What Documents Do You Need To Ship Freight To Mexico?

To ship freight from Texas to Mexico you need a commercial invoice, a packing list, a certificate of origin to claim USMCA duty-free treatment, and a pedimento, Mexico's official import declaration, prepared and filed by a licensed Mexican customs broker. Most goods also need Spanish NOM labeling, and some need sanitary or sectoral permits. Getting these consistent and complete is what keeps the load moving.

• The core documents are the commercial invoice, packing list, certificate of origin and pedimento (SAT, licensed broker).
• The pedimento is Mexico's official import declaration and can only be prepared and filed by a licensed Mexican customs broker (agente aduanal).
• A certificate of origin lets US-origin goods clear duty-free under USMCA; without it, goods pay the general tariff (USTR, SAT).
• Import IVA is 16 percent nationwide on the customs value, paid via the pedimento (SAT).
• Most retail goods need Spanish NOM labeling to enter, and some need sanitary (COFEPRIS) or sectoral permits.

What documents do I need to ship freight from Texas to Mexico?

A commercial invoice, a packing list, a certificate of origin to claim USMCA duty-free treatment, and a pedimento filed by a licensed Mexican customs broker. Most goods also need Spanish NOM labeling, and some need sanitary or sectoral permits. These few documents, done consistently, are what clear the load.

Shipping freight from Texas to Mexico runs on a short but strict set of documents, and getting them right is the difference between a load that crosses in a day and one that sits at the border. The core set is four documents. The commercial invoice describes the goods, their value and the parties; it is the basis for customs valuation, so it must be accurate and internally consistent. The packing list details what is in each box or pallet, which speeds physical inspection and reconciliation. The certificate of origin proves the goods are US-origin under USMCA, which is what unlocks duty-free entry; without it, otherwise-qualifying goods pay the general tariff. And the pedimento is Mexico's official import declaration, the master customs document, which only a licensed Mexican customs broker, an agente aduanal, can prepare and file, and through which the 16 percent IVA and any duty are paid. Beyond those four, most retail goods need Spanish NOM labeling to be admitted and sold, and some categories, such as food, cosmetics or medical goods, need sanitary permits from COFEPRIS, while sectoral goods may need padrón sectorial registration. The most common failure is not a missing exotic form but inconsistency, where the invoice, packing list and origin document disagree on value, quantity or description. BringGo Ship checks these documents for consistency, applies the Spanish labeling, and files the pedimento through its licensed broker, so the paperwork clears rather than stalls.

Why does the certificate of origin matter so much?

Because it is what makes US-origin goods duty-free entering Mexico under USMCA. Without a valid certificate, otherwise-qualifying goods pay the general tariff, which can erase margin. Under USMCA the exporter, producer or importer can certify, on an invoice or any document, using nine required data elements, with no official government form.

Of all the documents, the certificate of origin deserves special attention because it directly controls how much duty you pay. Under USMCA, US-origin goods that qualify can enter Mexico duty-free, but that treatment is not automatic: it must be claimed with a valid certification of origin. Without one, goods that would have qualified instead pay Mexico's general tariff, which on many product lines is enough to wipe out the margin on the shipment. A few facts make this document less intimidating than it looks. First, under USMCA there is no official government form and no pre-approval, unlike the old NAFTA certificate; the certification can be provided on the commercial invoice or any other document. Second, any of three parties can certify, the exporter, the producer or the importer, a change from NAFTA's exporter-only rule. Third, it must contain nine minimum data elements, including who is certifying, the parties, a description with the HS classification to the six-digit level, the origin criterion and a signature and date. Fourth, a single certification can cover multiple shipments of identical goods over a blanket period of up to twelve months, while the document itself must be accepted for four years, two distinct periods that are easy to confuse. Because the rules of origin behind qualification can be technical, and because the 2026 USMCA joint review may revisit some sectoral thresholds, it is worth confirming a product genuinely qualifies before certifying. BringGo Ship helps ensure the origin claim is valid and consistent with the invoice, so the duty-free treatment holds up.

Who prepares each document, and how do I avoid delays?

You or your exporter prepare the commercial invoice, packing list and certificate of origin; a licensed Mexican customs broker prepares and files the pedimento. Delays come mostly from inconsistency between documents. Prepare them together at a border warehouse, check that value, quantity and description match, and apply labeling before the goods cross.

Knowing who prepares what, and where the delays actually come from, is how you keep a load moving. On the export side, you or your exporter prepare the commercial invoice, the packing list and the certificate of origin, because these describe your goods, your prices and your origin claim. On the import side, only a licensed Mexican customs broker, the agente aduanal, can prepare and file the pedimento, which is why cross-border freight effectively involves a broker on the Mexican side regardless of who handles the US side. The single biggest source of delay is not a missing document but inconsistency between them: the invoice says one value, the packing list a different quantity, the origin document a different description, and customs stops the load to reconcile it. The second biggest is discovering a labeling or permit requirement at the border, when it is expensive and slow to fix, rather than before crossing, when it is cheap. The way to avoid both is to prepare the documents together and check them against each other before the goods move, ideally at a border warehouse where the goods, the labels and the paperwork are in one place. That means confirming the invoice, packing list and certificate of origin agree on value, quantity and description; applying the Spanish NOM labeling; and confirming any sanitary or sectoral requirement in advance. BringGo Ship does exactly this at its Laredo warehouse, reconciling the documents, labeling the goods and filing the pedimento through its broker, so the load crosses on the first attempt.

Frequently asked questions

What documents do I need to ship freight to Mexico?

A commercial invoice, a packing list, a certificate of origin to claim USMCA duty-free treatment, and a pedimento filed by a licensed Mexican customs broker. Most goods also need Spanish NOM labeling, and some need sanitary (COFEPRIS) or sectoral permits. Consistency across these documents is what clears the load.

Who can prepare the pedimento?

Only a licensed Mexican customs broker, an agente aduanal, can prepare and file the pedimento, Mexico's official import declaration. This is why cross-border freight into Mexico effectively requires a Mexican broker regardless of who handles the US side, and it is through the pedimento that the 16 percent IVA and any duty are paid.

Why does the certificate of origin matter so much?

Because it makes US-origin goods duty-free entering Mexico under USMCA. Without a valid certificate, otherwise-qualifying goods pay the general tariff, which can erase margin. Under USMCA the exporter, producer or importer can certify, on an invoice or any document, using nine required data elements, with no official government form.

What causes most customs delays?

Inconsistency between documents is the biggest cause: the invoice, packing list and certificate of origin disagreeing on value, quantity or description, which makes customs stop the load to reconcile. The second is discovering a labeling or permit requirement at the border. Preparing and checking documents together before crossing avoids both.

Do I need Spanish labeling as well as documents?

Yes, for most retail goods. Beyond the customs documents, most products need Spanish NOM labeling to be admitted and sold in Mexico, and some categories need sanitary or sectoral permits. Applying the labeling before the goods cross, at a border warehouse, avoids a hold at the border where fixing it is slow and costly.

How much tax do I pay on freight into Mexico?

Import IVA is 16 percent nationwide on the customs value, paid through the pedimento. Duty depends on origin and classification: US-origin goods with a valid certificate of origin generally clear duty-free under USMCA, while goods that cannot prove qualifying origin pay the general tariff on top of the IVA.
