8511.30.00.80 - Ignition coils

This HTS category specifically covers ignition coils, which are essential components of the ignition system in internal combustion engines. Ignition coils are transformer devices that convert the low voltage from a vehicle's battery into the high voltage necessary to create an electrical spark across the spark plug, igniting the fuel-air mixture. They are designed for use in both spark-ignition and compression-ignition engines.

At this level, this category is distinguished from its sibling, HTS 8511.30.00.40, which covers distributors. While both are part of the ignition system, distributors are responsible for directing the high-voltage current from the ignition coil to the correct spark plug at the appropriate time, whereas ignition coils are solely responsible for generating that high-voltage current.

As this is a leaf node within the HTS structure, there are no further subcategories. Therefore, the classification of goods under 8511.30.00.80 relies entirely on their definitive characteristic as ignition coils, fulfilling the function described within the broader heading for electrical ignition or starting equipment for internal combustion engines.
