Why Can Your Cargo Be Held?

Written By Alan Castellanos

The customs inspection process in Mexico—known as reconocimiento aduanero—is one of the most critical stages in customs clearance. Its purpose is to verify that the goods entering or leaving the country match what was declared in the customs entry (pedimento) and that they comply with all applicable tax and trade regulations.

When does a customs inspection take place?

Every shipment arriving at Mexican customs goes through an automated selection system, commonly referred to as the “traffic light system”:

  • Green light → the cargo is released without further inspection.

  • Red light → the shipment must undergo a customs inspection for a detailed review.

Who performs the inspection?

The inspection is carried out by officials from the National Customs Agency of Mexico (ANAM). These officers physically examine the cargo, review documentation, and confirm compliance with Mexican customs law and trade regulations.

What is reviewed during customs inspection?

  • Quantity, weight, and volume of the goods.

  • Tariff classification and declared customs value.

  • Compliance with non-tariff regulations, such as import permits, labeling standards, or product certifications.

  • Commercial invoices and shipping documents.

Why can your cargo be detained?

Several issues may cause shipments to be held at customs:

  • Inaccurate or incomplete customs declarations.

  • Discrepancies in value, weight, or quantity.

  • Missing import permits or certificates.

  • Errors in invoices or transportation documents.

  • Suspicion of undervaluation, smuggling, or fraud.

When this happens, companies may face delays, storage fees, penalties, or even seizure of their cargo.

Why is customs inspection important?

Although inspections can cause delays, they are essential to:

  • Ensure compliance with the Mexican Customs Law.

  • Protect national security and public safety.

  • Prevent fraudulent practices, such as misdeclaration or tax evasion.
