0207.45.00.20 - Livers

This HTS category, 0207.45.00.20, specifically covers frozen livers originating from ducks. These are the edible internal organs of ducks, processed and preserved through freezing for trade purposes. The classification is focused on the biological origin and the state of preservation of the product, ensuring accurate identification for customs and trade.

Within the broader category of "Other, frozen" poultry offal of ducks (0207.45), this specific subheading distinguishes itself by its focus solely on the liver. Its sibling category, 0207.45.00.40, designated as "Other," would encompass any other frozen edible offal of ducks that are not livers, such as hearts or gizzards, according to their respective definitions.

As this is a leaf node within the HTS structure, there are no further subdivisions. Therefore, classification under 0207.45.00.20 is final for frozen duck livers. Importers and exporters should ensure that the product's documentation clearly identifies the item as duck liver and that it has been preserved through freezing to qualify for this specific tariff line.
