3002.42.00.00 - Vaccines for veterinary medicine

This HTS category encompasses vaccines specifically prepared for use in veterinary medicine. These biological preparations are designed to stimulate an immune response in animals, thereby preventing or treating diseases. They are distinct from vaccines intended for human use, which are classified under a separate subheading.

The primary differentiator for this category is the intended recipient of the vaccine. While both human and veterinary vaccines fall under the broader heading of "Vaccines, toxins, cultures of micro-organisms (excluding yeasts) and similar products," the distinction is crucial for tariff and regulatory purposes. This subheading is exclusively for products administered to livestock, pets, and other animals.

As this is a leaf node within the HTS structure, there are no further subcategories. Classification within 3002.42.00.00 is determined by the documented purpose and target species for the vaccine. Examples include vaccines against common animal diseases such as rabies, distemper, or avian influenza, provided they are solely intended for veterinary application.
