Importers should provide a certificate of analysis specifying the modification process (e.g., hydrogenation, interesterification, oxidation), the degree of modification (e.g., iodine value, trans-fat content, peroxide value), and a declaration of inedibility if the product is not intended for food use. Without clear technical documentation, CBP may question whether the product belongs in the modified/industrial category or in a food-grade refined oil heading.

Products explicitly classified and documented as inedible industrial preparations generally fall outside FDA food jurisdiction, but importers must ensure that the inedible designation is substantiated by formulation and labeling. If there is any ambiguity about food versus non-food use, FDA may assert jurisdiction. Consult a licensed customs broker or regulatory counsel before importing to confirm the correct regulatory pathway.
