Sub-classifications

Commodity Code
Description

Overview

This HTS category, 0309.90.10, specifically encompasses frozen flours, meals, and pellets derived from fish, crustaceans, molluscs, and other aquatic invertebrates that are fit for human consumption. The defining characteristic of this classification is the frozen state of the product, which preserves it for a longer shelf life and often facilitates its use in various food processing applications.

It is crucial to distinguish this category from its siblings. HTS code 0309.90.20.00 covers the same types of aquatic invertebrates but only when they are live, fresh, or chilled. This distinction is based solely on the temperature and state of preservation of the product at the time of import or export.

Within this "Frozen" category, further subdivisions exist to provide more granular classification. Subcategories such as 0309.90.10.10 for freshwater crawfish, 0309.90.10.30 for Antarctic krill, and 0309.90.10.61 for "Other" frozen aquatic invertebrate products allow for precise identification based on the specific type of invertebrate. These subcategories enable trade professionals to accurately report the specific commodity being traded, which can be important for trade statistics, regulatory compliance, and duty calculation.
