How to Automate MVE Filing with Camtom

Why automate MVE filing?

Filing the MVE (Manifestación de Valor en Aduana) manually through VUCEM is time-consuming and error-prone. Each Format E2 has over 30 fields that must be filled correctly, the COVE must be properly linked, and the valuation method must be justified. Camtom automates this entire process: extracting data from your import documents, pre-filling every field, validating against VUCEM rules, and letting you sign and submit in under 5 minutes.

Step 1: Upload your import documents to Camtom

Start by uploading your commercial invoice and supporting documents (packing list, bill of lading, insurance certificate) to Camtom Docs. The AI-powered document reader extracts supplier information, product descriptions, quantities, prices, Incoterms, freight costs, and insurance — all the data needed for the MVE.

Step 2: Review the auto-filled Format E2

Navigate to the MVE module and select Create MVE from documents. Camtom populates Format E2 with the extracted data: importer information (from your profile), supplier details, transaction description, valuation method (defaulting to Method 1 — Transaction Value), and the full customs value calculation including incrementables.

Step 3: Validate before signing

Click Validate MVE. Camtom checks every field against VUCEM rules: correct RFC format, valid COVE reference, consistent values between invoice and valuation, proper valuation method justification, and complete incrementable declarations. Any issues are highlighted with clear explanations and suggested corrections.

Step 4: Sign with your e.firma

Once validation passes with zero errors, click Sign and Submit. Upload your .cer and .key files and enter your e.firma password. Camtom generates the signed XML document and submits it to VUCEM through the official web service (SOAP). The process takes seconds and Camtom displays the MNVA number immediately upon successful submission.

Step 5: Share the MNVA with your customs broker

The MNVA number is automatically available in the Camtom platform. If your broker uses TIM, the MNVA flows directly to the pedimento without any manual intervention. If your broker uses external software, copy the MNVA number from the MVE confirmation screen and share it securely.

1. Upload documents to Docs for automatic data extraction.
2. Review the pre-filled Format E2 in the MVE module.
3. Run validation to catch errors before signing.
4. Sign with your e.firma and submit to VUCEM.
5. Share the MNVA number with your customs broker for the pedimento.

Time savings comparison

Manual MVE filing on VUCEM: 30-60 minutes per filing, with a 15-20% error rate that requires re-filing. Automated MVE with Camtom: under 5 minutes per filing, with a less than 2% error rate thanks to pre-validation. For companies filing 20+ MVEs per month, this translates to saving over 15 hours of work monthly.
