0306.19.01.10 - Freshwater crawfish

This classification pertains to frozen freshwater crawfish, also known as crayfish or crawdads. These are aquatic crustaceans, typically found in freshwater bodies, and are distinguished by their freshwater habitat as opposed to marine environments. The goods classified here are prepared in a frozen state for preservation and transport.

This specific code, 0306.19.01.10, is differentiated from its sibling entries by the nature of the crustacean and its preparation. It specifically excludes Antarctic krill (0306.19.01.30), which is a distinct species of small crustacean, and a general "Other" category (0306.19.01.61) which would encompass other types of frozen crustaceans not otherwise specified. Therefore, proper classification hinges on identifying the product as freshwater crawfish and confirming its frozen presentation.

As a leaf node, this category does not have further subdivisions. Classification at this level is definitive, meaning that if a product meets the criteria of being a frozen freshwater crawfish and is not specifically listed under another sibling code, it will be classified here. Examples include individually frozen crawfish, as well as frozen crawfish tails or other preparations that retain their freshwater crawfish identity.
