0302.29.01.90 - Other

This HTS category, "Other," within the classification of flat fish (excluding fillets and edible offal), serves as a residual classification for flat fish that do not fall under more specific subheadings. It encompasses a variety of flat fish species belonging to the families Pleuronectidae, Bothidae, Cynoglossidae, Soleidae, Scophthalmidae, and Citharidae, which are imported or exported in fresh or chilled condition. The key characteristic for inclusion here is that the fish are whole, have been gutted, or are presented in a form other than fillets or meat of subheading 0304.

This subheading is distinct from its sibling, 0302.29.01.10, which specifically designates "Flounder." Therefore, any flat fish species that are not classified as flounder, but meet the general criteria for fresh or chilled flat fish, will be classified under this "Other" designation. This ensures that all flat fish, except those explicitly named or falling into offal categories, are accounted for within the tariff schedule.

As this is a leaf node, there are no further subcategories within 0302.29.01.90. Classification at this level relies on a process of elimination, meaning that if a flat fish is fresh or chilled, belongs to one of the specified families, is not a fillet or meat of subheading 0304, and is not specifically identified as flounder, it will be classified under this residual "Other" category. Proper identification of the species and its presentation form is crucial for accurate classification.
