2836.91.00.10 - U.S.P. grade

This HTS classification, 2836.91.00.10, specifically covers lithium carbonates that meet the standards for United States Pharmacopeia (U.S.P. grade). This designation signifies that the lithium carbonate has been manufactured to meet stringent purity and quality requirements for pharmaceutical use, ensuring its suitability for medicinal applications and as an ingredient in regulated products.

The distinction between this subcategory and its sibling, 2836.91.00.50 "Other," lies in the specific quality standard. While both classify lithium carbonates, 2836.91.00.10 is exclusively for material tested and certified to U.S.P. grade. The "Other" category would encompass lithium carbonates that do not meet this specific pharmaceutical standard, such as industrial-grade or technical-grade lithium carbonates used in manufacturing, battery production, or other non-pharmaceutical applications.

As a leaf node in the HTS database, this category does not have further subcategories. Therefore, the focus for classification under 2836.91.00.10 is solely on verifying that the imported or exported lithium carbonate is indeed U.S.P. grade, meaning it has undergone testing and meets the official pharmacopeial standards for identity, strength, quality, and purity.
