0303.68.00.00 - Blue whitings (Micromesistius poutassou, Micromesistius australis)

This HTS classification, 0303.68.00.00, specifically covers frozen blue whitings, which scientifically are identified as *Micromesistius poutassou* and *Micromesistius australis*. These fish are categorized under Chapter 3, which deals with fish and crustaceans, mollusks and other aquatic invertebrates. Within the broader scope of frozen fish from specific families, blue whitings are distinguished by their scientific classification and common names.

To differentiate this category from its siblings, it's important to note the specific species covered. For instance, while other codes within this section might classify cod, haddock, coalfish, hake, or Alaska pollock, this particular subheading is exclusively for blue whitings. The exclusion of fish fillets and other fish meat of heading 0304 is also a key point; this classification pertains to whole or sectioned frozen fish, not processed meat forms.

As 0303.68.00.00 is a leaf node within the HTS database, it does not have further subcategories. Therefore, classification under this code relies solely on the accurate identification of the fish as blue whitings (*Micromesistius poutassou* or *Micromesistius australis*) and that they are presented in a frozen state, aligning with the parent category's requirements.
