Definition
The Electronic Value Manifestation (MVE) is the electronic declaration, transmitted by the importer through VUCEM (format E2) and signed with their e.firma, stating the customs value of the goods. Including elements that increase or decrease it. As support for the pedimento’s taxable base. It moves the former paper manifestation into an electronic channel; verify mandatory dates and current rules in SAT, DOF, and RGCE.
Your broker asks for the MVE folio and the pedimento cannot be paid. It is not a VUCEM “extra”: it is the Electronic Value Manifestation the importer must transmit and sign. If the incrementables file is incomplete, the declared value does not hold.
This entry defines what MVE is, who signs, why it anchors the taxable base, and how it differs from paper. For the ops flow see how to file MVE in VUCEM; for the contrast with Value Acknowledgment, MVE vs COVE. Full guide: MVE 2026.
What MVE is and what it is for
In Mexican practice, MVE is the formal value file: invoice prices, freight, insurance, commissions, and other concepts that affect customs value, declared electronically to the authority via VUCEM.
It is not an “internal broker form.” It is an importer act. The customs broker can build the support package and run the pedimento, but the electronic signature on the MVE belongs to the importer (e.firma).
Always verify the current RGCE / DOF / SAT portal text: mandatory timelines and transmission rules have had extensions and coexistence stages.
Who signs: importer vs customs broker
Clear operating rule: the importer signs with their e.firma. Delegating “the broker signs the MVE” is not how the electronic scheme is designed.
What the broker or your trade-ops team can do is prepare the file (invoices, COVEs, reconciled freight/insurance) and load VUCEM data for the importer to sign. An MVE support agent. Like OCL Cargo’s. Builds that per-pedimento package ready for VUCEM without replacing e.firma.
Importer
What they do on MVE: Declare, review, sign with e.firma; own the value
What they do NOT do: Transfer the signature to the broker as if it were theirs
Customs broker (AA)
What they do on MVE: Advise, integrate pedimento, use the MVE folio
What they do NOT do: Sign the MVE in place of the importer
Trade ops / 3PL docs
What they do on MVE: Gather invoices, COVE, freight, insurance; check consistency
What they do NOT do: Assume legal responsibility for the declared value
VUCEM (E2)
What they do on MVE: Transmission channel and acknowledgment/folio
What they do NOT do: Validate for you that the economic value is “correct”
Why it anchors the taxable base
Customs value drives IGI, DTA, and other duties that depend on that base. An incomplete MVE or one inconsistent with pedimento/COVE/invoice risks observation, value adjustment, or fines. Without inventing amounts: confirm ranges in the current LFD / resolutions.
Incrementables (freight to the first point of entry, insurance, buying commissions, etc., depending on the case and the rule) must be documented. If you pay international freight and omit it when required, value is short versus economic reality.
For trade ops in Mexican import (manufacturing, retail, or foreign-trade 3PL), MVE concentrates what used to live in shared folders: EXW/FOB invoice, international freight via forwarder, insurance, and commissions. The customs/TMS buyer does not delegate value to the broker: the importer signs, but ops must deliver the reconciled file before E2.
Paper vs electronic: what changes in 2026
Paper required a physical file and manual steps; MVE concentrates the declaration in VUCEM with a digital trail and a folio for the pedimento.
Many ops sources cite coexistence of the prior scheme through 31 May 2026 and mandatory electronic transmission from 1 June 2026. SAT has published extensions: do not operate from a LinkedIn post alone. Confirm DOF/RGCE on the day you clear.

Myths and common mistakes
1.Myth: “The broker signs the MVE for us”
Electronic MVE is signed with the importer’s e.firma. The broker runs the pedimento and uses the folio; they do not replace that signature.
VUCEM E2 design
2.Mistake: Confusing MVE with COVE
COVE is the Value Acknowledgment (related support). MVE is the formal value declaration. You may need both; they are not synonyms. See MVE vs COVE.
Related, not identical
3.Myth: “If the invoice shows price, there are no incrementables”
Freight, insurance, and commissions can change customs value even when the invoice shows goods only. Document under RLA / RGCE 1.5 and applicable cases.
4.Mistake: Pedimento paid without MVE folio (when already required)
The folio must go on the pedimento before duties are paid under the electronic scheme. Delaying MVE “for later” breaks clearance.
Folio ~13 characters
5.Myth: “2026 dates will not move again”
There have been extensions. Treat 1 Jun 2026 / 31 May 2026 as frequent market citations, not immutable truth without DOF.
Next step for trade ops
If you already know what MVE is, the bottleneck is usually process: E2, e.firma, folio a pedimento. Follow how to file MVE in VUCEM and the mistakes and penalties checklist.
For SAT goods/complement codes, the SAT code finder speeds document cross-checks. It does not replace MVE.

Key takeaways5 points
- MVE is the electronic customs-value declaration filed by the IMPORTER in VUCEM (format E2), signed with the importer’s e.firma. Not the customs broker’s.
- It supports the taxable base: goods value + incrementables/decrementables under the Customs Law and applicable rules (verify current RGCE / DOF).
- Unlike paper, MVE issues a folio (~13 characters) that must go on the pedimento before duties are paid.
- COVE (Value Acknowledgment) is related but distinct: it supports the file; MVE is the formal value declaration.
- 2026 dates: many sources cite mandatory electronic filing from 1 June 2026 and coexistence through 31 May 2026. always confirm SAT/DOF/RGCE.

Frequently asked questions
It is the electronic customs-value declaration the importer transmits in VUCEM (format E2) and signs with their e.firma, supporting the pedimento’s taxable base. Confirm current rules and dates in SAT/DOF/RGCE.
The importer, with their e.firma. The customs broker can prepare the file and pedimento, but is not responsible for signing the MVE in the importer’s place.
Ops sources often cite mandatory filing from 1 June 2026 and coexistence through 31 May 2026. SAT has extended deadlines: verify the DOF/RGCE applicable to your clearance date.
Electronic filing goes through VUCEM, leaves a digital trail, and issues a folio for the pedimento. Paper was a physical/manual file; the purpose (declare value) is the same, the channel and controls change.
No. COVE is the Value Acknowledgment; MVE is the formal value declaration. They relate in the file but play different roles. See the MVE vs COVE comparison in this glossary.
OCL Cargo’s MVE agent builds per-pedimento support (invoices, incrementables via reconciled COVE) ready for VUCEM. E.firma remains the importer’s; the agent cuts document friction, it does not replace the declaration.
