Format E2 (MVE) requires you to declare which valuation method was used to determine the customs value of your imported goods. Mexico follows the WTO Customs Valuation Agreement, which establishes six methods applied in sequential order. Declaring the wrong method — or failing to justify why Method 1 doesn't apply — is one of the top reasons for customs audits and MVE rejections.
The transaction value is the price actually paid or payable for the goods when sold for export to Mexico, adjusted for additions (freight, insurance, royalties, assists) and permitted deductions. This is the primary method and must be used unless specific conditions prevent it. You can use Method 1 when there is a genuine sale, the price is not influenced by conditions that cannot be quantified, and the buyer and seller are not related — or if related, the relationship did not influence the price.
If Method 1 doesn't apply, use the customs value previously accepted for identical goods (same in all respects: physical characteristics, quality, reputation) exported to Mexico at approximately the same time. Adjustments are made for commercial level and quantity differences. This method requires access to historical import data for comparison.
Similar to Method 2 but uses goods that are not identical but closely resemble them in characteristics, components, and function. The similar goods must be commercially interchangeable with the goods being valued. Like Method 2, this method requires historical data and is adjusted for commercial level and quantity.
Method 4 (Deductive): Based on the selling price of identical/similar goods in Mexico, minus deductions for profit, taxes, duties, and transport. Method 5 (Computed): Based on cost of production plus profit and general expenses. Method 6 (Fallback): Flexible application of any previous method with reasonable adjustments. Methods 4 and 5 can be applied in reverse order at the importer's request.
The WTO agreement and Mexican Customs Law (Articles 64-78) require that methods be applied in order: try Method 1 first, then 2, then 3, and so on. You cannot skip directly to Method 5 without documenting why Methods 1-4 don't apply. The MVE (Format E2) has a section where you must justify your method selection.
Camtom's MVE module includes an interactive decision tree that guides you through the method selection process. Answer a series of yes/no questions about your transaction and Camtom will recommend the appropriate method, pre-fill the justification section of Format E2, and flag any documentation you need to support your choice.
Regardless of which method you use, keep all supporting documentation (invoices, contracts, price lists, cost breakdowns) for at least five years. Mexican customs authorities can request this documentation during an audit to verify your valuation methodology.
