0303.81.00.91 - Other

This HTS category, 0303.81.00.91, encompasses "Other" frozen fish within the broader group of "Dogfish and other sharks." Following the hierarchical structure, it captures frozen fish that meet the definition of dogfish or sharks but are not specifically classified under the sibling category for "Dogfish (Squalus spp.)". This implies that while the primary characteristic is being a shark species, the specific classification here is for those sharks that do not fall under the more narrowly defined "Squalus spp." designation.

The distinction between this category and its sibling, 0303.81.00.11, hinges on the precise scientific identification of the shark species. When a shipment contains frozen dogfish or other shark species that are not definitively identified or classified as *Squalus spp.*, they will be directed to this "Other" subcategory. This ensures accurate tariff application for the wide diversity of shark species entering international trade.

As this is a leaf node within the HTS classification system, there are no further subcategories. Therefore, the classification concludes at this point, with the importer or exporter responsible for ensuring the shipment aligns with the broader definition of dogfish and other sharks, excluding those specifically identified as *Squalus spp.*.
