0307.72.00 - Frozen

This HTS category, 0307.72.00, specifically covers clams, cockles, and ark shells that have been preserved through freezing. This classification applies regardless of whether the mollusks are presented in their shell or shelled, as long as the primary state of preservation is frozen. It encompasses products where the freezing process is intended to maintain the quality and extend the shelf life of these bivalve mollusks.

It is important to distinguish this category from its sibling, 0307.71.00, which covers the same types of mollusks but in their live, fresh, or chilled states. The key differentiator is the method of preservation; this category applies only when the product has undergone a freezing process. The sibling category, 0307.79.01, serves as a catch-all for other forms of preparation or preservation not specifically enumerated elsewhere within this parent group.

Within this frozen classification, further subdivisions exist to specify particular types or presentations. The subcategory 0307.72.00.60, for instance, addresses "Other" frozen clams, cockles, and ark shells that do not fall into more specific subheadings. These subdivisions allow for a more granular classification, often based on the species of mollusk or the specific processing methods employed beyond simple freezing.
