0303.89.00.70 - Grouper

This HTS classification, 0303.89.00.70, specifically covers frozen grouper. Grouper, a type of marine fish belonging to the Epinephelinae subfamily, is distinguished by its relatively large mouth and robust body. This category falls under the broader heading of "Fish, frozen, excluding fish fillets and other fish meat of heading 0304," and more specifically, "Other fish, excluding edible fish offal of subheadings 0303.91 to 0303.99."

Within the "Other fish" category, 0303.89.00.70 is differentiated from its sibling categories by the specific species it represents. While other sibling entries classify distinct fish like smelts, cusk, shad, sturgeon, and Atka mackerel, this code isolates frozen grouper for precise tariff application. The distinction relies on the biological identification of the species, as different fish, even when similarly presented (frozen, whole, or in pieces), are subject to varied trade regulations and duties.

As a leaf node, this classification does not contain further subcategories. Therefore, the primary classification criterion for goods falling under 0303.89.00.70 is the definitive identification of the fish as grouper, in a frozen state, and not as fillets or other fish meat classified under heading 0304. Importers and exporters must ensure accurate species identification to correctly apply this tariff code.
