8507.30.80.10 - Sealed

This HTS category, 8507.30.80.10, specifically covers "Sealed" nickel-cadmium storage batteries. This designation applies to batteries that are hermetically sealed, preventing the escape of electrolyte and gases during normal operation. These batteries are commonly found in portable electronics, power tools, and emergency lighting systems where reliable and contained power sources are essential. The "sealed" characteristic is a key differentiator, indicating a design feature that enhances safety and portability compared to vented types.

While the parent category addresses nickel-cadmium storage batteries broadly, and the sibling category 8507.30.80.90 encompasses "Other" nickel-cadmium batteries, this subcategory focuses exclusively on those that are sealed. The distinction lies in the construction and containment of the battery. Vented batteries, for instance, may allow for gas or electrolyte release under certain conditions, whereas sealed versions are designed to prevent this. Therefore, classification hinges on whether the battery's enclosure is designed to be permanently sealed during its operational life.

As this is a leaf node in the HTS structure, there are no further subdivisions under this specific code. Classification decisions at this level should therefore rely on a thorough examination of the battery's physical characteristics to confirm its sealed nature, differentiating it from any potentially vented or otherwise non-sealed nickel-cadmium storage batteries that would fall under the "Other" sibling category.
