Sub-classifications

Commodity Code
Description

Overview

Heading 0303 encompasses a broad range of fish that have been frozen. This classification specifically excludes fish fillets and other fish meat that are categorized under heading 0304. The primary criterion for inclusion in 0303 is the frozen state of the fish, regardless of whether it is whole, headed, gutted, or in other forms, as long as it does not meet the definition of fillets or meat.

Distinguishing 0303 from its siblings at the Chapter 3 level is crucial. While other headings in Chapter 3 may cover live fish (e.g., 0301), fish, fresh or chilled (e.g., 0302), or fish fillets and other fish meat (0304), this heading is exclusively for fish that have undergone a freezing process. The "excluding" clause for 0304 is a key differentiator, directing processed fish meat to a separate category.

Within heading 0303, further subheadings (not fully detailed in the provided snippet but implied by the listed children) serve to classify frozen fish based on their species or family. This granular breakdown allows for more precise tariff application, considering the specific commercial and biological characteristics of different fish types. Subcategories exist to differentiate between important commercial species like salmonids and tunas, various types of flat fish, and staple food fish such as herrings and mackerels. Additionally, a distinct subheading is designated for edible fish offal, recognizing that parts of the fish other than the main flesh also have specific tariff treatments.
