0511.91.00 - Products of fish or crustaceans, molluscs or other aquatic invertebrates; dead animals of chapter 3

This HTS subheading, 0511.91, encompasses dead animals, or products thereof, originating from fish, crustaceans, molluscs, and other aquatic invertebrates. It specifically includes these aquatic life forms that are not intended for human consumption. The scope covers a wide range of aquatic animal products, such as inedible fish parts, processing waste from seafood, or entire dead aquatic animals that have not undergone processing or preparation suitable for food.

Within the broader category of "Other" products of animal origin not elsewhere specified or included (Chapter 05), this subheading differentiates itself from its sibling, 0511.99, which covers other dead animals of Chapter 1 or Chapter 3 not otherwise specified. While 0511.99 is a broader residual for other dead animal categories, 0511.91 is specifically dedicated to aquatic life.

To provide further clarity, the subheading 0511.91 is further divided into subcategories to capture specific uses or forms. Subheading 0511.91.00.10 is reserved for fertilized fish eggs, often used in aquaculture or scientific research. The residual subheading, 0511.91.00.90, captures all other products and dead aquatic invertebrates not specifically enumerated, ensuring comprehensive coverage for items within this scope.
