8506.50.00 - Lithium

This HTS category, 8506.50.00, specifically covers primary cells and primary batteries where the active cathode material is lithium. These power sources utilize lithium in a non-rechargeable configuration, making them distinct from secondary (rechargeable) batteries. Their high energy density and long shelf life are characteristic features of lithium-based primary batteries.

Distinguishing this category from its siblings, other entries under 8506 cover primary cells and batteries with different active cathode materials, such as manganese dioxide (8506.10.00), mercuric oxide (8506.30), silver oxide (8506.40), and air-zinc (8506.60.00). While all fall under the umbrella of primary batteries, the specific chemical composition of the cathode is the key differentiator for classification.

Within the lithium primary battery category, two subcategories exist: 8506.50.00.10 for button and coin cell batteries, and 8506.50.00.90 for all other types of lithium primary cells and batteries. This subdivision allows for more granular classification based on the physical form factor of the lithium battery, catering to the diverse applications of these compact power sources.
