ESReview my operation

Imports and exports · since 2010

When an operation gets stuck, every day counts.

Goods held at customs, a missing permit or a suspended importer registry: we review your case and tell you what is happening and what the next step is.

Review my operation I’m just starting to import

Lic. Leticia AcostaFounder of MexPyme

Why it gets stuck

It almost always starts with something small.

A detail, a label or a document. What makes it big is the time that passes without dealing with it.

  • A wrong detail on the invoice or the value

    A vague description, a quantity that doesn't add up or a value the authorities question.

  • A label without the NOM

    The goods arrive without the commercial information the Mexican standard (NOM) requires.

  • A missing permit

    A notice or permit from another agency that wasn't filed in time.

  • A suspended importer registry

    In 2026 suspensions of the Padrón de Importadores increased and new grounds were added.

  • Supplier documents

    The certificate of origin is missing or the invoice doesn't match what arrived.

  • Red light with findings

    The customs inspection finds differences from what was declared.

Importer registry: Forvis Mazars, September 1, 2026; General Foreign Trade Rules (Reglas Generales de Comercio Exterior) 2026, rule 1.3.3, sections XLIX and L.

Every day counts

The law sets deadlines, and it pays to know them.

Knowing where you stand lets you decide calmly. These are the most common deadlines when an operation is held up.

If your goods are in storage under customs control

The count starts when the warehouse receives them. In sea freight, abandonment counts from the end of the unloading.

  1. Day 0

    Goods enter storage

    This is where the count starts.

  2. 2 days

    Free storage for imports

    After that, storage is charged.

  3. 7 days

    Free storage at sea customs

    For exports it is 15 days.

  4. 2 months

    Goods may be deemed abandoned to the Treasury

    For imports. When it expires, the authorities notify you and you have 15 days to remove them; otherwise they become property of the Treasury. For exports it is 3 months.

If you were served an official notice (acta)

The count starts the day after the service of the notice takes effect.

  1. Day 0

    You are served the acta

    For example, a precautionary seizure or a labeling NOM.

  2. 10 business days

    To submit evidence and arguments

    In the customs administrative proceeding (PAMA, its Spanish acronym).

  3. 30 days

    To prove NOM labeling compliance

    Since 2026 it can no longer be done at your premises: the goods stay held in the meantime.

If your case already has a date, reviewing it soon leaves more room to act. Review my operation

The exact deadlines depend on the customs regime, the goods and the date of each notice.

How we work

What we do when a case comes in.

First we understand what happened. Then we explain the options and coordinate the next steps with you.

  1. Step 1: We review documents and status

    Invoice, air waybill or BL, customs entry (pedimento) and anything the authorities have served you. We find out where your operation stands.

  2. Step 2: We explain what is happening and what the options are

    In plain words: what stopped it, which paths there are and what each one involves.

  3. Step 3: We coordinate the next steps

    With the customs broker and before the authorities: documents, permits, clarifications and whatever your case needs.

  4. Step 4: Document closing

    We leave your file in order and tell you what to watch in your next operation.

What doesn’t depend on us, we don’t promise.

The release of the goods and the resolution times are decided by the authorities. Our job is to make sure you know where you stand, that your case is well presented, and to support you at every step.

Clearance on behalf of another person is carried out by a licensed customs broker or customs agency (Mexican Customs Law (Ley Aduanera), art. 159). We manage your customs clearance with allied licensed customs brokers, according to your case, and coordinate it with you.

Just starting?

Your first import, in five steps.

If you’re about to import for the first time, doing it in order helps avoid surprises at customs and in the cost.

  1. Step 1: Valid RFC and e.firma

    Your Mexican tax ID and SAT e-signature are the basis of any filing with the SAT (Mexican tax authority).

  2. Step 2: Importer registry

    The SAT registry for importing (Padrón de Importadores). Some products also require the sector registry.

  3. Step 3: Tariff code, NOM and permits

    Defined before buying: the tariff code determines the duties, standards and permits.

  4. Step 4: Total landed cost

    Product, freight, insurance, taxes and duties, including the 2026 duties on countries without a trade agreement.

  5. Step 5: Freight and clearance

    We choose the route and coordinate your customs clearance until the goods reach destination.

2026 import duties

5 to 50 %

Since January 1, 2026, about 1,463 tariff codes pay a duty in that range if they come from countries without a trade agreement with Mexico, such as China, India or Korea. The exact duty depends on the tariff code and the origin.

What’s coming

January 15, 2027

The Electronic Value Declaration (Manifestación de Valor Electrónica) is expected to become mandatory for definitive imports as of that date.

Tell us what you want to import and we’ll tell you where to start.
