3002.90.10.00 - Ferments

This HTS classification, 3002.90.10.00, specifically designates "Ferments" within the broader category of human blood, animal blood, antisera, immunological products, vaccines, toxins, and microbial cultures. Ferments, in this context, refer to substances produced by living organisms, particularly micro-organisms like bacteria or yeasts, that act as catalysts in chemical reactions. This typically includes enzymes and enzyme preparations used for various industrial, diagnostic, or therapeutic applications.

Unlike its sibling category 3002.90.52 ("Other"), which serves as a residual classification for products within Chapter 3002 not specifically enumerated elsewhere, 3002.90.10.00 provides a distinct and precise designation for ferments. This ensures that goods with a clear fermentative origin and function are correctly identified and taxed, rather than being commingled with other diverse immunological products or cultures. The key differentiator lies in the active, catalytic property derived from biological processes.

As this is a leaf node within the HTS structure, there are no further subcategories. Therefore, classification into 3002.90.10.00 hinges on the product being a ferment, characterized by its biological origin and enzymatic or catalytic action. Examples include specific digestive enzymes used in pharmaceuticals or industrial processing, as well as diagnostic enzyme kits where the active component is a ferment.
