U.S. imports of parts of electric accumulators (SITC 77819) totaled $385.4M in April 2026, traded with 46 countries.
Importers of Parts of Electric Accumulators paid $25.8M in duties in April 2026 — an effective duty rate of 15% on $174.8M in dutiable value, based on actual customs collections rather than the published tariff schedule. Parts of Electric Accumulators imports of $385.4M in April 2026 ran 54% above the year-to-date monthly average of $251.0M.
Last updated: April 2026 dataElectric accumulator parts — including plates, separators, electrolyte containers, and terminal hardware for lead-acid, lithium-ion, nickel-metal hydride, and other rechargeable battery technologies — are a strategically sensitive import category given their role in EV, grid storage, and consumer electronics supply chains. Section 301 tariffs have affected Chinese-origin accumulator components, and the broader policy environment around battery supply chain localization (including IRA-related considerations) makes origin and content documentation increasingly important. Distinguishing parts from complete cells or modules is a recurring classification challenge at the subheading level.
AI-written summary of the official U.S. Census Bureau trade figures on this page — verify before relying on it.
A complete electrochemical cell — even unassembled — is generally classified as a cell or battery rather than a part. True 'parts' are components that do not independently perform an electrochemical function, such as separators, terminal connectors, or housing elements. When a component could be classified either way, CBP binding ruling requests can provide certainty before importation.
Beyond duty classification, accumulator parts entering EV and energy storage supply chains may be subject to domestic content tracking under US incentive programs. Importers and manufacturers increasingly need detailed material and origin documentation at the component level to support downstream compliance certifications, making thorough record-keeping at entry a practical necessity.
