The mandatory Electronic Declaration of Value (MVE) will be postponed once again. The Tax Administration Service (SAT) and the National Customs Agency of Mexico (ANAM) announced a further extension to the deadline for importers to comply with the mandatory electronic submission of this document. This decision represents the third extension granted by the authorities to one of the most important digitalization projects in foreign trade.

In a joint statement, both agencies announced that the requirement for the Electronic Mailing (MVE) will be extended until July 31, 2026 , to ensure that foreign trade users have the necessary tools to comply with this provision in a timely manner. This measure was established through the First Advance Version of the Second Resolution of Amendments to the General Rules of Foreign Trade for 2026, published on June 2nd on the SAT website.

The decision comes within the context of the digitalization strategy being promoted by the tax authority in coordination with ANAM, which seeks to migrate various foreign trade procedures to electronic platforms to strengthen information traceability, simplify processes, and improve customs control mechanisms. In the case of the MVE (Single Window for Foreign Trade), the scheme stipulates that information related to the customs value of goods be transmitted electronically through the “new” Single Window for Foreign Trade Procedures (VUTCE) before the goods are cleared.

According to the SAT (Mexican Tax Administration Service) and ANAM (National Association of Customs Agents), one of the main benefits of this mechanism is the mitigation of risks associated with errors in determining foreign trade duties. By submitting the information in advance and electronically, companies can reduce inconsistencies that could eventually lead to fines or penalties during customs audits.

In addition, the verifications carried out by the authorities are more efficient. The information submitted in advance allows for targeted inspections, reducing inspection times and, consequently, the time goods spend in customs. This is especially relevant for logistics operators and importing companies seeking to minimize costs associated with cargo release delays.

The economic component is also part of the arguments presented by the authorities. According to the statement, digitizing this process will reduce operating costs for both users and the agencies responsible for supervising and validating information related to import operations.

The Electronic Filing Mechanism (MVE) has been available for electronic submission since August 1, 2025; however, its mandatory implementation has faced several adjustments to the implementation schedule. With this new decision, the Tax Administration Service (SAT) and the National Association of Mexican Businesses (ANAM) are maintaining a gradual strategy for adopting the system, while continuing to support the business sector and implement technological adaptations to ensure compliance with the obligation.

With the announced expansion, the authorities reiterated their intention to facilitate compliance with foreign trade obligations through more agile, clear and accessible processes, while seeking to consolidate the digital transformation of customs procedures in Mexico.

El cargo Importers receive new relief in the Electronic Declaration of Value apareció primero en T21.

With the imminent entry into force of the Electronic Value Declaration (MVE) , a requirement that has generated uncertainty and operational pressure in foreign trade, the technology firm TGX, born from the logistics experience of Alser Logistics , developed a solution that seeks to resolve one of the main dilemmas of the sector: who should capture the information and under what conditions.

Héctor Alatorre, founding partner of TGX, explained in an interview that the MVE represents a structural change in the way companies must document their operations.

“It’s not like before, when it was filled out by hand. Now everything is electronic, and if there are discrepancies between the customs declaration, the COVE ( Electronic Value Certificate) , or the statement, the consequences can be serious, even the cancellation of the transaction,” he warned.

The challenge, however, is not solely technical. According to the executive, there is a tension between the authority’s position, which seeks to have the importer handle the process directly, and the operational reality, where customs brokers continue to concentrate the experience, information, and execution capacity.

“Importers don’t necessarily have the technology, knowledge, or personnel to do it. But they also don’t want to share sensitive information, such as their VUCEM (Mexican Single Window for Foreign Trade) seal. That’s where we found an opportunity,” he explained.

TGX’s solution is based on a model that integrates a third-party technology provider into its logistics ERP ecosystem . Through a separate portal, the importer can manage their MVE (Medium Value Entry) without relinquishing full control of their information, while the customs broker participates in data entry without having direct access to the digital seal.

This scheme allows the client to authorize in a granular way which agents can operate on their behalf, as well as validate or “sign” the final declaration before its submission.

“We solve the problem of IP, access to the seal, and trust. It’s a middle ground between what the authority requires and what the operation needs,” Alatorre stated.

In addition, the platform maintains a historical record of all generated demonstrations, which strengthens traceability and compliance.

From operation to technological development

TGX emerged as a natural extension of Alser Logistics, a company founded a decade ago and focused on door-to-door logistics solutions, mainly on the northern border of Mexico.

As the operation grew, integrating transportation, brokerage , and customs services , so did the need to develop its own technological tools.

“It all started from real-world operations. The system evolved with modules as we needed them: invoicing, transportation, accounting, tracking . That allowed us to build a robust ERP based on what the market really requires,” he explained.

Development of the MVE module began last December, driven by the imminent mandatory implementation of the measure. Within weeks, TGX launched a first functional version for its clients, adjusting it according to the challenges identified in the field.

Internal product or open solution?

Although the tool was initially conceived as a value-added service for its clients, TGX is considering making it available to the market as a standalone product. This would allow importers and customs brokers to use the platform without needing to subscribe to the full ERP system.

“We realized that it can be a product in itself. We are exploring releasing it as an affordable solution for more companies,” he commented.

Looking ahead, TGX plans to integrate artificial intelligence into its processes, particularly in areas such as quoting, tracking, and customer service. However, Alatorre emphasized that automation will not replace human judgment.

“Artificial intelligence helps us reduce errors and streamline processes, but we don’t want to lose control or personalized attention. It’s a combination of technological efficiency and human oversight,” he stated.

With this strategy, the company seeks to consolidate itself as a comprehensive logistics ecosystem in Mexico, capable of covering everything from physical operations to digital management of foreign trade, in an increasingly regulated and demanding environment.

It is worth remembering that the Tax Administration Service (SAT) announced the extension of the deadline for the entry into force of the MVE , which will now be mandatory from June 1, 2026.

El cargo TGX is committed to the Electronic Value Manifesto with a technological solution apareció primero en T21.

The Tax Administration Service (SAT) announced the extension of the deadline for the entry into force of the Electronic Value Declaration (MVE) , which will now be mandatory from June 1, 2026.

According to the agency, this mechanism is carried out through the Single Window for Foreign Trade (VUCEM) and is part of the efforts to strengthen the traceability and control of foreign trade operations.

The extension was published on March 30, 2026 in the First Resolution of Amendments to the General Rules of Foreign Trade (RGCE) for 2026.

In this resolution, rule 1.5.1, corresponding to the “Statement of Value”, was updated, as well as the Eleventh Transitory Provision of the provisions previously published in the Official Gazette of the Federation on December 27, 2025.

The SAT explained that the extension of the deadline seeks to give importers, exporters and other users of foreign trade the necessary time to adapt to the new obligation , as well as to have the appropriate technological tools for its compliance.

The tax authority also highlighted that this measure is part of its strategy to support the business sector in the transition to more digital, agile and transparent processes , facilitating regulatory compliance in customs matters.

With this adjustment, the implementation of the MVE is emerging as a key step in the modernization of foreign trade processes in Mexico, in a context of greater oversight and digitization of operations.
