Customs guides for Mexico

Prepare your Mexican import or export with a guide for the question you have now. Each guide explains the information to gather, the points to review and the customs broker's role in the shipment.

How to choose a customs broker in Mexico

Choose a customs broker around your goods, importer setup and crossing plan. Before you book transport, ask who will prepare the filing, what they need to review and how you will receive shipment updates.

What goes into the cost of a Mexican customs broker

A customs clearance quote brings together the government charges and services relevant to your shipment. Review the components and scope with the customs broker; actual costs come from that shipment review.

Pedimento explained: how to read one

Read a pedimento (customs declaration) by matching its shipment, importer and product details to your supporting documents. Use SAT's current filling instructions to understand the fields, and ask the customs broker to explain any difference you find.

Padrón de importadores suspended: causes and reinstatement

Start with the specific reason stated in your SAT suspension notice for the padrón de importadores (importer register), then organize evidence addressing that reason. Filing a request to lift a suspension does not establish that the importer is reinstated or that a shipment can proceed.

USMCA/T-MEC certification of origin: when it is used and who signs

A USMCA certification supports a claim for preferential treatment when goods satisfy the agreement's origin rules. Confirm the product's origin basis before asking a supplier, producer or importer to certify it.

Mexico's 2026 tariff changes: goods and origins to review

Mexico's 2026 tariff changes affect listed product classifications, with separate effective dates. Review your goods, manufacturing origin and any treaty or program treatment; consult the linked DOF publications for the actual rates.

Official reference: DOF: tariff decree effective January 2026 · DOF: tariff and sector-program decree effective April 2026

Importing Chinese-origin goods into Mexico through the US

Keep Chinese manufacturing origin separate from a US seller or pickup location. Plan the US movement and Mexican import as distinct responsibilities, with product and origin evidence reviewed before you book the crossing.

IMMEX versus definitive import: which regime needs review?

Start with what the goods will be used for and whether they are intended to remain in Mexico. An IMMEX (export manufacturing and services program) operation needs review of the company's actual authorization and production flow; it is not a general option selected by a product name.

Official reference: Secretaría de Economía: IMMEX overview

Carta Porte for cross-border freight

Plan the Mexican transport document alongside the carrier handoff and customs file. Ask who will issue the applicable CFDI (Mexican digital tax invoice) with Carta Porte (transport supplement) and make sure that person receives the actual cargo and route information.

Official reference: SAT: Carta Porte guidance

NOM labeling and compliance at the border

Review the exact product and its classification before deciding which NOM (Mexican official standards) questions apply. Gather specifications, existing labels and supplier evidence before the goods are dispatched, so unresolved compliance work can be discussed with the customs specialist.

What to do when customs holds your shipment

Find out the exact stage and obtain the actual notice or document request before deciding what to do. Coordinate the response with the customs professional handling the shipment; a status message alone does not explain the legal or factual issue.

Importing solar panels and batteries into Mexico for your home

Plan the product review and transport arrangement before buying a home solar system abroad. List the panels, batteries and other equipment separately, then request a quote for the goods and destination you actually have in mind.

Bringing building materials across the border for a home build

Review the actual building products and delivery plan before collecting them abroad. List materials, fixtures and equipment separately, and ask for a quote that addresses your home project without treating personal use as an import approval.

Shipping to Mexico DDP versus DAP: who is the importer?

Ask who will appear as the Mexican importer before relying on a seller's DDP or DAP proposal. The delivery term and the importer arrangement need to be read together with the actual contract, goods and customs file.

Exporting from Mexico to the US: preparing the Mexican side

Prepare the Mexican export file and the US receiving arrangement as separate parts of the same movement. Start with the goods, exporter, buyer and route, then ask the customs specialist what needs review on the Mexican side.

Baja California border-zone imports: Tijuana, Otay and Tecate

Plan a Baja California import around the actual goods, importer and final destination. Review the proposed crossing and any later inland movement with the customs specialist before treating a border-zone arrangement as the complete plan.
