Hydrogenated Animal Fats and Oils (Not Further Prepared)

Hydrogenation, interesterification, reesterification, and elaidinization are the chemical modification processes that define this heading — transforming animal fats and oils into more stable, functional forms used in food manufacturing and industrial applications. The single US tariff line (1516100000) captures all such animal-derived products regardless of refinement level, provided they are not further prepared beyond these processes. Norway leads US import supply, followed by China and Germany, reflecting both the marine-oil processing industry in Scandinavia and the broad oleochemical manufacturing base in Asia and Europe. Importers should confirm FDA admissibility status when the product is destined for food use, as labeling and composition requirements apply.
