8511.40.00.00 - Starter motors and dual purpose starter-generators

HTS code 8511.40.00.00 specifically classifies starter motors and dual-purpose starter-generators. These devices are designed to initiate the operation of internal combustion engines by providing the initial rotational force required to start them. Starter-generators, as the name suggests, can perform both the starting function and, when the engine is running, generate electrical power, often serving as an alternator or dynamo.

This classification is distinct from its siblings within heading 8511. For instance, while spark plugs (8511.10.00.00) are crucial for ignition in gasoline engines, they are not motor-driven starting devices. Similarly, ignition magnetos and distributors (8511.20.00.00 and 8511.30.00) are solely responsible for generating or distributing the ignition spark, not for physically turning the engine over. Other generators (8511.50.00.00) in this heading typically refer to those that produce electrical power during engine operation but do not have a primary starting function.

As a leaf node within the HTS, 8511.40.00.00 does not have further subdivisions. Therefore, classification under this code relies on accurately identifying the primary function and design of the electrical component as either a dedicated starter motor or a combined starter-generator for internal combustion engines. This ensures accurate duty assessment and trade statistics for these essential engine components.
