Master guide
How to import into Mexico, step by step
Importing well isn’t a single procedure: it’s a chain of decisions that starts before you close the purchase and ends when the goods reach the domestic market. This guide brings our articles together, organized by the real stage of an import operation — from how to get in to how to comply without surprises.
Step 1
How to get in: programs and regime
Importing into Mexico doesn’t always mean starting from scratch. Before your first shipment, it pays to know whether you can operate without being on the importer registry, whether a trade program (IMMEX, PROSEC) fits you, and which customs regime applies to your goods.
