Last updated: April 2026 dataBody-derived fish oils — including menhaden, anchovy, sardine, and herring oils — are among the most widely traded marine lipids, serving as omega-3 concentrate feedstocks for dietary supplements, aquaculture feed, and oleochemical processing. Unlike fish liver oils, these products are extracted from the whole fish body and carry a distinct fatty-acid profile dominated by EPA and DHA. FDA oversight applies to edible and supplement grades, and importers should be aware that some marine oil supply chains intersect with CITES-listed species, requiring documentation of legal harvest origin.
AI-written summary of the official U.S. Census Bureau trade figures on this page — verify before relying on it.
Yes — if the source species is listed under CITES appendices (for example, certain shark species), the oil may require CITES export documentation from the country of origin and a US Fish and Wildlife Service import permit. Importers should verify the species of origin and its CITES status before shipment.
Crude fish oil undergoes minimal treatment (pressing and centrifugation), while refined oil has been degummed, bleached, and deodorized. Concentrated fractions — such as ethyl ester or triglyceride-form omega-3 concentrates — may move to pharmaceutical or chemical headings depending on concentration and intended use. The degree of processing and end-use application are the key classification determinants.
