8507.20.80.91 - Other

This HTS category, 8507.20.80.91, classifies "Other" lead-acid storage batteries that do not fall under specific voltage designations within the 8507.20.80 series. It encompasses lead-acid batteries that are not explicitly categorized as 6V, 12V, or 36V. This includes batteries with voltages other than these specific increments, or where voltage is not the primary distinguishing characteristic for classification.

Distinguishing this category from its siblings is crucial. While 8507.20.80.31 covers 6V batteries, 8507.20.80.41 covers 12V batteries, and 8507.20.80.61 covers 36V batteries, this residual "Other" category serves as a catch-all for lead-acid storage batteries that do not fit those defined voltage specifications. This implies that any lead-acid storage battery not explicitly listed in the sibling categories would be directed to this classification.

As a leaf node, this category does not have further subdivisions. Therefore, classification within 8507.20.80.91 relies on a process of elimination, ensuring that the battery in question is indeed a lead-acid storage battery and does not meet the criteria for the more specific voltage-based sibling categories. Classification should be based on the declared voltage or any technical specifications that preclude it from the 6V, 12V, or 36V classifications.
