8602 - Other rail locomotives; locomotive tenders:

Heading 8602 encompasses railway locomotives that are not powered by diesel-electric systems, as well as locomotive tenders. This category is part of Section XVII, which deals with vehicles and associated transport equipment. Unlike the broad range of live animals found in Chapter 01, this heading specifically pertains to railway rolling stock and related components, providing a distinct focus on rail transport technology.

The locomotives covered under 8602 are those that do not fall under more specific classifications, such as diesel-electric types. Locomotive tenders, which are unpowered cars that carry fuel and water for steam locomotives, are also included here. This heading is crucial for differentiating between various types of railway motive power and their support equipment, ensuring accurate customs declarations for specialized rail components.

Within heading 8602, two primary subcategories exist: 8602.10.00.00 for diesel-electric locomotives and 8602.90.00.00 for all other types. The distinction is based on the primary propulsion system. Therefore, when classifying items under 8602, the key determinant is whether the locomotive is diesel-electric or employs a different method of power, such as steam or purely electric traction (though purely electric locomotives would typically be classified elsewhere based on their power source if not specifically a hybrid system that fits 8602.10).
