U.S. imports of lithium primary cells and batteries (HS 850650) totaled $31.8M in April 2026, traded with 39 countries.
Last updated: April 2026 dataNon-rechargeable lithium primary batteries — covering button/coin cells (8506500010) and all other formats (8506500090) — are widely used in medical devices, military equipment, remote sensors, and consumer electronics where long shelf life and high energy density are critical. Imports from China are subject to Section 301 tariffs, making origin verification and supply-chain diversification a priority for US buyers; Singapore and Japan are significant alternative sources. Shipments containing lithium cells are also regulated as hazardous materials under DOT/IATA rules, requiring proper classification, packaging, and documentation at the time of import.
AI-written summary of the official U.S. Census Bureau trade figures on this page — verify before relying on it.
Lithium primary batteries are classified as dangerous goods under DOT 49 CFR and IATA regulations. Importers must ensure shipments are accompanied by proper UN specification markings (UN 3090 for lithium metal cells), state-of-charge certifications, and compliant packaging. Air shipments face particularly strict quantity and packaging limits.
8506500010 covers lithium primary batteries in button or coin form factor — small, disc-shaped cells typically used in watches, hearing aids, and key fobs. 8506500090 captures all other lithium primary battery formats, such as cylindrical or prismatic cells used in cameras, medical devices, and industrial sensors. Physical form factor, not chemistry, drives the split.
