Every import into Mexico stands on a document file. If one document is missing or inconsistent, the operation stops — and every stopped day means storage and demurrage. This is the master list:

## The must-haves

| Document | Who issues it | What it’s for |
| --- | --- | --- |
| **Commercial invoice** | Your supplier | The basis for customs value |
| **Transport document** (BL, AWB or waybill) | The carrier/forwarder | Covers the cargo and its route |
| **Packing list** | Your supplier | Package detail for the origin inspection (previo) |
| **Customs entry (pedimento)** | Your customs broker | The declaration filed with the tax authority (SAT) |
| **Broker authorization (encargo conferido)** | You (SAT portal) | Authorizes your broker to clear your goods |

## The ones that depend on your product

- **Certificate / declaration of origin** — for a preferential treaty rate (USMCA, CPTPP…). Without it you pay the general rate, even though the treaty exists.
- **Product standards (NOMs)** — certificates or attestations (labeling, safety) depending on your tariff code.
- **Prior permits** — from the health (COFEPRIS), defense (SEDENA), environment (SEMARNAT) or economy (SE) authorities, depending on the goods.
- **Sector registry** — if your tariff code sits in a sensitive sector.
- **Value declaration (MVE)** — the statement of how your customs value was built.

Not sure what applies to YOUR product? [Look up your tariff code in the calculator](https://www.freightspot.com/en/tariff-calculator) and check its regulatory file: NOMs, permits and restrictions by code.

## The advice that saves the most money

> **Build the file BEFORE the goods ship.** 80% of customs problems start with documents nobody reviewed until the cargo was already at the port. A 30-minute document check saves weeks of delay.
