0303.11.00.00 - Sockeye salmon (red salmon) (Oncorhynchus nerka)

This HTS classification, 0303.11.00.00, specifically identifies frozen sockeye salmon, also known as red salmon, scientifically classified as *Oncorhynchus nerka*. This category falls under the broader group of frozen fish, excluding fillets and other fish meat, and more narrowly within the Salmonidae family, excluding edible fish offal. The key distinguishing feature of this classification is the precise species of salmon being imported or exported.

It is crucial to differentiate this classification from its siblings. While 0303.12.00 covers various other Pacific salmon species like pink, chum, chinook, coho, masou, and cherry salmon, and 0303.13.00.00 pertains to Atlantic salmon and Danube salmon, this code is solely for *Oncorhynchus nerka*. Similarly, 0303.14.00.00 is reserved for trout species, and 0303.19.01.00 serves as a catch-all for any other Salmonidae not otherwise specified.

As a leaf node, 0303.11.00.00 does not have further subcategories. Therefore, classification under this heading relies entirely on the accurate identification of the imported product as frozen sockeye salmon (*Oncorhynchus nerka*). Importers and exporters should ensure their documentation clearly specifies this species to avoid misclassification and potential customs delays or penalties.
