Preparation of shipment and/or Load

a)   Packaging  

  • Primary Packaging: It is the container aimed at containing a product and which is in contact with it.

  • Secondary Packaging: It is the container used to contain primary packaging.

  • Packaging Materials: They are all the materials, procedures and methods used to condition, present, handle, store, preserve and transport goods.

Eggs shall comply with the applicable standards, laws and regulations –which define the criteria for quality, weight, freshness, packaging and labeling– to be marketed and exported/imported.


Eggs are packaged after they have been classified and graded. External packaging materials of eggs shall be new, shock-resistant, dry, clean and in good condition. Usually, these materials protect eggs from off-odors and of possible quality alterations –moderate pulp, cardboard or polyethylene.

All corrugated fiber filler floors used for packaging and packaging material must be new, showing no evidence of prior use. Any unmanufactured wood materials used to stabilize the eggs on pallets must be new or independently certified to meet the International Phytosanitary Standard (ISPM-15).


Shipping containers must be sealed (company seal) prior to departure from the processing facility. Stamp numbers must appear on the Form, LPS-210S.


Eggs should be sold to consumers during the 21 days after it was laid, even though they can be consumed until the best-by date on the package, which is by the 28th day after they were laid.


i. Bulk and Wholesale


Eggs intended to be sold bulk or wholesale are placed in polyethylene, cardboard or molded pulp cartons, boxes or trays where they can be transported without moving. Eggs are commonly contained in packages of 24 or 30 pieces according to the label placed on the outside he supplier. These are in turn packaged in cardboard boxes which protect against shocks. Boxes are sealed, adhesive tape is used and a fully identifying information label is placed on the outside. Box resistance should be capable of withstanding the stacking height without deformations. The net weight of the box will be classified with the number of individual eggs per box.

Example: 30 dozen boxes = 360 eggs per box or 15 dozen boxes = 180 eggs per box.











ii.- End-consumer and Retail

Eggs intended for retail are placed in plastic or cardboard cartons, boxes or trays that can hold eggs without movement. Eggs are commonly contained in packages of 6, 12 or 18 pieces according to the suppliers. They are also packaged in cardboard boxes which protect against shocks.

ii.- End-Consumer and Retail

It is important and necessary that if the products  are intended for sale to the final consumer (retail) you must go to an authorized verification unit to review and guarantee that your labeling is correct, the verification unit is the only competent entity to carry out said activity.

The Modification Labeling Standard NOM-051-SCFI/SSA1- Compliance with the labeling regulation is mandatory for all products marketed in Mexico. Beginning October 1st, 2020, all prepackaged non-alcoholic foods and beverages entering the country must comply with the modifications to the labeling regulation to be admitted at the point of entry.

At the point of entry, the importer will need to provide a Proof of Conformity (Dictamen de cumplimiento) to the customs agent. These documents can be emitted only by an accredited verification unit (before known as UVA) now Inspection Unit. The Proof of Conformity will require an on-site verification visit.

It is important to mention that compliance with the labeling regulations is not certifiable and accreditation by a verification unit is voluntary EXCEPT for importers, in which case the verification document is mandatory to allow the product in.

It is necessary that as of October 1st, 2020, the updated Proof of Conformity with NOM-051-SCFI/SSA1-2010, along with the other documents, be delivered to the customs broker at the time of export. It is possible to make a commitment letter so that the labels can be conditioned with adhesives under the supervision of a Verification Unit and thus import the product, if the compliance report was not available by October 1.

Imported products are allowed to use adhesives to comply with the labeling requirements indefinitely.

NOM-051-SCFI/SSA1-2010 labelling information may be translated from origin or made after the goods have been entered into national territory, after customs release, but before sale to the final consumer. So, it is recommended to hire a Verification Unit.


It is necessary that the information or labels affixed to Ready-to-Eat product packages have the information that the Mexican health authority requires in accordance with NOM-051-SCFI/SSA1-2010 Mexican Standard.

The suggestion is to place the label in the front or on one end of the box with the information below; it shall be clearly visible, and it shall allow for its full identification –the word eggs and the brand name shall be the same size.

Spanish language label with the following information:

  • Name or common denomination of product.

  • Egg Grade (A, AA).

  • Brand.

  • Importer/responsible for the product name and address.

  • Manufacturer’s data.

  • List of ingredients in descending order (for ingredients 5% and up in the composition, water, colorants, additives, etc.).

  • Use or cooking instructions.

  • Contents, net weight and drained mass (as the case may be).

  • Production or laying date.

  • Expiration date.

  • Country of origin using the legend: “hecho en” (“made in”) or “producto originario de” (“product from”).

  • Legend: "manténgase en refrigeración" (“keep refrigerated”) or "consérvese en congelación" (“keep frozen”) and “manténgase a - grados° C” (“keep at - ° C”) as the case may be.

  • Lot or corresponding lot number(s).


Information on labels shall match the information on the export health certificate and the provisions of article 89 of the Federal Animal Health Law that apply in accordance with the corresponding HRZ.

Nutrition labelling declaration is mandatory on the label of prepackaged products, and is separate from the specifications of the nutrimental frontal labeling (Data shown are not real, is just an example).

Front Labeling System


  • 5 potential seals are to be included when the regulation’s profiles are exceeded. The seals size, grouping, order, and location, varies depending on the product presentation. There are seals with numbers instead of with legends (excess calories, sugars, saturated fats, trans fats, sodium) for labels smaller than 40 cm2. The specific text content, proportions and formatting of the seals are specified in the standard.

  • If your product contains caffeine and/or sweeteners, the warning legends must be displayed in the right location and proportion.
