Some goods cannot be imported with only an invoice, customs entry and payment of duties. Depending on the tariff code, origin, customs regime and product characteristics, Mexico’s Ministry of Economy or another authority may require a prior authorization. Discovering it after goods ship is one of the most avoidable ways to stop an operation.
Three terms, three different requirements
| Instrument | What it means in practice |
|---|---|
| Prior permit | Authorization that must be obtained before importing or exporting regulated goods. The authority reviews the application under product-specific criteria. |
| Automatic notice | A prior record or notice for certain transactions. It is not the same as a discretionary authorization, but it must be obtained and declared correctly when applicable. |
| Automatic permit | An authorization issued through a specific procedure for certain goods; requirements and validity vary by instrument. |
The requirement is not determined by a product’s commercial name. It comes from its tariff classification and the conditions in the Rules and Criteria on Foreign Trade Matters, particularly Annexes 2.2.1 and 2.2.2.
How to identify the requirement
Before issuing a purchase order, follow this sequence:
- Classify the goods correctly. The tariff code is the starting point.
- Check the current annexes. Confirm whether the code appears in Annex 2.2.1 and which criteria or documents Annex 2.2.2 requires.
- Validate regime and origin. Requirements can change for definitive import, temporary import, Rule 8 or another regime.
- Review other authorities’ rules. A Ministry of Economy permit does not replace sanitary, environmental, safety, NOM or COFEPRIS requirements.
- Apply before shipment. Have VUCEM filings and supporting documents ready early enough to correct observations.
Where importers get caught
Steel products are a familiar example of goods subject to automatic notices. Textiles, apparel and footwear can also have specific requirements, particularly where estimated prices or sector measures are involved. These lists and conditions change, so a prior shipment does not prove that the next one is exempt.
Assess each operation based on its tariff code, technical description and facts—not on the assumption that a supplier has shipped it before.
The mistake that holds cargo
Buying, manufacturing and shipping first; asking about regulations later. When an application needs a final invoice, technical sheet, certificate or supplier information, collecting it at the port can take days. The container waits and charges rise.
Also verify validity, authorized quantity, tariff codes, applicant and invoice details before using any authorization in a customs entry.
Pre-shipment checklist
- Tariff classification reviewed by a specialist.
- Current annexes and applicable rules checked.
- Permit, notice or authorization filed with correct data.
- Supplier invoice and technical documents aligned with the filing.
- Validity and authorized quantity confirmed.
- NOM and labeling and sector registry reviewed where applicable.
