Last updated: July 2026 dataHydrogenation and interesterification chemically modify animal fats and oils — including tallow, lard, and fish oil fractions — to alter melting points and oxidative stability for use in food manufacturing, oleochemicals, and industrial lubricants. These processed fats occupy a distinct classification from their unmodified counterparts because the chemical transformation step, not the source animal, drives the tariff treatment. Importers should note that food-grade versions entering the US supply chain are subject to FDA oversight, while the industrial grades face fewer admissibility hurdles but may still require accurate country-of-origin documentation for duty purposes.

The chemical modification — whether hydrogenation, interesterification, esterification, or re-esterification — is the defining classification criterion. Fats that have undergone these processes fall under 43121 regardless of the source animal, while crude or simply rendered fats are classified elsewhere. Importers should confirm the degree of processing with the foreign supplier to avoid misclassification.
Yes. Food-grade animal fats intended for human consumption are subject to FDA oversight and may require prior notice filing under the Bioterrorism Act. If derived from meat or poultry processing, USDA FSIS jurisdiction may also apply. Consult a licensed customs broker or the relevant agency to confirm admissibility requirements for your specific product.
