COEXAcademy

A free school of foreign trade · Mexico and the US–Mexico corridor

Foreign trade, explained and up to date.

COEX Academy teaches customs, tariff classification and logistics from the law in force. Every lesson cites the article or tariff line it explains, and when the DOF amends them, the lesson is reviewed before you read it.

One account, four pillars

Everything you need to understand a shipment, in one place.

Learn, look it up, stay informed and ask: four tools that share the same source.

  • 01

    Aula

    The classroom: learning paths with lessons, exercises on real data and assessments. Finish a path and receive a certificate anyone can verify online.

  • 02

    Biblioteca

    The library: laws, regulations, general rules and the tariff, article by article and line by line, with their amendment history.

  • 03

    Radar

    Every morning we review the DOF and the US publications that touch foreign trade, and tell you what changes in what you follow.

  • 04

    Pregúntale

    Ask COEX: an assistant that answers only from the Biblioteca and cites every statement to the provision in force. When there is no basis, it says so.

Lessons bound to the law

A lesson that knows when the law changed.

Foreign-trade courses age with every reform. Here, each lesson keeps an exact reference to what it teaches, and that reference has a date.

  1. Exact citation

    Each lesson links the article, the fracción or the tariff line it explains, in the version in force on a given date.

  2. Daily reading

    Every morning the Radar reads the Diario Oficial de la Federación and identifies the provisions a publication amends.

  3. Flagged before you read

    If an amendment touches a cited provision, the lesson is marked “under review” before you read it.

  4. Human review

    A person reviews the change, updates the lesson and publishes it again. You see what changed and since when.

From the source, not from third parties

We cite the original publication.

The Biblioteca is built from what the institutions that issue or compile the rules publish, and every text keeps its reference. COEX Academy is not affiliated with any of them.

Biblioteca

The law as it stood on the day that matters.

Read any law as in force on a date, compare two versions with the changes marked, and follow the references: what an article cites and what cites it.

The tariff brings together, by tariff line and NICO, duties by origin and agreement, taxes, non-tariff regulations and their history.

Radar

What changed today, in what you follow.

Every morning the Radar reviews the DOF and, on the US side, the Federal Register and CBP's messages. Each relevant publication is summarized, linked to the provisions and tariff lines it changes, and sent to whoever follows them.

A sample of 2025 and 2026 publications. Dates are DOF publication dates; always check the published text.

Questions

What people usually ask us.

All questions

What is COEX Academy?

A free school of foreign trade, in Spanish first, that teaches from the law in force. One account brings four pillars together: the Aula (learning paths), the Biblioteca (laws and tariff with date and source), the Radar (what changes every day) and Pregúntale (answers cited to the Biblioteca).

What does it cost?

Nothing. The account is free and opens everything published at opening. If paid courses are offered later, they will be additional, and the Biblioteca will remain free.

Who is it for?

People importing or exporting for the first time; staff at customs brokerages, forwarders, carriers and logistics providers; compliance teams; students; and professionals who need the source at hand.

Can I use COEX Academy instead of a customs broker or a lawyer?

No. COEX Academy teaches and informs; it is not legal advice, nor tax or customs advice. In a specific operation, classification and clearance are the responsibility of the importer or exporter and their customs broker; for a legal opinion, consult a lawyer.

When does it open?

We will open in cohorts. Join the waitlist: we review every request and email the invitation when yours opens.
