0304.82.10.00 - Skinned, whether or not divided into pieces, and frozen into blocks each weighing over 4.5 kg, imported to be minced, ground or cut into pieces of uniform weights and dimensions

This HTS classification, 0304.82.10.00, specifically covers frozen fillets of certain trout species that have been skinned and may be divided into pieces. The defining characteristic for this subcategory is their presentation: they are frozen into blocks exceeding 4.5 kg, with the explicit intention of being further processed by mincing, grinding, or cutting into pieces of uniform weights and dimensions. This preparation signifies a subsequent stage in the value chain, moving beyond simple preservation to facilitate specific culinary or manufacturing applications.

This classification distinguishes itself from its sibling category, 0304.82.50.00 ("Other"). While both fall under frozen fillets of trout, the "Other" category would encompass any frozen trout fillets not meeting the specific processing criteria outlined in 0304.82.10.00. Therefore, if the frozen trout fillets are not presented in blocks over 4.5 kg intended for further uniform processing, they would likely be classified under the broader "Other" designation.

As this node is a leaf node within the HTS structure, there are no further subcategories. Classification under 0304.82.10.00 is the final determination for frozen, skinned trout fillets that are prepared in blocks exceeding 4.5 kg for subsequent uniform mincing, grinding, or cutting. The critical factors for classification are the species of trout, the frozen state, the skinless condition, the block weight, and the intended use for precise portioning.
