Mexico - Updated Advisory

Updated Requirements on ATA Carnet Procedures

May 6, 2026

We just received notification from the United States Council for International Business (USCIB) regarding Mexico updates on ATA Carnet Procedures: Mandatory Pre-Registration, Fees and Penalty

Mexico has introduced new requirements for ATA Carnet holders that significantly impact how Carnets must be used when entering and exiting the country. These updates are now mandatory and should be carefully followed to avoid delays or penalties.
 

New Requirement: Pre-Register Your ATA Carnet 7+ Days Before Arrival

ATA Carnet holders traveling to Mexico must notify Mexican Customs at least 7 days in advance of their intended visit.

For direct technical support and guidance with pre-registration, contact:comint1@ccmexico.com.mx

Entry Requirement Steps (New):

After completing registration:

  • A registration folio will be generated and should be printed immediately
  • This folio must be presented to Mexican Customs upon entry along with the ATA Carnet

Payment must be made and proof of payment must be sent to CANACO

Exit Requirement Steps (New):

When leaving Mexico, holders must:

  • Notify departure using the registration folio number
  • Upload scanned ATA Carnet pages with all corresponding stamps (entry stamps to Mexico and return to origin)

Email required materials to CANACO within 1 week of leaving Mexico.

Existing Rules below are still in effect

While the above procedures are new, the following requirements remain unchanged:

Temporary Admission Period

  • Goods must be re-exported within 6 months

Extensions

  • A one-time extension (up to 6 additional months) may be granted
  • Must be requested at least 2 months before the initial 6-month deadline
  • If the Carnet expired, a replacement Carnet must be issued solely for the re-exportation
  • Subject to Mexican Customs approval
  • Extension details: https://carnet-ata.org/nuestros-servicios/prorrogas/
  • Contact: negint@ccmexico.com.mx

Penalties for Late Re-Export

Failure to re-export goods on time may result in fines:

  • Between $2,670 and $4,030 MXN
  • Applied every 15 days (or fraction thereof) after the deadline
  • Total penalties will not exceed the value of the goods
  • To avoid penalties, request an extension in advance through CANACO.


Note special considerations for Carnets going to Mexico:

  • At this time, all Customs ports in Mexico validate ATA Carnets in and out of Mexico.

  • The General List is no longer recommended to be translated into Spanish but it can be provided by boomerang carnets® if desired.
     
  • Note and track the Final Date of Re-Exportation on the white importation counterfoil as that is the final day the goods may be in Mexico. Regardless of whether Mexican Customs completes the Final Date of Re-Exportation, items can only be in Mexico for 6 months.
