Many battery types imported from China are subject to Section 301 tariffs. The specific tariff treatment depends on the HTS classification of the battery — primary versus secondary, chemistry type, and intended application all affect which tariff lines apply, so consulting a licensed customs broker is advisable.

Primary batteries are non-rechargeable (e.g., alkaline or lithium disposable cells), while secondary batteries are rechargeable (e.g., lithium-ion, nickel-metal hydride). This distinction drives separate HTS classifications under Chapter 85 and can affect applicable duty rates, Section 301 exposure, and any applicable trade remedy orders.
