Other Preserved or Cooked Crustaceans (Dried, Salted, Brined, Smoked, or Boiled in Shell)

Species such as mantis shrimp (stomatopods), barnacles, crayfish, and various regional crustaceans that lack a dedicated HS heading are commonly classified here. The key is that the product must not fit the more specific headings for rock lobster (030691), Homarus lobster (030692), crab (030693), or shrimp/prawns (030695). When in doubt, a binding ruling request to CBP can resolve ambiguous species classifications.

Yes. Crustaceans that are steamed or boiled in shell are specifically captured under this heading (030699) even if they are subsequently frozen or chilled, distinguishing them from raw frozen crustaceans classified elsewhere in Chapter 3. The cooking step is the determining factor, and importers should ensure that processing records clearly document whether the product was cooked prior to freezing.
