0302.32.00.00 - Yellowfin tunas (Thunnus albacares)

This HTS category, 0302.32.00.00, specifically classifies fresh or chilled yellowfin tunas, scientifically identified as *Thunnus albacares*. These fish are characterized by their distinctive yellow dorsal and anal fins. This classification falls under the broader heading of fresh or chilled fish, excluding fish fillets and other fish meat of heading 0304, and further narrows down to tunas and skipjack tuna.

The distinction between yellowfin tuna and its sibling categories lies in the species of tuna. For instance, 0302.31.00.00 covers albacore or long-finned tunas (*Thunnus alalunga*), which are differentiated by their unusually long pectoral fins. Similarly, 0302.33.00.00 pertains to skipjack tuna (*Katsuwonus pelamis*), easily identifiable by the striped, elongated markings on its underside. Other sibling categories, such as bigeye tuna (0302.34.00.00) and various bluefin tuna species, are distinguished by their unique physical attributes like head size and fin configurations, as well as their specific scientific nomenclature.

As this HTS code represents a leaf node, there are no further subcategories to introduce. Therefore, classification under 0302.32.00.00 is definitive for fresh or chilled specimens of yellowfin tuna meeting the descriptive criteria of the species. The crucial factor for correct classification rests on accurate species identification, distinguishing *Thunnus albacares* from other tuna species listed within the same parent heading.
