U.S. imports of silver oxide primary cells and batteries (HS 850640) totaled $12.5M in June 2026, traded with 4 countries.
Importers of Silver Oxide Primary Cells and Batteries paid $864K in duties in June 2026 — an effective duty rate of 12% on $7.1M in dutiable value, based on actual customs collections rather than the published tariff schedule. Silver Oxide Primary Cells and Batteries imports of $12.5M in June 2026 ran 72% above the year-to-date monthly average of $7.2M.
Last updated: June 2026 dataSilver oxide chemistry delivers a stable, flat discharge voltage that makes these non-rechargeable cells the preferred power source for precision instruments, hearing aids, and high-end watches. The US tariff schedule subdivides the heading by volume: batteries at or below 300 cm³ (8506401010 for button/coin cells; 8506401090 for other small formats) and those exceeding 300 cm³ (8506405000). Japan and Switzerland dominate US supply, reflecting the close integration of these cells with the watchmaking and precision-instrument industries concentrated in those countries. Importers should note that button-cell batteries face additional federal safety-labeling requirements under the Reese's Law consumer-protection framework.
AI-written summary of the official U.S. Census Bureau trade figures on this page — verify before relying on it.
The split is based on physical volume: batteries at or below 300 cm³ fall under 8506401010 (button/coin cells) or 8506401090 (other small formats), while those exceeding 300 cm³ are classified under 8506405000. Correct measurement of the assembled battery volume is essential to avoid misclassification.
Yes. Reese's Law (enacted 2022) imposes child-resistant packaging and warning-label requirements on consumer products containing button and coin cells, including silver oxide types. Importers must ensure products and their packaging comply before entry, as CBP and the CPSC may detain non-compliant shipments.
