0304.89.10.90 - Other

This HTS classification, 0304.89.10.90, encompasses frozen fillets of fish, other than those specifically enumerated, that have been skinned and are frozen into blocks exceeding 4.5 kilograms each. A key defining characteristic for this category is the intended use of these frozen blocks: they are imported for the express purpose of being minced, ground, or further cut into pieces of uniform weights and dimensions. This distinction is crucial for importers and customs officials to accurately classify the product based on its post-import processing.

The "Other" designation at this level signifies that these frozen fish blocks do not fall under the more specific sibling categories, such as Ocean Catfish (Wolf Fish), Pickerel, Sauger, or Perch. While all are frozen fish fillets destined for further processing, the specific species or type of fish dictates their placement within the tariff schedule. Therefore, if the imported frozen fish blocks are not comprised of those specifically listed species, they would likely fall under this general "Other" classification.

As this is a leaf node within the HTS structure, there are no further subcategories. Classification under 0304.89.10.90 is final at this point, provided all preceding criteria, including the origin of the fish, its form (skinned fillets frozen in blocks), weight of the blocks, and intended use for mincing/grinding/uniform cutting, are met. The primary classification drivers remain the physical state of the product, its packaging format, and its intended downstream processing.
