Last updated: April 2026 dataFish-liver oils — most notably cod liver oil — are widely used as dietary supplements and pharmaceutical-grade omega-3 sources, and the US tariff schedule separates cod liver oil (1504102000) from other fish-liver oils (1504104000), with a residual line (1504100000) for unspecified fractions. Norway and Iceland are the dominant suppliers, reflecting the North Atlantic cod and other demersal fisheries that underpin commercial liver-oil production. FDA regulates fish-liver oils intended for human consumption as food or dietary supplements, and importers must ensure labeling and facility registration comply with applicable requirements. Classification and admissibility are complex — consult a licensed customs broker or FDA for guidance specific to your product.
