U.S. exports of primary battery and cell parts (HS 850690) totaled $1.9M in July 2026.
Importers of Primary Battery and Cell Parts paid $155K in duties in July 2026 — an effective duty rate of 15% on $1.0M in dutiable value, based on actual customs collections rather than the published tariff schedule. Primary Battery and Cell Parts imports of $1.4M in July 2026 ran 16% above the year-to-date monthly average of $1.2M.
Last updated: July 2026 dataParts of primary cells and batteries — including electrode assemblies, separators, casings, and terminals — are consolidated into a single 10-digit line (8506900000) under this heading. Mexico is the leading US supplier, consistent with its role as a major assembly hub for battery components destined for North American manufacturers under integrated supply chains. China and Germany are also significant sources. Correct classification of parts versus complete cells is a recurring audit issue; CBP generally requires that parts be identifiable as solely or principally used in primary cells to remain in heading 8506 rather than being classified by constituent material.

CBP applies the 'parts' classification principle: the article must be identifiable as solely or principally used in primary cells or batteries, and it must not be more specifically provided for elsewhere in the tariff schedule. Generic materials (e.g., plain steel sheet) that could serve many purposes are typically classified by material; purpose-built electrode substrates or molded battery casings are more likely to qualify as parts under 8506.90.
Yes. Parts of primary cells and batteries classified under 8506.90 and originating in China are subject to Section 301 tariffs. Importers sourcing from Mexico may benefit from USMCA treatment if the parts meet applicable rules of origin, which is a key reason Mexico has become a prominent supplier for North American battery manufacturers.
