2922.41.00.90 - Other

This HTS category, 2922.41.00.90, covers lysine and its esters and salts that do not meet the specific purity or quality standards of recognized compendia like the Food Chemical Codex, Codex Alimentarius, or the United States Pharmacopeia. In essence, it encompasses lysine-based compounds that are not intended for pharmaceutical or food-grade applications where stringent quality assurances are mandated. Examples could include lysine derivatives used in industrial processes, animal feed supplements not meeting the highest food-grade standards, or research-grade lysine not intended for human consumption.

Distinguishing this category from its sibling, 2922.41.00.10, is crucial for accurate classification. While both deal with lysine and its salts/esters, the key differentiator lies in the quality and intended use. Category 2922.41.00.10 specifically designates those products meeting the rigorous specifications outlined in the Food Chemical Codex, Codex Alimentarius, or the United States Pharmacopeia, implying a higher purity and suitability for direct human consumption or pharmaceutical formulations. Therefore, this category serves as a residual classification for lysine-based compounds that fall outside these elite specifications.

As this is a leaf node, there are no further subcategories under 2922.41.00.90. Classification under this code is definitive once it has been established that the product is a lysine, its ester, or its salt, and it does not qualify for the more specific category based on compendial standards. The classification hinges on the absence of meeting specific purity and quality benchmarks that would place it into the sibling category.
