8506.10.00.10 - Button and coin cell batteries

This HTS category specifically covers button and coin cell batteries that utilize manganese dioxide as the primary active material. These compact power sources are commonly found in small electronic devices, such as watches, calculators, key fobs, and medical devices. The defining characteristic for classification under 8506.10.00.10 is the chemical composition, specifically the presence of manganese dioxide in the primary cell or battery construction.

This classification is distinguished from its sibling, 8506.10.00.90, which encompasses all other primary cells and batteries utilizing manganese dioxide that do not fit the specific definition of button and coin cells. Therefore, if a manganese dioxide battery is not in a button or coin shape, it would fall under the "Other" category. This distinction is crucial for accurate tariff application, as it narrows the scope to a very specific form factor and common application.

As this is a leaf node within the HTS, there are no further subcategories for this specific item. Classification at this level is definitive based on the product being a button or coin cell battery made with manganese dioxide. When encountering such an item, a trade professional should confirm its form factor and primary active material to ensure correct classification under 8506.10.00.10.
