MVE vs. Manual Value Declaration: Why and How to Migrate to Digital

Manual vs. Digital: What Changes?

The transition from manual value declarations to the electronic MVE is not just a format change — it fundamentally alters the workflow. In the old process, the importer provided value information to the customs broker on paper or via email, the broker incorporated it into the pedimento, and there was no independent verification. With the MVE, the importer directly declares the transaction value through VUCEM, signs it with their own e.firma, and the system assigns a traceable MNVA number that links to the pedimento. This creates an independent audit trail that SAT can verify automatically.

Benefits of the Digital MVE

• Traceability: Every MVE has a unique MNVA number linked to the signing importer's RFC, creating a verifiable chain of custody for value declarations.
• Reduced fraud risk: The importer signs directly, eliminating the risk of value manipulation between the importer and the pedimento filing.
• Faster processing: Electronic filing and validation is faster than paper-based processes, reducing delays at the port.
• Audit readiness: Digital MVEs are stored in VUCEM and retrievable instantly during audits, eliminating the need to locate paper records.
• Integration capability: MVEs can be generated and filed via API, enabling full automation for high-volume importers.

The biggest challenge in migration is organizational, not technical. Importers need to understand that they — not their customs broker — are responsible for signing the MVE. This requires having a current e.firma, designating authorized personnel, and establishing a workflow for MVE preparation and signing. Camtom bridges this gap by providing a portal where customs brokers prepare the MVE data and importers sign with a few clicks, streamlining the collaboration between both parties.
