0304.74.10.00 - 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 (0304.74.10.00) specifically covers frozen fillets of hake (belonging to the genera Merluccius or Urophycis) that have been skinned. Crucially, these fillets must be imported in blocks weighing over 4.5 kg and intended for further processing, such as mincing, grinding, or cutting into pieces of uniform weights and dimensions. This detailed specification ensures that only hake fillets destined for these particular manufacturing processes are classified here.

Distinguishing this category from its sibling, 0304.74.50.00 "Other," is vital. The "Other" category would encompass frozen hake fillets that do not meet the specific processing criteria outlined in 0304.74.10.00. This could include whole frozen hake fillets not intended for further mincing or uniform cutting, or fillets imported in smaller packaging or with different processing intentions. Therefore, the key differentiator lies in the state of preparation and the intended downstream use of the frozen hake fillets.

As this is a leaf node within the HTS structure, there are no further subcategories. Classification under 0304.74.10.00 is final for products meeting all the specified criteria. Importers must ensure that their frozen hake fillets conform to the requirement of being skinned, frozen in blocks over 4.5 kg, and designated for mincing, grinding, or cutting into uniform pieces to correctly utilize this specific tariff line.
