A free trade agreement doesn’t lower your duties automatically. It lowers duties on goods that **qualify as originating** and that **prove it with a document**. Without that document you pay the general rate even if your product ships from Texas. It’s the single biggest pile of money left on the table in Mexican trade.

## First things first: “where it ships from” ≠ “where it originates”

**Origin** is a legal concept, not a geographic one. Goods are USMCA-originating if they meet the **rule of origin** for their tariff code: they were wholly obtained in the region, their non-originating inputs underwent a **tariff classification shift**, or they hit a minimum **regional value content**.

> Practical translation: a product assembled in the United States with Chinese parts **may or may not** be USMCA-originating. It depends on the rule for its tariff code. Assuming it without checking is signing up for a tax assessment for improperly claimed preference.

## How certification works under USMCA

Unlike the old NAFTA, USMCA **has no official form**. The certification of origin is a statement that can go on the commercial invoice or on a separate document, and it can be issued by the **exporter**, the **producer** or the **importer**.

## The 9 minimum data elements

- Who certifies: **importer, exporter or producer**
- Name, address, phone and email of the **certifier**
- **Exporter** details (if different)
- **Producer** details (or a note that they’re withheld)
- **Importer** details
- **Description and tariff classification** (to at least 6 digits)
- The applicable **origin criterion**
- **Blanket period** (a single shipment or a blanket certification of up to 12 months)
- **Signature, date and the statement** that the information is true

Miss one and the authority can deny the preferential treatment. Run through them as a checklist — literally.

## The 5 mistakes that kill the benefit

- **Certifying with nothing behind it.** The supplier signs “because we always sign it” and never actually ran the rule of origin. In a verification, the tax bill lands on the **importer**.
- **A description that doesn’t match** the invoice and the customs entry (pedimento).
- **The wrong classification** on the certification: it changes the applicable rule and, with it, the criterion.
- **An expired blanket certification.** It covers up to 12 months; shipment 13 needs a new one.
- **Not declaring it on the customs entry.** You can hold a perfect document: if the identifier isn’t declared, you pay the general rate anyway.

## Keep it for 5 years

The retention obligation is **five years** and — this is the key part — it includes the **records that support origin**: bills of materials, regional value content calculations, input invoices. If you get verified, “my supplier said it qualified” is not a defense.

## What about the other treaties?

Mexico has one of the widest treaty networks in the world: **USMCA, CPTPP, the agreement with the European Union, the Pacific Alliance** and several more. Each has its own certification format or mechanism and its own rules of origin — the principle is the same: qualify, document, declare.
