Statistical number 12 of 13 in subheading 030483
The residual provision HTS 0304831090 captures skinned frozen flatfish fillet blocks over 4.5 kg destined for further processing that are not specifically enumerated elsewhere — meaning species such as plaice, turbot (non-Greenland), dab, or other flatfish fall here when no dedicated line applies. Because this is a catch-all line, correct classification requires ruling out all named flatfish provisions first, making species identification and a systematic HTS analysis essential before entry. The industrial block format and processing-intent requirement mirror those of the species-specific lines in the same subheading group. FDA seafood HACCP regulations and acceptable market-name requirements apply regardless of species.

The importer should work through the HTS schedule in order: check whether the species qualifies as Greenland turbot (0304831010), sole (0304831015), flounder (0304831020), or halibut other than Greenland (0304831025). Only after ruling out each named provision does 0304831090 apply. A binding ruling request to CBP is advisable for novel or ambiguously named species.
Plaice (Pleuronectes platessa) and European turbot (Scophthalmus maximus) are not named in the specific flatfish lines of this subheading group, so they would generally fall under 0304831090 when imported as skinned frozen blocks over 4.5 kg for processing. Importers should confirm species identity with scientific documentation and consider a CBP ruling for certainty.
