Last updated: April 2026 dataCommodity corn — unmilled, non-seed, non-sweet-corn maize — is one of the most widely traded bulk grains globally and serves as a primary feedstock for ethanol production, wet and dry milling, and livestock feed formulation in the United States. The US is itself a dominant exporter, so import volumes tend to be regionally concentrated and driven by specific quality or logistical needs rather than broad supply gaps. Aflatoxin and mycotoxin testing is a standard FDA admissibility concern for imported corn, and shipments must comply with FDA prior-notice requirements.
AI-written summary of the official U.S. Census Bureau trade figures on this page — verify before relying on it.
Import volumes are typically driven by regional logistics — for example, proximity to a specific port or processing facility — or by short-term domestic supply disruptions following drought or crop failure. Specialty non-GMO or identity-preserved corn varieties may also be sourced internationally when domestic supply is insufficient to meet processor specifications.
FDA enforces action levels for aflatoxin in corn intended for human food and animal feed. Importers should request aflatoxin and fumonisin test results from accredited laboratories at origin, as shipments exceeding FDA action levels are subject to refusal of admission. Consult a licensed customs broker or FDA-registered agent for current admissibility requirements.
