On May 22, 2026, the Agency for Digital Transformation and Telecommunications (“ATDT”) held the webinar titled “Single Window for Foreign Trade Procedures”, with the purpose of presenting the operation of the new Single Window and addressing questions related to its implementation.
The most relevant points are summarized below:
1. Launch of the new Single Window
The new Single Window will be enabled as of May 25, 2026. During the initial stage, access will continue through VUCEM in order to avoid operational confusion; however, VUCEM is expected to gradually disappear as the implementation of the new platform progresses.
2. Platform access
Access will initially be granted through the e.firma Subsequently, the use of the Legal Entity Digital Key is expected to be implemented as part of the digitalization and simplification process for foreign trade procedures.
3. Procedures available during the initial stage
At the beginning, the Single Window will include procedures related to the Ministry of Economy, the Tax Administration Service and the National Customs Agency of Mexico. Other federal authorities may be incorporated at a later stage as the implementation process advances.
4. Administration of the Single Window
The ATDT will be responsible for administering the Single Window, monitoring its operation and supervising response times. However, the reception, analysis, review and resolution of procedures will remain under the authority of each competent agency, in accordance with their legal powers.
5. Update calendar
The Single Window will include a monthly update calendar, through which users will be informed of the functionalities that will gradually become available. In the event of any substantial change, it is expected that such change will be communicated in advance and accompanied by user training.
6. Single foreign trade file
The gradual creation of a single foreign trade file is expected, which will include corporate, tax and administrative documentation previously uploaded and validated. This will allow the Single Window, in subsequent procedures, to request only the user’s authorization to consult such documents.
7. Monitoring system and traffic light mechanism
The Single Window will incorporate a monitoring system to track response times and requests for additional information issued by the authorities. The traffic light mechanism will make it possible to identify the status of procedures and generate alerts when there are delays or potential deviations from the applicable legal framework.
8. Requests for additional information
One of the objectives of the new platform is to prevent authorities from requesting documentation or requirements that lack a legal basis. If a request for additional information falls outside the applicable legal framework, the ATDT may issue alerts to the corresponding agency.
9. Assistance mechanisms
As of June, a chat assistance tool is expected to be enabled to report issues related to the Single Window. It was also indicated that specialized assistance may be provided through the 079 line.
10. Nature of notices
It was clarified that, by their nature, notices should not be subject to a resolution by the authority, since they constitute an obligation of the regulated party to inform the authority of a specific activity. However, this does not eliminate the authorities’ verification powers regarding the information and documentation submitted.
The implementation of the new Single Window represents a significant change in the digital management of foreign trade procedures in Mexico. Although operations will initially continue through VUCEM, the objective is to move toward a centralized platform with greater interoperability among authorities, fewer requirements and improved traceability of procedures.
From an operational perspective, companies should pay particular attention to platform access, corporate and tax documentation, procedure follow-up, responses to requests for additional information, and documentary evidence related to any issue that may arise during the transition period.
Recommendation
Importers, exporters and companies that use foreign trade programs or procedures are advised to timely review the validity of their e.firma, keep their corporate and tax documentation up to date, monitor updates to the new Single Window and document any incident, request for additional information or delay that may arise during its implementation.
