8506.60.00.90 - Other

This HTS category, 8506.60.00.90, specifically covers "Other" air-zinc primary cells and batteries. It is designed to capture air-zinc powered energy storage devices that do not fit into more specific subcategories within the broader air-zinc classification. These are typically single-use electrochemical cells where oxygen from the surrounding air acts as the active cathode material. Common applications for such batteries include hearing aids and certain portable electronic devices.

It is crucial to distinguish this category from its sibling, HTS 8506.60.00.10, which exclusively classifies button and coin cell air-zinc batteries. While both fall under the air-zinc primary battery umbrella, this "Other" category is for air-zinc cells that are not in the button or coin form factor. This distinction is based on physical dimensions and shape, allowing for more precise classification of a wider range of air-zinc battery types.

As this node is a leaf node, there are no further subcategories. Therefore, the classification hinges on whether a particular air-zinc primary cell or battery falls outside the scope of button and coin cell types. If an air-zinc primary cell or battery does not meet the definition of a button or coin cell, it will be classified under this "Other" category.
