Importing into Mexico without an importer registry: how an importer-of-record works

One of the first barriers to foreign trade in Mexico is the importer registry (padrón de importadores) at the SAT. Without being enrolled, a company cannot import goods under its own name — and registering requires being current with tax obligations, holding a valid e.firma, demonstrating financial capacity, and often waiting weeks for the SAT to resolve.

For SMEs that import occasionally or want to test the market before committing to the paperwork, the standard solution is to operate through an importer-of-record (IOR) — what in Mexico we call a comercializadora.

What is an IOR / comercializadora

An importer-of-record is a company that is registered in the importer registry and imports goods under its own name. Once the goods are nationalized (duties paid and customs cleared), it sells them to you as a domestic purchase, with a Mexican invoice.

From a tax and operations standpoint:

• You do not appear as the importer before the SAT.
• You receive a domestic invoice, just as if you bought from any Mexican supplier.
• You can deduct VAT (16%) like any local purchase.
• You don’t need an e.firma, a registry, or foreign trade tax filings.

When the IOR model makes sense

Cases where it’s a good fit:

1. You import a few times a year. Keeping the registry active costs administrative time and compliance overhead that only pays off with recurring volume.
2. Your company is new and hasn’t yet completed the registry requirements.
3. You want to test a foreign supplier before committing to formal operations.
4. Your end client requires a Mexican invoice and won’t accept international invoicing.
5. You import goods with special permits (NOMs, sanitary, phytosanitary) and prefer an expert to manage them.

Cases where it’s not the right fit:

• You import with high recurring volume (monthly). Here, owning the registry gives you better margin since you eliminate the IOR’s spread.
• Your product requires certifications only you as the manufacturer can hold (some regulated sectors).

How the flow works in practice

1. You negotiate with the foreign supplier on commercial terms (price, INCOTERM, lead time).
2. The IOR purchases from your supplier with its own invoice and assumes responsibility for the shipment.
3. It coordinates forwarding and customs clearance from origin to warehouse.
4. It pays import duties (general import tax, VAT, customs processing) at the border.
5. It invoices you as a domestic purchase once the goods clear customs.
6. It delivers to the destination you specify.

The price you pay the IOR includes: cost of goods + freight + insurance + duties + operator margin. Properly structured, the operator’s margin is transparent and competitive against what doing it yourself would cost (including your administrative overhead).

What risks to watch

The main risk is working with an IOR that does not operate transparently. Red flags:

• They don’t show you the customs entry (pedimento).
• They don’t break down costs.
• They invoice a single line item with no detail.
• They don’t have a verifiable tax address or identifiable operations team.

A healthy operation is fully documented: you should receive a copy of the customs entry, the foreign supplier’s invoice (to the IOR), and your domestic invoice with a detailed breakdown.
