0302.56 - Blue whitings (Micromesistius poutassou, Micromesistius australis):

This HTS category, 0302.56, specifically classifies blue whitings, scientifically identified as *Micromesistius poutassou* and *Micromesistius australis*. These are distinct species within the broader family of Gadidae, which are characterized by their three dorsal fins and two anal fins. The classification applies to these fish when they are presented fresh or chilled, excluding processed forms like fillets or other fish meat covered under heading 0304.

Distinguishing blue whitings from their siblings at this level, this subheading focuses solely on these two specific species. For instance, while 0302.51.00 covers cod and 0302.53.00.00 covers coalfish, this entry is exclusively for blue whiting, ensuring precise tariff application based on species identification. The parent category, covering fish from specific families like Gadidae, provides the overarching context for these various species classifications.

The subcategories under 0302.56 further refine the classification based on the condition and presentation of the blue whiting. Subheading 0302.56.11.00 details scaled blue whitings, which may have heads, viscera, and/or fins removed but must not be otherwise processed, and are presented in smaller immediate containers. Subheading 0302.56.50.00 serves as a residual category for all other fresh or chilled blue whitings that do not meet the specific criteria of the preceding subheading, ensuring comprehensive coverage within this classification.
