This product may fall under a more specific subheading:

Alternative Classifications

This product could be classified differently depending on its characteristics or intended use.

2836.20.00Higher: 36.2% vs 28.7%

If it were a calcium carbonate instead, common glass additive

Different metal base (calcium vs. lithium) changes classification within the same 'other carbonates' subheading.

3811.90.00Higher: 41.5% vs 28.7%

If post-reaction as catalyst residue in battery production

Spent or reacted carbonates used as catalysts fall under Chapter 38 for catalyst preparations.

2846.90.80Lower: 3.7% vs 28.7%

If doped with rare earth compounds for specialized salts

Complex or doped salts with radioactive/rare earth elements move to heading 2846 per Chapter notes.

Import Tips & Compliance

Provide spectrographic analysis confirming <10 ppm metallic impurities to avoid reclassification; include end-use statements for battery manufacturing to qualify for potential exclusions

Beware of Section 301 tariffs on Chinese-origin material

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.

Technical Grade Lithium Carbonate

Industrial-grade Li2CO3 used in glass manufacturing and as a flux, with purity around 99%. It qualifies for HTS 2836.91.00 as a chemically defined lithium carbonate, not covered under exclusions for organo-inorganic compounds or Chapter 31 derivatives in the chapter notes.

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.
