Step-by-step guide to filling the MVE in VUCEM

Before you start: what you need ready

Before starting the MVE in VUCEM, make sure you have: your valid e.firma (.cer and .key files with password), the supplier's commercial invoice, the international sales contract (if applicable), identified additions list, and the tariff code for the goods.

Step 1: Access VUCEM and select the MVE module

Log into VUCEM (ventanillaunica.gob.mx) with your e.firma. Navigate to the Value Declaration module and select 'New Declaration'. The system will present Format E2 divided into sections to complete in order.

Step 2: Importer data

Complete the importer data: RFC (tax ID), company name and fiscal address. These fields auto-populate from your e.firma, but verify they are correct.

Step 3: Supplier data and conditions of sale

Enter the foreign supplier data: name, country of residence and address. Indicate whether a relationship exists between your company and the supplier per Art. 68 of the Customs Law criteria.

Step 4: Goods description

For each item: tariff code (8 digits), commercial description, quantity, unit of measure, unit price and total value. Multiple products in a single declaration each require their own line in the MVE.

Step 5: Transaction value and additions

The transaction value is the price actually paid or payable for the goods. Add the additions under Art. 65 of the Customs Law: selling commissions and brokerage (section I), containers and packaging (section II), materials and technical assistance provided (section II), royalties and license fees (section III), and resale proceeds reverting to the seller (section IV).

Step 6: Deductions

Deductions under Art. 66 LA are amounts you can subtract from the transaction value: inland transportation in Mexico, post-import construction or installation costs, interest payments and charges not part of the price.

Step 7: Valuation method

Indicate which of the six WTO Valuation Agreement methods you are using. Method 1 (transaction value) is the most common. If Method 1 cannot be used, methods must be applied in successive order from 2 to 6.

Step 8: Sign and transmit

Once all fields are complete, review carefully. Sign the MVE with your e.firma and transmit. VUCEM will return an MNVA number to provide to your customs broker for inclusion in the customs declaration.
