0303.89.00.40 - Tilapias, other than Oreochromis spp.

This HTS category encompasses frozen fish classified under heading 0303, specifically freshwater fish falling into the broader group of "Other fish" (0303.89). The defining characteristic of this classification is the inclusion of tilapias, excluding those belonging to the *Oreochromis* species. These are typically whole frozen fish or fish presented in a manner that does not constitute fillets or other meat of heading 0304.

This specific classification, 0303.89.00.40, distinguishes itself from its sibling categories by its precise focus on non-*Oreochromis* tilapia species. For instance, it is distinct from 0303.89.00.28 (Pike and pickerel), 0303.89.00.31 (Perch and pike perch), 0303.89.00.34 (Sauger), and 0303.89.00.37 (Whitefish), all of which represent different genera and species of freshwater fish. While 0303.89.00.43 is also an "Other" category, this specific code targets the distinct tilapia species as defined.

As this is a leaf node in the HTS classification, there are no further subcategories. The classification is therefore dependent on accurately identifying the species as tilapia and ensuring it is not an *Oreochromis* species, and that the product is presented in a frozen state, excluding fillets and fish meat. This level of specificity ensures precise import and export documentation for trade purposes.
