0306.19.01.30 - Antarctic krill (Euphausia superba)

This HTS classification covers frozen Antarctic krill, specifically identified by the scientific name *Euphausia superba*. These small, shrimp-like crustaceans are caught in the waters of the Southern Ocean and are typically processed and frozen for various end uses, including human consumption as food products and as feed for aquaculture or other animals. The classification is specific to the frozen state of this particular species.

At this level of detail, it is important to distinguish Antarctic krill from other frozen crustaceans. For example, sibling category 0306.19.01.10 specifically covers freshwater crawfish, which are distinct in species and origin from marine krill. Category 0306.19.01.61, "Other," would encompass any other frozen crustaceans not otherwise specified within the broader "Other" designation for frozen crustaceans, making Antarctic krill a distinct and separately classified item.

As this is a leaf node, there are no further subcategories for Antarctic krill. The classification ends here, meaning that once a product is identified as frozen Antarctic krill (*Euphausia superba*), it falls definitively under HTS code 0306.19.01.30, provided it meets the general conditions of Chapter 3 and the preceding headings for crustaceans. Classification relies on the accurate identification of the species and its frozen state.
