0303.67.00.00 - Alaska pollock (Theragra chalcogramma)

This classification pertains to frozen Alaska pollock (Theragra chalcogramma). Alaska pollock is a species of cod-like fish belonging to the family Gadidae, which is explicitly included in the broader parent category. These fish are typically caught in the North Pacific Ocean and are a significant source of white fish for various food industries. The "frozen" aspect is crucial, distinguishing these from fresh or chilled fish covered elsewhere in Chapter 3.

Within the broader group of frozen fish from families like Gadidae, this specific heading isolates Alaska pollock. It is important to differentiate this from other members of the Gadidae family such as cod (0303.63.00), haddock (0303.64.00.00), coalfish (0303.65.00.00), hake (0303.66.00.00), and blue whitings (0303.68.00.00). While all are frozen fish from closely related families, their distinct scientific and common names form the basis of their separate classification. This category focuses exclusively on the species *Theragra chalcogramma*.

As this is a leaf node in the HTS classification system, there are no further subcategories under 0303.67.00.00. Therefore, any frozen Alaska pollock that meets the general requirements of heading 0303 and the specific familial and refrigeration criteria of the parent subheading will be classified here. This means that variations in processing, such as fillets or other fish meat of heading 0304, would be excluded and classified elsewhere.
