Last updated: August 2026 dataCorn flour — finely milled from whole maize kernels — is a staple ingredient in tortilla production, gluten-free baking, and snack food manufacturing, distinguishing it from coarser corn meal or masa harina by its particle size and processing method. FDA food-safety requirements apply to imported corn flour, including prior notice and potential port-of-entry examination. Importers sourcing corn flour should verify whether the product is derived from conventional, non-GMO, or organic maize, as these distinctions affect labeling obligations and buyer specifications in the US market.

Corn flour is more finely ground than corn meal and is classified under a different SITC heading than groats and meal.

Importers should provide particle-size data and processing descriptions to support accurate classification.
Yes — the USDA National Bioengineered Food Disclosure Standard (NBFDS) requires disclosure of bioengineered ingredients in food products sold in the US.
