What is a pedimento and how do you read one?

Why was this tariff code selected? What evidence supports the country of origin? How was the customs value built? An importer who can answer those three questions understands the core of the entry.

You do not need to memorize every pedimento key. You do need to recognize your company, your products, and the commercial facts. If a line looks unfamiliar, ask before transmission. The most useful broker relationship is not silent. It leaves the importer with a clear record of what was declared and why.

A pedimento is Mexico's electronic customs declaration for commercial imports and exports. It identifies the parties, merchandise, tariff classification, origin, customs value, regime, duties, and supporting records. An authorized customs professional prepares and transmits it, but the importer should still review the business facts. Treating it as a receipt with one amount at the bottom misses the fields that create future audit risk.

What is a pedimento and who prepares it?

The importer provides product, transaction, and registration information to the customs broker. The broker translates that file into the official declaration, attaches or references required digital documents, calculates charges, and transmits the entry through Mexico's customs system. The commercial invoice, bill of lading, origin evidence, permits, and value documents support the filing. They do not become interchangeable simply because they describe the same shipment.

• Importer and RFC: Legal party responsible · Importer records
• Tariff code: Classification and controls · Product specifications
• Origin and export country: Where made and routed · Origin evidence
• Customs value: Declared valuation basis · Invoice and payment
• Regime and keys: Legal customs treatment · Commercial purpose
• Contributions: Duty, IVA, and other charges · Broker calculation

Which mistakes matter most?

Country of shipment is often confused with country of origin. Goods shipped from a US warehouse are not automatically USMCA-origin goods. Product descriptions can also be too vague to support the selected code. Finally, value, currency, Incoterm, and payment evidence may conflict. Mexico's 2026 electronic value controls make those inconsistencies more visible before entry, so the commercial team and broker must use the same facts.

How should an importer review the document?

Compare legal name and RFC first. Then match each line to the invoice, quantities, weights, description, tariff code, origin, and value. Ask why a preference, permit, or tax treatment applies. Keep the final declaration and supporting evidence with the shipment record. We prefer a short pre-filing review for new products. Ten minutes before transmission is cheaper than a correction after release.

Keep a product master sheet

For repeat SKUs, store the approved description, material, use, origin, tariff code, unit value logic, and required permits. Give the broker controlled updates when the product changes. This reduces accidental drift between shipments. It also makes internal review much faster when a buyer or auditor asks what was declared.

Review it in three passes

1. Match the importer, supplier, invoice, regime, and customs office to the shipment.
2. Match each product line to quantity, unit, origin, tariff classification, and declared value.
3. Review duties, VAT, fees, preferences, permits, and attached electronic records.

Do not approve a line because the total looks familiar. A repeated SKU can still carry a changed origin, value, or specification. Keep the approved version with the invoice, payment evidence, classification note, and release record. If a correction is required, preserve both versions and the reason for the change.

Frequently asked questions

Is a pedimento the same as a commercial invoice?

No. The invoice records the transaction. The pedimento is the customs declaration supported by that invoice and other evidence.

Can an importer correct a pedimento?

Corrections may be possible depending on the field and timing, but they can create cost and scrutiny. Prevent the error before filing whenever possible.
