3002.12.00.90 - Other

This category, HTS 3002.12.00.90, encompasses "Other" antisera and other blood fractions not specifically enumerated within its sibling categories. It serves as a residual classification for immunological products derived from blood that do not fit the precise descriptions of human blood plasma, normal human blood sera, human immune blood sera, or Fetal Bovine Serum (FBS). The products classified here are typically complex biological substances intended for therapeutic, prophylactic, or diagnostic applications.

The distinction from sibling categories is crucial for accurate classification. While 3002.12.00.10 covers the liquid component of blood containing clotting factors, and 3002.12.00.20 and 3002.12.00.30 specifically address normal and immune human blood sera respectively, this "Other" category captures a broader range of blood-derived immunological preparations. Similarly, it differs from 3002.12.00.40, which is exclusively for serum derived from bovine fetuses, a common reagent in cell culture.

As a leaf node, HTS 3002.12.00.90 has no further subcategories. Classification into this code requires careful consideration of the specific nature of the blood fraction or antiserum, its origin, its preparation methods, and its intended use. Importers should refer to specific product literature and, if necessary, consult with customs authorities to ensure correct classification for any blood-derived immunological product not explicitly listed elsewhere within heading 3002.
