0307.92.01.30 - Conch

This HTS classification, 0307.92.01.30, specifically designates frozen conch. The classification falls under the broader category of "Other molluscs, whether in shell or not, live, fresh, chilled, frozen, dried, salted or in brine; smoked molluscs, whether in shell or not, whether or not cooked before or during the smoking process." The key defining characteristic here is that the conch must be preserved through freezing.

Within the "Frozen" subcategory for "Other molluscs," this specific code distinguishes conch from other types of frozen molluscs. While its sibling category, 0307.92.01.90, covers "Other" frozen molluscs not otherwise specified, this code is exclusively for conch. This indicates a need to differentiate conch, often characterized by its large, spiral shell and edible meat, from a diverse range of other frozen molluscs like snails, clams, or mussels that might fall under the general "Other" designation.

As this is a leaf node, there are no further subcategories under 0307.92.01.30. Therefore, the classification is definitive for conch that has been frozen. Classification relies on the correct identification of the commodity as conch and its preservation state as frozen, adhering to the established nomenclature and exclusion criteria of the Harmonized Tariff Schedule.
