Frozen Prepared or Preserved Vegetables (NES) and Vegetable Mixtures

Classification of mixed or NES frozen vegetable products requires evaluating whether any single vegetable component constitutes the essential character of the product and whether that vegetable has its own dedicated heading. If no single vegetable dominates or if the product is a true blend, the NES or mixture classification typically applies. A binding ruling request to US Customs and Border Protection can provide certainty for recurring shipments of complex blends.

FDA frequently flags frozen vegetable mixtures for pesticide residue levels, undeclared allergens in seasoning packets included in the package, and labeling deficiencies such as missing country-of-origin information for multi-origin blends. Importers should request pesticide residue certificates of analysis from suppliers and ensure that all added ingredients — including sauces, seasonings, and coatings — are fully disclosed on both the label and the commercial invoice.
