8506.10.00.90 - Other

This HTS category, 8506.10.00.90, covers "Other" primary cells and primary batteries utilizing manganese dioxide as their primary active material. This encompasses a wide range of manganese dioxide battery types not specifically enumerated in other subheadings. It is important to note that the primary function of these items is to convert chemical energy into electrical energy for immediate use without recharging.

This classification is distinguished from its sibling, 8506.10.00.10, which specifically covers button and coin cell batteries. While both utilize manganese dioxide, the key differentiator here is the exclusion of the specifically defined button and coin cell configurations. Therefore, any manganese dioxide primary battery that does not fit the physical dimensions and form factor of a button or coin cell would fall under this residual "Other" category.

As this is a leaf node within the HTS classification system, there are no further subcategories. Classification within 8506.10.00.90 is determined by the absence of specific descriptive criteria met by other enumerated categories within the manganese dioxide primary battery heading, provided the battery is indeed a primary cell or battery and utilizes manganese dioxide.
