0303.41.00.00 - Albacore or longfinned tunas (Thunnus alalunga) 🖩

This HTS classification, 0303.41.00.00, specifically covers frozen albacore or longfinned tunas, scientifically known as *Thunnus alalunga*. These are distinct species of tuna characterized by their exceptionally long pectoral fins. The classification applies to the whole fish, frozen, and excludes any processed forms like fillets or other meat products that would fall under heading 0304. This category is situated within the broader classification of frozen fish, specifically under frozen tunas and skipjack tuna.

It is crucial to differentiate this category from its siblings. For instance, 0303.42.00.00 is for yellowfin tunas (*Thunnus albacares*), which have shorter pectoral fins. Similarly, 0303.43.00.00 identifies skipjack tuna (*Katsuwonus pelamis*), another common tuna species. Other sibling categories encompass bigeye tunas, Atlantic and Pacific bluefin tunas, and southern bluefin tunas, each defined by their unique species and scientific classification. This specific HTS code ensures precise tracking and tariff application for albacore tuna as distinct from these other valuable tuna species.

As this is a leaf node within the HTS, there are no further subcategories. Therefore, the classification is definitive for frozen whole albacore or longfinned tunas. When classifying, it is important to confirm the species identification based on distinguishing physical characteristics, such as the significant length of the pectoral fins compared to the body, to ensure accurate classification under 0303.41.00.00 and not a different tuna species.
