Last updated: August 2026 dataDesigned specifically to deliver the high cranking current needed to start internal combustion engines, these lead-acid batteries are a foundational automotive aftermarket and OEM component. The US schedule breaks the heading by weight at the 12-volt level: batteries at or below 6 kg (8507100030) versus those above 6 kg (8507100060), with a residual line (8507100090) for non-12V configurations. Mexico is the dominant supplier, reflecting deep automotive supply-chain integration under USMCA, while South Korea and Germany supply premium and OEM-specification units. Batteries from Vietnam and Malaysia have grown as manufacturers diversify away from higher-tariff origins.

The 6 kg breakpoint (separating 8507100030 from 8507100060) generally distinguishes smaller motorcycle, powersport, and compact-vehicle batteries from full-size passenger-car and light-truck batteries. Accurate net weight of the battery as imported — excluding packaging — determines the correct line, and misclassification between these two subheadings is a common CBP audit finding.
Batteries originating in Mexico may qualify for preferential treatment under USMCA, provided they meet the applicable rules of origin — typically requiring sufficient regional value content and that the battery be manufactured in North America. Importers should obtain a valid USMCA certification of origin from the Mexican supplier to claim the preference at entry.
