0306.19.01 - Other

This HTS category, 0306.19.01, encompasses frozen crustaceans that do not fit into the more specific sibling categories under the broader heading of frozen crustaceans. It serves as a residual classification for items not explicitly listed elsewhere at this level, such as certain types of frozen shrimp, prawns, or other shellfish not specifically named, provided they meet the general criteria for frozen crustaceans.

Distinguishing this category from its siblings is crucial for accurate classification. For instance, it does not include frozen rock lobster and other sea crawfish (0306.11.00), frozen lobsters (0306.12.00), frozen crabs (0306.14), frozen Norway lobsters (0306.15.00.00), or frozen cold-water shrimps and prawns (0306.16.00). If a frozen crustacean product is specifically enumerated in one of these sibling codes, it must be classified there, rather than under this "Other" designation.

Within 0306.19.01, further subdivisions exist to capture specific types of these residual frozen crustaceans. These include classifications for freshwater crawfish (0306.19.01.10), Antarctic krill (Euphausia superba) (0306.19.01.30), and a final residual category for "Other" (0306.19.01.61) which acts as a further catch-all for any remaining frozen crustacean products not falling into the more specific sub-classifications.
