U.S. imports of primary cells & batteries, manganese dioxide (HS 850610) totaled $40.2M in July 2026, traded with 25 countries.
Importers of Primary Cells & Batteries, Manganese Dioxide paid $6.1M in duties in July 2026 — an effective duty rate of 18% on $33.4M in dutiable value, based on actual customs collections rather than the published tariff schedule. Primary Cells & Batteries, Manganese Dioxide imports of $40.2M in July 2026 ran 11% below the year-to-date monthly average of $45.3M.
Last updated: July 2026 dataManganese dioxide primary batteries — the chemistry behind standard alkaline AA, AAA, C, D, and 9V cells as well as button/coin cells (8506100010) — are among the most widely traded consumer goods in Chapter 85. China dominates US import supply, with Indonesia and Vietnam emerging as significant secondary sources as battery manufacturers diversify production. Alkaline cells from China are subject to Section 301 tariffs, a cost factor that has accelerated sourcing shifts to Southeast Asia. The heading's split between button/coin cells and other formats matters for duty calculation and for compliance with state-level battery recycling regulations that vary by cell chemistry and size.

The US schedule separates button and coin cell formats under 8506100010 from all other manganese dioxide primary cells and batteries under 8506100090. The distinction is based on physical form factor: button and coin cells are small, disc-shaped cells typically used in watches, hearing aids, and small electronics. Standard cylindrical or prismatic alkaline cells fall under the NESOI line regardless of capacity.
Primary batteries do not trigger FSIS or APHIS admissibility review. However, importers should be aware that batteries containing certain materials may be subject to EPA regulations under RCRA or state-level extended producer responsibility (EPR) programs. Additionally, batteries marketed as consumer products must comply with CPSC safety standards, and lithium-containing variants (not this heading) face DOT hazmat transport rules. For manganese dioxide alkaline cells specifically, no mandatory federal import permit is required, but compliance with applicable product safety standards should be confirmed.
