2936.29.16.20 - Other

This HTS category, 2936.29.16.20, encompasses niacin (nicotinic acid) that is not specifically classified as "pharmaceutical grade." Niacin is a B vitamin essential for human and animal health, playing a crucial role in metabolism and cellular function. It is commonly used in food fortification, animal feed supplements, and as a dietary supplement.

The primary distinction for this category lies in the intended application and purity standards. Unlike the "pharmaceutical grade" sibling, which is reserved for niacin intended for medicinal use and subject to stringent regulatory requirements, this classification applies to niacin intended for less regulated applications such as industrial uses, general food fortification where specific pharmaceutical standards are not mandated, or as a component in animal feed. The physical form, chemical purity, and regulatory approvals will determine if niacin falls into the pharmaceutical grade or this "other" category.

As this is a leaf node in the HTS classification, there are no further subcategories. Therefore, the classification hinges entirely on the precise definition of "pharmaceutical grade" versus "other" applications for niacin. Importers must carefully consider the end-use and any accompanying documentation to ensure accurate classification.
