Last updated: August 2026 dataCod liver oil and other fish liver oils — valued for their high concentrations of vitamins A and D as well as omega-3 fatty acids — are traded both as dietary supplement ingredients and as industrial inputs for pharmaceuticals and animal feed. FDA regulates edible and supplement-grade fish liver oils as food or dietary supplement ingredients, requiring compliance with labeling, purity, and Good Manufacturing Practice standards. Fractions of fish liver oil (such as squalene-enriched or vitamin-concentrated fractions) may face additional scrutiny depending on their intended use and concentration levels.

Fractions — produced by physical separation such as winterization or molecular distillation — remain within this heading as long as they are derived from fish liver oil. However, if a fraction is further chemically modified or concentrated to pharmaceutical-grade standards, it may shift to a different HTS chapter covering pharmaceutical preparations. A customs broker should review the degree of processing and intended use.
Fish liver oil sold or used as a dietary supplement ingredient must comply with FDA's Dietary Supplement Health and Education Act (DSHEA) framework, including identity, purity, and strength specifications. Bulk ingredient importers should also ensure the foreign supplier holds documentation consistent with FDA's Current Good Manufacturing Practice (cGMP) regulations for dietary supplements.
