0304.89.50.03 - Yellow perch

This HTS category, 0304.89.50.03, specifically classifies frozen fillets of yellow perch. Yellow perch, scientifically known as *Perca flavescens*, refers to the fillets derived from this particular species of freshwater fish. The classification is applied when these fillets are imported or exported in a frozen state.

It is important to distinguish this classification from its siblings. Category 0304.89.50.06 covers pike perch, which, despite the inclusion of "yellow pike" in its description, refers to a distinct species from the yellow perch classified here. Category 0304.89.50.09, designated as "Other," is reserved for any other frozen fish fillets that do not fall under the more specific preceding categories within the "Other" and "Fresh-water fish" groupings.

As this node represents a leaf category within the HTS structure, there are no further subcategories. Therefore, classification at this level is final for frozen yellow perch fillets. The defining characteristic for classification under 0304.89.50.03 is the species of fish (yellow perch) and its presentation (frozen fillets).
