2836.91.00.50 - Other

This HTS category, 2836.91.00.50, encompasses lithium carbonates that do not meet the specific criteria for "U.S.P. grade" established in sibling category 2836.91.00.10. Essentially, it serves as a residual category for lithium carbonates intended for industrial, commercial, or other non-pharmaceutical applications. The key distinction lies in the grade and intended use, with this category covering products that may have different purity standards or are formulated for specific manufacturing processes rather than medicinal purposes.

Lithium carbonate is a white, crystalline inorganic salt with a wide range of industrial uses. These include its application in the manufacturing of ceramics, enamels, and glass, where it acts as a fluxing agent. It is also a critical component in the production of lithium-ion batteries, a rapidly growing sector. Furthermore, lithium carbonate finds use in specialized lubricants and as a raw material in the synthesis of other lithium compounds.

As this is a leaf node, there are no further subcategories within 2836.91.00.50. Classification into this specific code relies on the absence of the criteria that would qualify it for the U.S.P. grade sibling. Importers and exporters should carefully consider the intended application and the material specifications of the lithium carbonate being declared to ensure accurate classification.
