0304.89.50.09 - Other

This classification, "Other" for frozen fillets of other fish, fresh-water fish, and perch, serves as a residual category for perch fillets that do not fall under more specific classifications. It is intended to capture frozen perch fillets derived from species not explicitly listed in the sibling categories.

This "Other" category is distinguished from its siblings, "Yellow perch" (0304.89.50.03) and "Pike perch (including yellow pike)" (0304.89.50.06), by its lack of specific species identification. While the sibling categories denote distinct species of perch, this category encompasses any frozen perch fillets not meeting those precise species definitions.

As this is a leaf node within the HTS structure, there are no further subcategories. Classification within this code will rely on careful examination of the fish species to ensure it is indeed a perch and that it does not fit the more defined sibling categories. The frozen state and fillet form are prerequisites for classification under this parent heading (0304).
