U.S. exports of lithium oxide and hydroxide (HS 282520) totaled $10.1M in July 2026.
Importers of Lithium Oxide and Hydroxide paid $43K in duties in July 2026 — an effective duty rate of 14% on $299K in dutiable value, based on actual customs collections rather than the published tariff schedule.
Last updated: July 2026 dataLithium hydroxide has become a strategically critical battery-grade chemical, serving as a primary cathode precursor for high-nickel lithium-ion cells used in electric vehicles and grid storage. Chile and Australia are the dominant US suppliers, reflecting their positions as the world's leading lithium brine and hard-rock producers, respectively. China also appears among the top sources, which is significant given that imports from China may be subject to Section 301 tariffs. The entire heading is captured under a single tariff line (2825200000), making grade and purity specifications — battery-grade versus technical-grade — a key commercial distinction even though the HTS does not subdivide them.

No — tariff line 2825200000 covers all lithium oxide and hydroxide regardless of purity grade. However, the commercial distinction between battery-grade (high-purity, low-impurity) and technical-grade product is critical for buyers in the EV supply chain, and purity specifications should be clearly stated in purchase contracts and certificates of analysis even though they do not affect the tariff classification.
Yes. Imports of lithium hydroxide from China under this heading are subject to Section 301 tariffs. Importers sourcing from China should confirm the applicable Section 301 list and any exclusion orders in effect at the time of entry, as these can change. Sourcing from Chile or Australia avoids Section 301 exposure.
