Arrival at the border

         a) Transfer and/or Reloading

Transfer or reloading of goods usually is done on the US border side and before crossing the border. To this end, a Mexican carrier has to enter the US with his truck. Usually this maneuver takes place in an authorized warehouse or cold storage, and it consists of shifting /mounting the refrigerated container carrying the goods from the US truck onto the Mexican truck. The objective is for the Mexican truck with the refrigerated container to cross the border, enter Mexico and transit in the Mexican territory without any inconvenience. This is because there is a special permit required for US truckers by the Mexican Government to drive on Mexican highways. This is done with most of the shipping companies since it is more practical for them.


It is recommended that in the warehouse or hatchery a review or inspection of the merchandise by the custom broker or customs agent can be carried out before the merchandise crosses the border to corroborate that the merchandise is physically and documentary correct.


If any US shipping company is interested in getting a permit before the Mexican Ministry of Communications and Transportation to enter with its trucks into Mexico and deliver the goods in the final destination, the following link may be reviewed: preventiva/autotransporte-federal/temas-internacionales/autotransporte-transfronterizo-mexico- estados-unidos/



b) Entry into the Bonded Warehouse

Due to the sensitive nature of the goods, inspection, handling and agile and delicate transport are required at all stages


i. When the customs review is carried out before the OISA’s inspection

The trucker of the shipping company shall find the signage at the entry, and go to one of the modules according to the automated system for importation at customs, and give the person in charge of the module the pedimento for the goods in question. Then, he shall follow the fiscal route and pull over in one of the customs review platforms if the result at the module is Customs Review (Red Traffic Light). Otherwise he goes to the exit/completed module to exit the bonded warehouse towards the external verification site that has been hired to perform inspection of goods by the animal health authority (SENASICA).


ii. When OISA’s inspection takes place before the customs review

The trucker shall find the signage at the entry and show that he has an appointment with the Customs Broker at the Sanitary Verification and Inspection Point (PVIZ). Then, he will go to the bonded warehouse where the internal PVIZ is located, which has been hired to carry out the inspection of goods by the animal health authority (SENASICA). He shall pull over in the platform he is indicated, and wait for the inspection to take place. Once, the inspection is finished, he shall wait for the instructions by the Customs Broker, so he is given the pedimento covering the goods and so he can follow the fiscal route to go to the automatic-selection modules of importation at customs and to follow the steps indicated in paragraph 1 until he leaves the exit/completed module.


c) Beginning of Inspection by SENASICA


i. Mexican Foreign Trade Digital Window


The single window (VDMCE) is intended to allow individuals, through an electronic one-stop shop, to carry out applications regarding importations, exportations and foreign trade transit of goods, in accordance to the steps stated in the Decree, and given the case, those defined by the corresponding Mexican authorities for foreign trade. Through the one-stop shop, documents are managed for the release of goods, and importation processes are authorized or stopped.

Use conditions:

On the 14th of January, 2011, the Decree creating VDMCE System was published in the Official Gazette of the Federation.

The VDMCE system will automatically generate four types of folio numbers, which SENASICA’s authorized inspectors will manage in the portal depending on the stage of the paperwork process:


For folio numbers with a 200 included, this refers to the entering procedure for document review. If this phase is met satisfactorily, it will trigger a Document Review Opinion letter. An example of a request folio number under document review would be: 1502200200320137033000004.


When the folio number contains a 500, this is a physical inspection request which triggers an Importation Certificate. An example of a physical inspection request would be: 1502200500120137002000113.

When the folio number contains a 600, this refers to a modification request. An example would be: 150220160012137002000001.

When the folio number contains a 700, this refers to a deferral request or renewal of a previously issued certificate. Example: 150220070012137002000001.

The folio number of a released importation certificate will be 17 digits in length. It is made up in the following way: 3 digits: Customs; 2 digits: OISA; 2 digits: inspection site; 4 digits: year; and consecutive 6 digits. Example: 23039102013002819.
