0303.12.00.52 - Coho (silver)

This HTS classification, 0303.12.00.52, specifically designates frozen coho (silver) salmon. Within the broader category of frozen salmonidae, this subheading distinguishes coho salmon from other Pacific species based on its scientific classification and common market names. The goods classified here are whole, headless, or gutted fish, but not fillets or other meat of fish falling under heading 0304.

Coho salmon, scientifically known as *Oncorhynchus kisutch*, is differentiated from its siblings by its unique biological characteristics and market identity. For instance, it is distinct from Chinook (king) salmon (*Oncorhynchus tschawytscha*), Chum (dog) salmon (*Oncorhynchus keta*), and Pink (humpie) salmon (*Oncorhynchus gorbuscha*), each of which are assigned their own specific subheadings. When classifying frozen salmon, it is crucial to identify the species to ensure accurate duty application.

As this subheading is a leaf node in the HTS structure, there are no further subdivisions. Therefore, classification under 0303.12.00.52 is final for frozen coho salmon that meets the criteria outlined in the parent categories. Importers and exporters should ensure that their documentation clearly identifies the salmon as "coho" or "silver" to align with this specific tariff provision.
