0304.81.10.00 - 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, 0304.81.10.00, specifically covers frozen fillets of certain salmon species, including Pacific salmon (various Oncorhynchus species), Atlantic salmon (Salmo salar), and Danube salmon (Hucho hucho). The key defining characteristics for this classification are that the fillets are skinned, frozen into blocks exceeding 4.5 kg, and are intended for further processing such as mincing, grinding, or cutting into uniform weights and dimensions. This precise processing requirement distinguishes these goods for specific industrial applications.

The primary distinction from its sibling category, 0304.81.50, lies in the intended further processing. While 0304.81.50 likely encompasses frozen salmon fillets not meeting the specific processing criteria outlined here, this classification is reserved for products prepared for precise, value-added downstream manufacturing. Therefore, the defining elements are the block weight, the frozen state, and the explicit purpose of subsequent precise cutting or processing.

As this is a leaf node within the HTS, there are no further subcategories. All goods meeting the detailed criteria of skinned, frozen block salmon fillets exceeding 4.5 kg, destined for mincing, grinding, or uniform cutting, will fall under this specific subheading. The classification is absolute at this level, based on the physical state and intended end-use of the salmon product.
