0307.79.01.60 - Other

This HTS category, "Other," within the classification for clams, cockles, and ark shells, serves as a residual classification for bivalve mollusks belonging to the specified families (Arcidae, Arcticidae, Cardiidae, Donacidae, Hiatellidae, Mactridae, Mesodesmatidae, Myidae, Semelidae, Solecurtidae, Solenidae, Tridacnidae, and Veneridae) that are not specifically categorized under the sibling "Clams" designation. This encompasses a broad range of species within these families that meet the definition of cockles or ark shells.

Given that "Clams" is a distinct sibling category, this "Other" classification primarily encompasses those species identified as cockles or ark shells. Classification into this category hinges on the biological identification of the mollusk as belonging to one of the listed families and fitting the common culinary or commercial definition of a cockle or ark shell, rather than a clam.

As this is a leaf node, there are no further subcategories. Therefore, the classification for any given product falling under this HTS code relies on verifying that the mollusk is live, fresh, chilled, frozen, dried, salted, in brine, or smoked, and that it belongs to the specified families and is not a clam. The primary determining factor is the species identification and its alignment with the common understanding of "cockles and ark shells."
