Flatfish not elsewhere specified in the US tariff schedule — covering families Pleuronectidae, Bothidae, Cynoglossidae, Soleidae, Scophthalmidae, and Citharidae — enter under the residual NESOI lines when shipped fresh or chilled in whole or dressed form. The US schedule subdivides this residual category into flounder (0302290110) and all other qualifying flatfish (0302290190), with an older consolidated line (0302290100) also present. Correct classification requires first confirming the species does not belong to a named heading (halibut, plaice, sole, or turbot), then determining whether it qualifies as flounder. FDA HACCP requirements and acceptable market name rules apply across all lines in this group.

Classification follows a hierarchical exclusion process: first check whether the species is halibut (0302210000 group), plaice (0302220000), sole (0302230000), or turbot (0302240000). Only if the species is not covered by those named headings does it fall into the NESOI residual. Within the NESOI group, flounder is further separated at 0302290110, with all remaining qualifying flatfish families at 0302290190.
Yes, particularly for less familiar species. FDA maintains a list of acceptable market names for seafood, and using an unapproved or misleading common name — for example, labeling a non-sole flatfish as 'sole' — can constitute misbranding. Importers of NESOI flatfish should confirm the FDA-accepted market name for each species before finalizing retail or foodservice labeling.
