Origin processing plant, exporter/Seller's process

a) Origin processing plant

  • Approach USDA to request authorization.

  • If a processing, handling or storage plant located in the USA is interested in exporting to Mexico, it is necessary for that plant to be approved and authorized by the sanitary authority in the USA.

  • Seek the authorization/granting of the plant stamp issued by USDA.

  • To be current with its tax registration, return and payment before the US Government –having a TAX ID or Tax ID Number.


b) Plant Inspection Stamps

  • Once USDA inspects the facilities and processes of plants which wish to be authorized for processing, handling and/or storing eggs, they will be provided an authorization number and a rubber stamp which shall be stamped on boxes and/or packages of products exported to Mexico. 

  • Packages and cases of goods shall be marked/labeled with USDA’s inspected stamp and with the establishment number (for example: PLANT-42), which is allocated to the plant where the product is produced/processed and it is the number identifying the plant.

  • The establishment number may appear on the package inside USDA’s inspected stamp as shown in the picture. It may also appear anywhere outside the package or on the package label, as long as it is present in a prominent manner, on all goods and/or cases in a legible manner and of the appropriate size ensuring good visibility and easy recognition.

c) Exporter/Seller’s Process


i. Look for a Plant Approved by USDA

Look for a processing, handling or storage plant authorized by the USDA and which is near your farm, and reach an agreement for the shipping and receiving the goods that are to be exported. 


ii. Contract a Freight Forwarder

The Freight Forwarder will manage the logistics between the client contracting him and the services involved in the transportation of goods to the destination Country.

When looking for a Freight Forwarder, it is important to evaluate the following –since on this depends, to a great extent, the speed and agility with which goods will cross to the destination Country:

  • Does he have the capacity to handle my product?

  • Does he know how to handle my product?

  • How large is his suppliers and collaborators network?

  • How is the level of communication?

  • What is his experience handling my product?
