Last updated: April 2026 dataRefined corn oil — a staple cooking and frying oil in foodservice and retail — is split at the 10-digit level between once-refined (1515290020) and fully refined (1515290040) product, a distinction that matters for both duty treatment and end-use specifications such as smoke point and color. Canada and Mexico are the leading US suppliers, benefiting from proximity and USMCA trade terms. Importers of food-grade refined corn oil must comply with FDA admissibility requirements, including prior notice of food shipments.
AI-written summary of the official U.S. Census Bureau trade figures on this page — verify before relying on it.
Once-refined corn oil (1515290020) has undergone partial processing — typically degumming and neutralization — but retains some color and odor. Fully refined corn oil (1515290040) has been bleached and deodorized to meet food-grade specifications. The degree of refining must be documented by the exporter, as misclassification between these two lines can result in duty discrepancies and CBP examination.
Importers should check with CBP and the USITC for any active antidumping or countervailing duty orders covering refined corn oil from specific countries. No broad Section 301 measures currently target corn oil as a standalone commodity, but origin-specific exposure can arise. A licensed customs broker can run a current scope check before committing to a supply source.
