Last updated: July 2026 dataBeyond automotive starters, lead-acid storage batteries serve stationary backup power, renewable-energy storage, industrial forklifts, and — increasingly — mild-hybrid vehicle systems. The US tariff schedule is unusually granular here, with dedicated lines for 6-volt (8507208031), 12-volt (8507208041), and 36-volt (8507208061) configurations, a line for batteries serving as the primary power source for electric vehicles of headings 8703.40–8703.80 (8507204000), and a special line (8507208010) for batteries covered by subheading 9903.45.25. Mexico and Vietnam lead US supply, with China also a major source subject to Section 301 tariffs. Importers must carefully match voltage and end-use to the correct 10-digit line, as the EV-power-source line carries distinct duty treatment.

8507204000 applies to lead-acid storage batteries used as the primary source of electrical power for electric vehicles classified under HTS headings 8703.40 through 8703.80. The battery must be purpose-built and documented for that vehicle application; general-purpose deep-cycle batteries sold separately for aftermarket use typically fall under the standard voltage-based lines.
Subheading 9903.45.25 is a Section 301 tariff provision applicable to certain goods of Chinese origin. Lead-acid storage batteries from China that fall within its scope are entered on line 8507208010 to capture the additional duty. Importers sourcing from China should verify whether their specific product and origin qualify under this provision, as the scope and rates are subject to ongoing USTR review.
