U.S. imports of lead-acid starter batteries for piston engines (HS 850710) totaled $189.9M in April 2026, traded with 38 countries.
Importers of Lead-Acid Starter Batteries for Piston Engines paid $15.8M in duties in April 2026 — an effective duty rate of 16% on $99.1M in dutiable value, based on actual customs collections rather than the published tariff schedule.
Last updated: April 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.
AI-written summary of the official U.S. Census Bureau trade figures on this page — verify before relying on it.
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.
