8506.80.00.90 - Other

This category, HTS Code 8506.80.00.90, encompasses primary cells and primary batteries that are not specifically classified under other headings within Chapter 85. It serves as a residual category for these power sources. Examples of items that would fall here include non-rechargeable batteries not of the button or coin cell variety. The primary focus is on the electrochemical device designed to convert stored chemical energy directly into electrical energy and is not intended for recharging.

This "Other" category is distinguished from its sibling, 8506.80.00.10, which specifically covers button and coin cell batteries. Those are typically small, flat, and circular, often used in watches, calculators, and small electronic devices. Therefore, any primary cell or primary battery that does not fit the description of a button or coin cell, and is not otherwise enumerated, will find its classification here.

As this is a leaf node, there are no further subcategories within 8506.80.00.90. Classification within this category is determined by the exclusion of goods from more specific headings within the primary cell and battery section. It is crucial to examine the physical form, intended application, and electrochemical composition to ensure correct classification under this residual heading, thereby avoiding misclassification with other types of batteries or electrochemical devices.
