2932.99.90.10 - Glucosamine and its salts and esters 🖩

This HTS category, 2932.99.90.10, specifically classifies glucosamine and its various salts and esters. Glucosamine is an amino sugar that is naturally produced in the human body. Its salts, such as glucosamine hydrochloride and glucosamine sulfate, and its esters are chemical compounds derived from this base structure. These substances are typically found in pharmaceutical preparations, dietary supplements, and occasionally in cosmetic formulations due to their potential health benefits and structural roles in biological systems. The classification hinges on the specific chemical identity of the substance as glucosamine or a direct derivative thereof.

This classification is distinguished from its sibling category, 2932.99.90.90 ("Other"), which encompasses all other heterocyclic compounds containing oxygen hetero-atoms only that do not fall under more specific headings or subheadings within Chapter 29. While both are under the broader "Other" subheadings for heterocyclic compounds, 2932.99.90.10 is a precise designation for glucosamine and its derivatives, whereas the sibling category acts as a residual for all other unclassified substances fitting the broader description of containing oxygen hetero-atoms.

As this is a leaf node in the HTS structure, there are no further subcategories. Therefore, the primary focus for classification under 2932.99.90.10 is to accurately identify the material as glucosamine or one of its direct salts or esters. Importers and exporters must ensure that documentation clearly indicates the presence and identity of glucosamine to justify classification under this specific subheading, as opposed to a more general chemical classification or the residual "Other" category.
