1605.40.10.90 - Other

This classification covers prepared or preserved crustaceans that do not fall into more specific subheadings within heading 1605.40. This includes various forms of processed crustaceans, such as those that are cooked, canned, frozen, or dried, which have undergone preparation beyond simple cleaning or freezing. The key characteristic is that they are preserved in a manner that extends shelf life and ready for consumption or further processing.

Distinguishing this "Other" category from its sibling, 1605.40.10.10, is crucial. The sibling specifically addresses "Peeled freshwater crawfish tail meat," indicating a very precise product. Therefore, this "Other" category encompasses all other prepared or preserved crustaceans, including those that are not freshwater crawfish, are not peeled, or are not solely tail meat. Examples could include whole preserved shrimp, crab meat (not specifically defined elsewhere), lobster segments, or other aquatic crustaceans in various preserved states.

As this is a leaf node, there are no further subcategories to introduce. Classification within this subheading relies on the exclusion of more specifically enumerated items within the broader heading of prepared or preserved crustaceans. Therefore, careful consideration of the product's exact form, species, and preparation method is essential to ensure it is correctly classified under this residual "Other" provision when it does not meet the criteria for any more granular HTS code.
