0309.90.50.30 - Conch

This HTS classification, 0309.90.50.30, specifically covers frozen conch that is intended for human consumption. The goods fall under the broader category of flours, meals, and pellets of molluscs, crustaceans, and other aquatic invertebrates, but are distinguished by their physical form and preservation method. This particular subheading is for the frozen product, excluding any further processed forms like flours or meals.

The primary sibling category at this level, 0309.90.50.90, pertains to "Other" types of molluscs within the frozen category. Therefore, 0309.90.50.30 acts as a specific designation for conch, differentiating it from other frozen molluscan species that might be classified under the general "Other" subheading. This level of detail ensures precise tariff application based on the specific species of mollusc.

As this is a leaf node within the HTS structure, there are no further subcategories under 0309.90.50.30. Classification terminates at this point, indicating that all frozen conch fit for human consumption, regardless of preparation beyond freezing, would be entered under this code. This provides a definitive classification for this specific seafood product.
