0302.51.00 - Cod (Gadus morhua, Gadus ogac, Gadus macrocephalus)

This HTS classification covers fresh or chilled cod, specifically the species *Gadus morhua*, *Gadus ogac*, and *Gadus macrocephalus*. These are whole, unprocessed fish belonging to the Gadidae family, distinguished by their three dorsal fins and two anal fins, and are typically found in the North Atlantic and North Pacific oceans. This category is distinct from other classifications within heading 0302 that cover different types of fish from the same families, such as haddock (0302.52.00.00), coalfish (0302.53.00.00), hake (0302.54), or Alaska pollock (0302.55).

Further subdivision within this category allows for a more precise classification of the cod. Subheading 0302.51.00.10 is designated for Atlantic cod, identifying the specific geographic origin of *Gadus morhua* found in the Atlantic Ocean. The alternative subheading, 0302.51.00.90, serves as a catch-all for any other cod falling under this heading that is not specifically designated as Atlantic. This detailed breakdown is crucial for accurate trade data collection and customs procedures.
