0308.90.01.00 - Other

This HTS category, "Other," under the broader heading of aquatic invertebrates not classified as crustaceans or mollusks, serves as a residual classification for a diverse group of marine life. It encompasses live, fresh, chilled, frozen, dried, salted, brined, or smoked aquatic invertebrates that do not fall under more specific subheadings within Chapter 308. This includes creatures such as various species of worms, marine sponges, and other less commonly traded or distinctly categorized marine organisms.

It is crucial to distinguish this category from its siblings. Unlike sea cucumbers, sea urchins, or jellyfish, which have dedicated subheadings due to their commercial significance and distinct characteristics, the "Other" category captures those aquatic invertebrates that lack such specific classifications. For instance, while sea cucumbers and sea urchins are echinoderms, and jellyfish are cnidarians, this "Other" category might include other phyla of marine invertebrates with unique biological structures and uses.

As this is a leaf node, there are no further subcategories. Therefore, classification into this subheading relies on a thorough exclusion of all other more specific categories for aquatic invertebrates. Importers and exporters must carefully examine the biological classification and presentation of their goods to ensure they are not inadvertently placed here when a more precise tariff code exists. This often involves consulting taxonomic guides and verifying the absence of the goods within more narrowly defined classifications of aquatic invertebrates.
