Products classified under Tariff item 2825.20.00.00
Anhydrous Lithium Hydroxide
Anhydrous lithium hydroxide (LiOH) is a white, hygroscopic powder used in grease manufacturing, CO2 scrubbing systems, and as a flux in ceramics. It is a separate chemically defined inorganic compound of lithium, falling squarely under tariff item 2825.20.00 as lithium hydroxide.
2825.20.00Battery-Grade Lithium Hydroxide
Battery-grade lithium hydroxide is a high-purity (>99.5%) form of LiOH specifically optimized for producing nickel-manganese-cobalt (NMC) cathodes in electric vehicle batteries. As a chemically defined lithium hydroxide compound, it is classified under tariff item 2825.20.00 regardless of its specialized application.
2825.20.00High-Purity Lithium Oxide
High-purity lithium oxide (Li₂O) is a white powder used in specialty glass for optical fibers and as a dopant in ferroelectric ceramics. As a separate chemically defined compound of lithium, it is classified under tariff item 2825.20.00 as lithium oxide.
2825.20.00Lithium Hydroxide for Grease Production
Lithium hydroxide flakes for grease production are a form of LiOH designed for high-temperature lithium complex grease manufacturing. Despite the specialized application, the product remains a chemically defined lithium hydroxide and is classified under tariff item 2825.20.00.
2825.20.00Lithium Hydroxide Monohydrate
Lithium hydroxide monohydrate (LiOH·H₂O) is a crystalline powder used in lithium-ion battery cathodes and as a precursor for lithium salts. As a hydrate of lithium hydroxide, it is classified under tariff item 2825.20.00 as lithium hydroxide.
2825.20.00Lithium Hydroxide Solution 10%
A 10% aqueous solution of lithium hydroxide is used for pH control in chemical processing and leather tanning. Under Chapter 28 Note 1(b), solutions of separate chemically defined compounds in water are classified in the same heading as the compound, so this falls under tariff item 2825.20.00.
2825.20.00Lithium Oxide Powder
Lithium oxide (Li₂O) powder is an inorganic base used in glass manufacturing to lower melting points and in ceramics for fluxing properties. As a separate chemically defined compound, it is classified under tariff item 2825.20.00 as lithium oxide.
2825.20.00Micronized Lithium Hydroxide
Micronized lithium hydroxide with a particle size below 10 μm is used for spray drying in battery precursor manufacturing. The particle size does not alter the chemical definition of the product, so it remains classified under tariff item 2825.20.00 as lithium hydroxide.
2825.20.00Technical-Grade Lithium Hydroxide
Technical-grade lithium hydroxide (92-98% purity) is used for pH adjustment in wastewater treatment and as a raw material in specialty chemicals. Even at lower purity, it remains a separate chemically defined compound of lithium hydroxide and is classified under tariff item 2825.20.00.
