The Electronic Customs Value Manifestation (ECVM) has become a key element in international trade operations in Mexico. With its mandatory implementation through VUCEM, companies must ensure that the information submitted is accurate, complete, and consistent.
However, while the regulatory framework is well defined, in practice many importers still make mistakes as part of the natural learning curve. These errors can lead to penalties, delays in customs clearance, or even audits by the authorities.
Below, we outline the most common mistakes related to the Electronic Customs Value Manifestation and how to avoid them.
1. Inconsistencies in the Declared Value
One of the most frequent issues is when the information reported in the ECVM does not match:
- Commercial invoice
- Contracts
- Proof of payment
This can trigger alerts from the authorities and lead to more detailed inspections.
How to avoid it:
Ensure that all documents reflect exactly the same value and commercial terms.
2. Omission of Dutiable Additions
Dutiable additions (such as freight, insurance, commissions, or packaging) are part of the customs value under Mexican Customs Law.
Failing to declare them properly may result in:
- Undervaluation
- Penalties
- Post-clearance corrections
How to avoid it:
Identify all costs associated with the transaction and verify whether they must be included in accordance with Article 65 of the Customs Law.
3. Incorrect INCOTERM Declaration
The INCOTERM defines which costs are included in the price paid.
An error in this area can lead to:
- Incorrect customs value calculation
- Inconsistencies in the ECVM
- Issues with customs authorities
How to avoid it:
Verify that the declared INCOTERM matches the contract and the commercial invoice.
4. Lack of Supporting Documentation
The ECVM must be supported by a complete file that includes:
- Commercial invoice
- Transport documents
- Proof of payment
- Contracts
- Evidence of additional costs
Not having this documentation can complicate audits or post-clearance reviews.
How to avoid it:
Maintain a well-organized and accessible digital file at all times.
5. Lack of Internal Coordination
One of the most common issues is not technical, but organizational.
When departments such as finance, logistics, or legal are not aligned, inconsistencies in the declared information can arise.
How to avoid it:
Centralize information and establish clear validation processes before submitting the ECVM.
6. Submitting Information Without Prior Validation
Submitting the ECVM without reviewing the data can result in errors that later require:
- Corrections
- Penalties
- Delays in customs clearance
How to avoid it:
Implement internal controls or pre-submission audits to validate all information before filing.
7. Not Updating Internal Processes for the New Digital Mode
The ECVM is not just another requirement—it represents a shift in how information is managed.
Companies that continue to rely on manual processes face a higher risk of errors.
How to avoid it:
Update your systems, automate processes, and ensure your operations are aligned with digital requirements. When necessary, work with a customs agency to support proper implementation.
