Last updated: April 2026 dataRechargeable storage batteries — spanning lead-acid, nickel-metal hydride, lithium-ion, and emerging solid-state chemistries — are a focal point of US trade policy given their role in electric vehicles, grid storage, and consumer electronics. Lithium-ion cells and battery packs sourced from China are subject to Section 301 tariffs, and the heading has attracted antidumping and countervailing duty investigations targeting specific chemistries and form factors. The EV battery supply chain has also drawn scrutiny under the Inflation Reduction Act's domestic-content and foreign-entity-of-concern provisions, which interact with — but are separate from — customs classification and duty obligations.

The IRA's clean-vehicle tax credit rules impose domestic-content and supply-chain requirements that are administered separately from CBP customs duties. A battery pack may clear customs and pay applicable Section 301 tariffs while still failing IRA eligibility tests — or vice versa. Importers and vehicle manufacturers should treat IRA compliance as a parallel track managed with tax counsel, not a substitute for customs classification.
Large-format lithium-ion cells and modules are regulated as Class 9 dangerous goods under IATA and IMDG, with state-of-charge limits, UN-specification packaging, and testing requirements under UN 38.3. Ocean carriers and airlines may impose additional restrictions. These transport requirements are separate from customs entry obligations and must be addressed in the shipping documentation before cargo is tendered.
