8538.90.81.20 - Of automatic circuit breakers 🖩

HTS Code 8538.90.81.20 classifies specific parts that are designed for use with automatic circuit breakers. These parts are integral to the functioning and protection mechanisms of these electrical safety devices, ensuring their proper operation in various electrical systems. This encompasses a wide range of components that, while not complete circuit breakers themselves, are essential for their assembly, maintenance, or enhancement.

This specific subcategory, "Of automatic circuit breakers," is a further refinement within the broader "Other" categories at this level of the HTS. Unlike other "Other" subcategories which might cover parts for a wider range of apparatus under headings 8535, 8536, or 8537, this classification is exclusively for components dedicated to automatic circuit breakers. This distinction is crucial for accurate import and export declarations, as it targets a very specific type of electrical component with unique functional requirements and applications.

As this is a leaf node in the HTS, there are no further subcategories. Therefore, classification at 8538.90.81.20 is the final designation for these specialized parts. Examples of goods that would fall under this classification include internal operating mechanisms, tripping units, or specific housing components designed solely for automatic circuit breakers, provided they are not separately classified as a finished article. The key criterion is that the part's design and intended use are exclusively for automatic circuit breakers.
