0304.83.10.15 - Sole

This HTS classification covers frozen fillets of flat fish, specifically those belonging to the families Pleuronectidae, Bothidae, Cynoglossidae, Soleidae, Scophthalmidae, and Citharidae. The key characteristics for this category are that the fillets must be skinned, can be divided into pieces, and are frozen into blocks each weighing over 4.5 kg. Furthermore, these blocks are intended for subsequent mincing, grinding, or cutting into pieces of uniform weights and dimensions.

The distinction from sibling categories lies in the specific species of flat fish and the intended end-use. For instance, 0304.83.10.10 specifically refers to Greenland turbot, while 0304.83.10.20 covers flounder. This category, "Other," encompasses all other types of flat fish not otherwise specified, provided they meet the stringent processing and packaging requirements outlined. The focus is on the preparation for further industrial processing into more refined fish products.

As this is a leaf node in the HTS classification, there are no further subcategories. Therefore, the classification is final for products meeting all the specified criteria. Importers and exporters should ensure that the frozen flat fish fillets meet all the conditions, including the weight of the blocks and the stated intention for subsequent mincing, grinding, or cutting into uniform pieces, to ensure correct classification.
