Complete Guide: How to Import Products to Mexico in 2026

Importing products to Mexico may seem like a complex process, but with the right information and proper guidance, it becomes a smooth and profitable operation. In this guide, we explain the essential steps every importer should know.

1. Tariff Classification

The first step —and perhaps the most important— is determining the correct tariff code for your product. This classification determines:

• The percentage of taxes you'll pay
• The applicable regulations and restrictions
• Any additional permits you may need

Tip: An incorrect classification can result in significant fines or even the retention of your goods at customs.

2. SAT Registration

To import into Mexico, you need to be registered in the Importers' Registry (Padrón de Importadores) with the SAT. Requirements include:

• Active and current RFC (tax ID)
• Verified fiscal address
• Up-to-date tax obligations
• Current e.firma (electronic signature)

3. Required Documentation

Each import requires specific documentation:

• Import declaration (Pedimento) — the main customs document
• Commercial invoice — from the foreign supplier
• Bill of Lading or Air Waybill
• Certificate of origin — if tariff preferences apply (USMCA, for example)
• Prior permits — depending on the product type (COFEPRIS, SEMARNAT, etc.)

4. Customs Broker

In Mexico, a customs broker (agente aduanal) is mandatory for foreign trade operations. This professional:

• Prepares the import declaration
• Classifies your merchandise
• Calculates taxes and duties
• Represents your interests before customs
