    Overview of Mexico’s Front-of-Pack (Phase 1) and Nutrition Labeling Regulation Updates

    Updated nutrition labeling regulations for Mexico became final on March 27, 2020, and will be rolled out in three implementation phases. To assist with compliance, ESHA has incorporated these regulations into the last version of Genesis R&D Foods. Learn more.

    Overview of the Regulations

    At the beginning of Phase 1, manufacturers must include the new front-of-package (FOP) warning symbols and statements on all product packaging (some exemptions apply). Again, because of the small implementation window, the symbols can be affixed to the package as stickers until April 1, 2021. From Oct. 1, 2020, through March 31, 2021, packages may show existing Nutrition Facts and FOP guidelines as long as they also include the new FOP warning symbols and statements.

    After April 1, 2021, the changes to the Nutrition Facts, ingredient statement, allergen statements, and the FOP symbols and statements must be implemented on all packaging.

    Phase 1 includes:

    • Updated FOP warning seals and statements (replacing current icons)
    • Added Sugars grouped by weight in the Ingredient Statement
    • Updated list of allergens
    • Added Sugars and Trans Fat as a mandatory label nutrients
    • Modified declarations requirements for voluntary nutrients
    • Changes to the label format

    Implementation Dates

    • Phase 1 — Oct. 1, 2020* – Sept. 30, 2023
    • Phase 2 — Oct. 1, 2023 – Sept. 30, 2025
    • Phase 3 — On and after Oct. 1, 2025

    *Note: Due to the short implementation timeline for manufacturers to use existing inventory, the enforcement date has been delayed to Nov. 30, 2020.

    FOP Warning seals

    New warning seals and statements will replace the current FOP icons. Manufacturers will have to determine which of these nutrients [Energy (kcal), Sugars, Saturated Fats, Trans Fats, Sodium] exceed the recommended intake thresholds. This is a new requirement. All seals that apply should be listed on the package, and small packages can use a number to signify how many seals apply.

    The original FOP (front-of-package) icons were designed to inform consumers of the amounts of selected nutrients and proximates. In contrast, the new FOP icons warn consumers when the amounts exceed intake recommendations for Calories, Total Sugar, Saturated Fat, Trans Fat, and/or Sodium.

    The warning symbols look like this:

    These are the octagon-shaped warning symbols used on food packages in Mexico to warn consumers when certain nutrients exceed recommended thresholds.

    and must comply with the following layout specs:

    • Shape: Regular octagon
    • Background color: Black with white outline
    • Font: Arial Bold in white, to contrast with the background.
    • Placement: Primary Display Panel (almost always the front)

    Warning Statements

    The packaging design changes also call for warning statements when the product contains “non-nutritive” sweeteners and caffeine.

    • Products that contain caffeine must include the warning “CONTIENE CAFEÍNA — EVITAR EN NIÑOS” (“Contains caffeine — children should avoid”).
    • Products that contain sweeteners must include the warning “CONTIENE EDULCORANTES — NO RECOMENDABLE EN NIÑOS” (“Contains sweeteners — not recommended for children”).

    Label Layout

    The label header says Declaracion Nutrimental (Nutritional Declaration), which is a change from the previous Informacion Nutrimental (Nutritional Information), and reporting calories per package is now required for all labels.

    Two nutrients are now mandatory: Grasas trans (Trans fat) and Azucares añadidos (Added Sugars). They must be displayed on the label in bold, along with existing mandatory nutrients: Contenido energético (Calories), Grasas saturadas (Saturated Fat), and Sodio (Sodium).

    Other label layout specifications (font size and rule width) remain consistent with the previous version.

    Nutrient Changes


    Azucares añadidos (Added Sugars) are defined as “Sugars added during the industrial process” and differentiated from Azucares (Free Sugars), which are defined as “available mono and disaccharides added to the product plus naturally occurring sugars in honey, fruit, vegetables.” Both are mandatory on the label, Azucares añadidos newly so.

    Sugars, however, also differ from Sweeteners, which, again, appear on the front of the package. Those are defined as “Generally non-nutritive sweeteners, substances different from mono and disaccharides that provide sweet flavor to products.”

    Trans fat

    Trans fat now a mandatory label nutrient and is reported in milligrams instead of grams.

    Voluntary Nutrients

    Some nutrients have changed units. They are:

    Vitamin B1 mg µg
    Vitamin B2 mg µg
    Vitamin B6 mg µg
    Copper mg µg

    Ingredient statements

    Ingredients listed in descending order of predominance by weight and composite ingredients must disclose sub-ingredients in parenthesis when they represent more than 5% of the product.

    When Added Sugars are used in the product, the ingredient statement must group them together and display “Added sugars” followed by a list of the specific names, listed by weight, in parenthesis.


    If the product contains any of these allergens, they must be listed after the ingredient statement in bold font:

    • Gluten
    • Crustaceans and products
    • Eggs and byproducts
    • Fish and byproducts
    • Milk/dairy
    • Soy and byproducts
    • Tree nuts and peanuts
    • Sulfites
    • Molluscs (newly added allergen)

    Tree nuts must be listed by specific type. Example: Almonds, walnuts, hazelnuts, pecans, etc.

    When contamination is possible during production, the label must use a “may contain” statement.
