0303.81.00 - Dogfish and other sharks

This HTS category, 0303.81.00, encompasses frozen dogfish and other sharks intended for human consumption. These fish are distinguished from other frozen fish by their unique biological classification as sharks, a group separate from rays, skates, sea bass, and other miscellaneous fish species within the broader "Other fish" subheadings. The inclusion of "other sharks" ensures that all non-dogfish shark species that fall under the frozen fish provisions of heading 0303 are correctly classified here.

This classification is important for differentiating between various cartilaginous fish and bony fish when imported frozen. Unlike the sibling category 0303.82.00.00, which specifically covers rays and skates (both elasmobranchs but distinct families), or 0303.83.00.00 for toothfish and 0303.84.00.00 for sea bass, this heading focuses solely on the shark order.

The subcategories within 0303.81.00.00 provide further granularity. Specifically, 0303.81.00.11 isolates frozen dogfish (Squalus spp.), allowing for more precise statistical tracking and potential tariff distinctions for this particular type of shark. The remaining dogfish and other sharks are then classified under the residual subheading 0303.81.00.91, ensuring comprehensive coverage within this shark classification.
