preceding subheadings. Therefore, 8701.24.00 is exclusively for fully electric road tractors.

Within this classification, a further distinction is made between new and used vehicles. The subheading ".80" is designated for used road tractors that meet the criteria of being solely electrically propelled, allowing for specific accounting and tariff treatment based on their condition and previous use.
