0302.34.00.00 - Bigeye tunas (Thunnus obesus)

This HTS classification, 0302.34.00.00, specifically covers bigeye tunas (scientific name: *Thunnus obesus*) that are imported in a fresh or chilled state. This category falls under the broader heading of fish, fresh or chilled, excluding fillets and other fish meat, and further refines the classification within the subheadings dedicated to various types of tuna. The defining characteristic for inclusion here is the species identification as *Thunnus obesus*, commonly known as bigeye tuna.

Distinguishing this classification from its siblings requires a focus on the specific tuna species. For instance, it is differentiated from albacore tuna (*Thunnus alalunga*) under 0302.31.00.00, yellowfin tuna (*Thunnus albacares*) under 0302.32.00.00, and skipjack tuna (*Katsuwonus pelamis*) under 0302.33.00.00. It is also distinct from the various bluefin tuna classifications, such as Atlantic and Pacific bluefin tunas (0302.35.01.00) and southern bluefin tunas (0302.36.00.00). The classification of bigeye tuna is based on the accepted scientific and common names of the species.

As this is a leaf node within the HTS structure, there are no further subcategories or subdivisions under 0302.34.00.00. Therefore, all fresh or chilled bigeye tunas that meet the criteria of heading 0302 will be classified directly under this specific code. Importers and customs officials should rely on clear species identification to ensure accurate classification and avoid misclassification with other tuna species.
