1605.40 - Other crustaceans:

HTS code 1605.40 encompasses "Other crustaceans," a broad category within the chapter dedicated to preparations of aquatic invertebrates. This classification is intended for crustaceans that do not fall into the more specific subheadings for crab (1605.10), shrimp and prawns, lobster (1605.30), molluscs, or other aquatic invertebrates. The key criterion for classification under 1605.40 is that the product must be a preparation of a crustacean, meaning it has undergone some form of processing beyond simple preservation, such as cooking, seasoning, or inclusion in a mixture.

Unlike the preceding sibling categories which specifically identify common types of crustaceans like crab and lobster, or general groupings like molluscs, 1605.40 acts as a residual category for all other prepared or preserved crustaceans. This would include items like prepared crayfish, barnacles, or other less commonly traded crustacean species that have been processed for consumption or further use. The distinction relies on identifying the primary crustacean ingredient and ensuring it is not specifically accounted for in the more narrowly defined subheadings.

The subcategories under 1605.40 further refine the classification based on the nature of the preparation. 1605.40.05.00 is designated for products that specifically contain fish meat in addition to the other crustaceans or are presented as prepared meals. This distinction is crucial as it separates composite products where fish is a significant component or ready-to-eat meals from simpler preparations of crustaceans. The residual subheading, 1605.40.10, covers all other preparations of other crustaceans not falling under the more specific subcategory, ensuring comprehensive coverage for this diverse group of aquatic invertebrate preparations.
