Products classified under HTS 1504.10.40.00
Cod Liver Oil
Cod liver oil is extracted from the livers of Atlantic cod (Gadus morhua) and is a rich source of omega-3 fatty acids like EPA and DHA, as well as vitamins A and D. It falls under HTS 1504.10.40.00 as a fish-liver oil that is refined but not chemically modified, distinct from other fish oils. This subheading covers 'other' fish-liver oils beyond specific types like those from halibut.
Pollock Liver Oil
Pollock liver oil, derived from the livers of Alaska pollock (Gadus chalcogrammus), is refined for use in supplements providing omega-3s and fat-soluble vitamins. Classified under HTS 1504.10.40.00 as 'other' fish-liver oils not chemically modified. It is not from listed specific species, fitting the residual category.
Hake Liver Oil
Refined hake liver oil comes from the livers of hake fish (Merluccius species) and is used in nutritional supplements for its high vitamin content. It qualifies for HTS 1504.10.40.00 as an 'other' fish-liver oil fraction, refined but chemically unmodified. Distinct from body oils or chemically treated products.
