3002.12.00 - Antisera and other blood fractions

This HTS category, 3002.12.00, specifically encompasses antisera and other blood fractions. Antisera are preparations containing antibodies, typically derived from the blood of immunized animals or humans, and are used therapeutically to neutralize toxins or combat infections. "Other blood fractions" refers to components of blood, such as albumin or globulins, that have been isolated and prepared for therapeutic, prophylactic, or diagnostic uses. This heading covers these biological products regardless of whether they have been modified or were obtained through biotechnological processes.

It is crucial to differentiate this heading from its siblings. While 3002.12.00 focuses on specific preparations like antisera and other blood fractions, its siblings, 3002.13.00, 3002.14.00, and 3002.15.00, all pertain to "Immunological products." The key distinction lies in the form and presentation: 3002.13.00 and 3002.14.00 cover unmixed and mixed immunological products respectively, provided they are not put up in measured doses or for retail sale, whereas 3002.15.00 covers immunological products that *are* presented in measured doses or for retail sale.

The subcategories within 3002.12.00 further delineate specific types of blood-derived products. These include human blood plasma, normal human blood sera, human immune blood sera, and Fetal Bovine Serum (FBS), alongside a residual category for "Other" blood fractions. This hierarchical structure allows for precise classification based on the origin (human or animal), the specific component of blood, and its intended application, ensuring accurate tariff treatment for these critical biological materials.
