This product may fall under a more specific subheading:
Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If it were strontium carbonate for pyrotechnics
Strontium carbonates have dedicated subheading 2836.92.00, separating from generic 'other' lithium carbonates.
If mined as natural fluxing limestone containing lithium
Natural calcium fluoride or fluorspar with lithium falls under Chapter 25 as mineral products, not refined chemicals.
If sold in bulk as unspecified chemical flux mixture
Non-chemically defined preparations or mixtures default to Chapter 38 headings.

Import Tips & Compliance
• Label packages with exact assay percentage and CAS number (554-13-2) for verification; check for REACH-like compliance if transshipping from EU
• Avoid common pitfall of declaring as 'lithium salts n.e.s.' which could trigger 2847
Related Products under HTS 2836.91.00
Lithium Carbonate Powder
Pure lithium carbonate (Li2CO3) in fine powder form, used primarily as a raw material in the production of lithium-ion battery cathodes and glass ceramics. It falls under HTS 2836.91.00 as a chemically defined carbonate of lithium, specifically classified as 'lithium carbonates' per Chapter 28 notes excluding certain stabilized or complex forms. This anhydrous, high-purity compound meets the criteria for inorganic carbonates in this heading.
Battery-Grade Lithium Carbonate
High-purity lithium carbonate optimized for lithium-ion battery cathode synthesis, with low impurity levels (<20 ppm Na). Classified under HTS 2836.91.00 as it is a simple inorganic lithium carbonate, distinct from complex salts or stabilized forms per Chapter 28 Note 2(e). Used in NMC and LFP cathode materials.
Pharmaceutical Lithium Carbonate USP
Ultra-pure Li2CO3 meeting USP standards for use in psychiatric medications like bipolar treatment drugs. Falls under HTS 2836.91.00 as a simple inorganic carbonate, prior to formulation into finished pharmaceuticals excluded by Section VI notes.
Anhydrous Lithium Carbonate Crystals
Crystalline form of pure Li2CO3 without hydration, used in specialty ceramics and enamel frits. Classified in HTS 2836.91.00 as it matches the definition of lithium carbonates, excluding glass frit powders under Chapter 32 per chapter exclusions.
Lithium Carbonate Monohydrate
Li2CO3·H2O form commonly precipitated from brine processing, used in cement and polymer additives. HTS 2836.91.00 applies as hydrated carbonates remain classified as lithium carbonates unless forming complex organo-inorganics.
