3002.90.52 - Other

This HTS category, 3002.90.52, falls under "Other" within the broader heading for human blood, animal blood, antisera, and immunological products. It encompasses a range of biological products not specifically enumerated in other subheadings. This classification is particularly relevant for biological preparations derived from blood or microbial cultures that do not fit into more narrowly defined categories.

Distinguishing this category from its sibling, 3002.90.10 (Ferments), is crucial. While ferments are specific biological catalysts often used in industrial or medical processes, this "Other" category is more expansive, including a wider array of immunological or diagnostic materials. The key differentiator lies in the specific biological origin and intended use, with ferments having a more focused enzymatic function.

Within this "Other" classification, further subdivisions exist to refine the scope. Subheadings like 3002.90.52.10 for whole human blood, 3002.90.52.20 for antiallergenic preparations, and 3002.90.52.50 for other miscellaneous products clarify the diversity of items that can be classified here. These subcategories highlight the importance of precise identification of the product's nature, its source, and its specific therapeutic, prophylactic, or diagnostic application for accurate customs reporting.
