8506.40.10.90 - Other

This HTS subcategory, 8506.40.10.90, encompasses primary silver oxide batteries whose external volume exceeds 300 cubic centimeters (cm³). These are typically larger, more robust power sources designed for applications requiring sustained power output or extended operational life beyond what smaller button or coin cells can provide. Examples might include specialized industrial equipment, medical devices, or military applications where larger battery dimensions are necessary.

The key differentiator for this category lies in its volume specification. It is distinct from its sibling category, 8506.40.10.10, which specifically covers button and coin cell batteries. While both fall under primary silver oxide batteries having an external volume not exceeding 300 cm³, the "Other" designation here signifies larger batteries that do not conform to the compact, disc-like form factor of button and coin cells. Classification relies on the physical dimensions of the battery unit.

As this is a leaf node in the HTS structure, there are no further subcategories. Therefore, the classification hinges solely on identifying primary silver oxide batteries that meet the volumetric requirement of not exceeding 300 cm³ and are not specifically of the button or coin cell variety. Importers and exporters should verify the external volume and the form factor of the silver oxide battery to ensure accurate classification.
