0309.90 - Other:

This category, HTS 0309.90, encompasses flours, meals, and pellets derived from aquatic invertebrates, excluding fish, that are suitable for human consumption. This broadly includes products made from a variety of crustaceans and molluscs, processed into fine powders, granular forms, or pelletized shapes. The key criterion for inclusion here is the origin from non-fish aquatic invertebrates and their intended use as food ingredients or finished food products.

Distinguishing this category from its sibling, 0309.10, is crucial. While 0309.10 specifically covers flours, meals, and pellets originating from fish, HTS 0309.90 is reserved for those derived from other aquatic life. This means any processed products from shrimp, crab, lobster, oysters, mussels, clams, or other similar non-fish aquatic invertebrates fall under this classification, provided they meet the criteria of being flour, meal, or pellets and are fit for human consumption.

Within HTS 0309.90, further subdivisions exist to refine classification. These typically differentiate based on the specific type of invertebrate, such as crustaceans or molluscs. The residual category, 0309.90.90.00, serves as a catch-all for any other flours, meals, or pellets of aquatic invertebrates, not otherwise specified or categorized, that still meet the overarching requirements of the heading. This ensures comprehensive coverage for all applicable products.
