8504.90.96.10 - For transformers

This HTS category, 8504.90.96.10, specifically classifies ferrite parts for electrical transformers. Ferrites are magnetic ceramic materials primarily composed of iron oxides mixed with other metallic elements. Within the context of transformers, these ferrite components are crucial for their magnetic core, enabling efficient energy transfer. This classification is reserved for such ferrite components when they are solely intended for use as parts of transformers, as opposed to other electrical machinery.

This subcategory is distinguished from its sibling, 8504.90.96.30 "Other," which would encompass non-ferrite parts for transformers or ferrite parts for other electrical apparatus covered by heading 8504, such as static converters or inductors. The defining characteristic here is the material (ferrite) and the intended application (transformers).

As this is a leaf node, there are no further subcategories. Therefore, classification under this code hinges on confirming the item is indeed a ferrite component and that its sole designated use is as a part of a transformer. Examples of such parts could include ferrite cores, toroids, or bobbins that are specifically designed to form the magnetic structure of a transformer.
