2936.29.16.10 - Pharmaceutical grade

This HTS category, 2936.29.16.10, specifically covers pharmaceutical grade niacin. Niacin, also known as nicotinic acid, is a B vitamin (B3) that plays a crucial role in metabolism. The designation "pharmaceutical grade" signifies that the niacin meets stringent purity and quality standards required for use in medicinal products and dietary supplements, ensuring its suitability for human consumption or therapeutic applications.

Distinguishing this subcategory from its sibling, 2936.29.16.20 (Other), is the emphasis on the intended use and quality. While the "Other" category might encompass niacin or its derivatives not specifically meeting pharmaceutical grade standards, or those intended for different industrial applications, this classification is narrowly defined for high-purity niacin destined for the pharmaceutical and health supplement industries.

As this node is a leaf node, there are no further subcategories. Classification at this level is determined by the identification of niacin itself and its certification as pharmaceutical grade. Importers and exporters should ensure that documentation clearly indicates this grade to facilitate accurate customs processing under this specific tariff heading.
