8507.20 - Other lead-acid storage batteries:

HTS Code 8507.20 encompasses "Other lead-acid storage batteries," serving as a broader category for lead-acid batteries that do not fall under the specific classification for starting piston engines. This means batteries of this type are generally designed for applications other than their primary use in automotive or similar engine starting functions. The distinguishing feature of this category is its residual nature within the lead-acid battery classification, capturing those not explicitly defined as for starting engines.

Compared to sibling categories, 8507.10.00 specifically addresses lead-acid batteries used for starting piston engines. Therefore, 8507.20 covers lead-acid batteries intended for other purposes, such as standby power, deep cycling applications, or specialized industrial uses, where the immediate high-current burst required for engine starting is not the primary design consideration. It's important to note that batteries classified under 8507.20 are still fundamentally lead-acid chemistry.

This category further subdivides into more specific applications. Subcategory 8507.20.40.00 is designated for lead-acid batteries specifically used as the primary power source for electrically powered vehicles falling under certain subheadings of 8703. This highlights a crucial distinction based on the intended end-use application within the electric vehicle sector. The remaining batteries within this group are classified under 8507.20.80 as "Other," representing a diverse range of lead-acid batteries not specifically defined for starting engines or for the particular electric vehicle subheadings mentioned.
