8506.60.00.10 - Button and coin cell batteries

This HTS subheading, 8506.60.00.10, specifically classifies button and coin cell batteries. These are typically small, flat, cylindrical primary cells designed for low-drain, long-life applications. Examples include batteries used in watches, calculators, key fobs, small electronic toys, and medical devices like glucose meters. The defining characteristic is their compact size and shape, resembling a button or a coin.

Within the broader category of "Air-zinc" primary cells and batteries, this subheading is distinguished by its focus on the physical form factor rather than the specific chemistry or technology. While other air-zinc batteries might exist, this code is reserved for those that meet the "button" or "coin" cell criteria.

As this is a leaf node within the HTS structure, there are no further subcategories for this specific classification. Therefore, the classification hinges on identifying whether the air-zinc primary battery conforms to the physical dimensions and general shape of a button or coin cell.
