Foreign facilities producing breakfast cereals for US import must register with FDA under the Food Safety Modernization Act and comply with the Foreign Supplier Verification Program requirements. Each shipment requires prior notice submission to FDA before arrival, and products must carry English-language labeling with a compliant Nutrition Facts panel and ingredient list.

The HTS classifies prepared cereal foods primarily by the grain used — corn, oats, wheat, rice, or mixed grains — and by whether the product is puffed, flaked, or otherwise processed. Importers should ensure the commercial invoice specifies the grain composition and processing method, as misclassification between subheadings can result in duty underpayment and potential penalties.
