What Foreign Companies Need to Import into Mexico

Key takeaways

Someone in Mexico must be the importer. Defining that role is the first decision.
The importer generally needs an active RFC, a valid e.firma, a positive tax compliance status and registration in the Padrón de Importadores.
A licensed customs broker files the import declaration (pedimento). The importer remains responsible for the accuracy of the information.
Tariff classification, origin, valuation and product standards (NOMs) should be reviewed before goods ship.

Start with one question: who is the importer?

Every import into Mexico has an importer: the party that appears on the customs declaration and is responsible for taxes, duties and compliance. A foreign company can import through its own Mexican entity, or through a local company that acts as importer on its behalf. That choice drives every requirement that follows, so it should be decided and documented before anything ships.

It also should not be implied. The importer of record, the legal representative and the customs broker are distinct roles, each with its own legal responsibilities.

Registrations the importer needs

According to the SAT, registration in the Padrón de Importadores is required to import goods for commercial purposes [1]. In practice, importers are expected to have:

An active RFC (tax ID) and valid e.firma (advanced electronic signature).
A positive tax compliance opinion.
A fiscal address the authority can locate, and an enabled tax mailbox (Buzón Tributario).
Registration in the Padrón de Importadores, with the customs broker(s) authorized to act for them.
Where the products fall in certain sensitive categories, registration in the Padrón de Importadores de Sectores Específicos [2].

Registration is not permanent. It can be suspended if the importer's tax status changes, so it needs to be monitored as part of normal operations, not treated as a one-time task.

The customs broker and what they need from you

Formal imports are filed by a licensed customs broker (agente aduanal) or customs agency through the import declaration, the pedimento. The broker needs a formal mandate from the importer and accurate information to work with. That typically means:

A commercial invoice and packing list with complete, consistent product descriptions.
Transport documents, such as the bill of lading or air waybill.
Product data for tariff classification: materials, function, composition and technical specifications.
Proof of origin where preferential treatment is claimed, such as under the USMCA.
Information supporting customs value, and any permits, certificates or standards compliance required for the product.

Mexico's 2026 customs reform increased the responsibilities of both importers and customs brokers, including documentation and verification expectations [3]. Brokers are now more demanding about the information they receive. Incomplete supplier documents are one of the most common causes of delay.

PCG is not a customs broker. We coordinate import operations with qualified, licensed customs brokers and specialists when required.

Product checks before the first shipment

Tariff classification

The tariff classification (fracción arancelaria) determines duty rates, non-tariff requirements and whether a sector-specific registration applies. It should be reviewed with a customs specialist, not guessed from a supplier's HS code.

Origin and duties

Origin matters more than it used to. Starting in January 2026, Mexico raised duties on 1,463 tariff lines for goods from countries without a trade agreement with Mexico, with rates of up to 50% in some sectors [4]. Goods that qualify under agreements such as the USMCA may receive different treatment, provided origin is properly supported.

Standards and labeling (NOMs)

Many consumer products must meet Mexican Official Standards (Normas Oficiales Mexicanas) before sale, most visibly commercial labeling in Spanish. Some categories also require certification. Identify the standards that apply to each product early, because relabeling or certification after arrival is expensive.

Taxes at import

Imports typically carry general import duty (unless reduced by a trade agreement), value-added tax and customs processing fees, plus other taxes or countervailing duties for specific products. Your customs broker and tax advisor should model these before you set prices.

Tariff classification reviewed for each SKU.
Origin documentation and valuation support prepared.
Applicable NOMs identified and labeling plan confirmed.

Frequently asked questions

Can a foreign company import into Mexico without a Mexican entity?

A foreign company generally imports through a Mexican importer, either its own Mexican entity or a local company acting as importer. Which structure fits depends on your volumes, channels and risk profile, and should be confirmed with qualified legal, tax and customs advisors.

Is PCG a customs broker?

No. PCG coordinates import operations: documentation, suppliers, freight, broker handoffs and milestones. Customs clearance is performed by qualified, licensed customs brokers.
