0304.75.10.00 - 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 category, 0304.75.10.00, specifically classifies frozen Alaska pollock (Theragra chalcogramma) fillets that have been prepared for further processing. The key distinguishing features are that these fillets are skinned, may be divided into pieces, and are frozen into blocks exceeding 4.5 kg. Crucially, these blocks are imported with the explicit intention of being minced, ground, or cut into pieces of uniform weights and dimensions. This preparation signifies that the product is not intended for direct consumption in its block form but is destined for further manufacturing into value-added products.

The primary distinction between this subcategory and its sibling, 0304.75.50.00 (Other), lies in the specific processing and intended use. While both fall under frozen fillets of Alaska pollock, the "Other" category would likely encompass fillets that are not specifically prepared in the specified block format for further size and weight standardization through mincing, grinding, or precise cutting. This means 0304.75.10.00 is for semi-finished products geared towards industrial processing, whereas 0304.75.50.00 might include frozen fillets in various other forms or intended for different downstream applications.

As this is a leaf node within the HTS classification structure, there are no further subcategories. The classification terminates here, focusing solely on the described attributes of skinned, frozen Alaska pollock fillets in blocks exceeding 4.5 kg, intended for mincing, grinding, or precise cutting. This level of detail ensures precise tariff application for these specific types of imported fish products.
