U.S. exports of Parts of Primary Cells and Primary Batteries (SITC 77817) totaled $2.8M in August 2026.
Importers of Parts of Primary Cells and Primary Batteries paid $187K in duties in August 2026, an average duty rate of 9.74% — duty actually collected as a share of the imports that cleared customs, not the published tariff schedule. Parts of Primary Cells and Primary Batteries imports of $1.9M in August 2026 ran 46% above the year-to-date monthly average of $1.3M.
Last updated: August 2026 dataComponents destined for primary (non-rechargeable) cells and batteries — such as electrode materials, separators, and casings — occupy a distinct classification from finished battery assemblies and from accumulator parts. Section 301 tariffs have applied broadly to Chinese-origin electrical components in this space, making supplier origin a critical cost variable for importers. These parts feed into consumer electronics, medical devices, and industrial instrumentation supply chains where cell chemistry and dimensional tolerances drive sourcing decisions.

SITC 77817 covers parts specific to primary (single-use) cells and batteries, while parts of electric accumulators (rechargeable batteries) fall under a separate heading. The key classification question is whether the component is designed exclusively for a primary cell or is interchangeable with accumulator use — shared-use parts may require a different classification determination.
Yes. Many electrical component parts, including those used in primary cells, have been subject to Section 301 tariffs when originating from China. Importers should verify the applicable HTS 10-digit classification and confirm current Section 301 list coverage with a licensed customs broker, as product-specific exclusions and modifications have changed over time.
