Your truck did not cross, or it crossed and the goods were held. Every hour costs money. This guide explains, in order, what to do when a commercial shipment is held by Mexican customs in Nuevo Laredo or by U.S. customs in Laredo, and what we check first.

The first steps

  1. Get the reason in writing. The customs report, the hold notice or the system message. Without the exact reason, everything else is guessing.
  2. Pull the full file together. Invoice, packing list, pedimento or entry, Carta Porte, permits and certification of origin.
  3. Do not send corrections one at a time. An incomplete answer makes the hold longer. Understand the problem first, then answer once.
  4. Write down the dates. Deadlines to respond run from the notice.

If the hold is on the Mexican side

The most common causes after a customs inspection are: a wrong tariff classification, a missing permit or NOM, quantity or description differences against the invoice, a declared value the authority questions, a suspended importer registration, and Carta Porte errors. When the authority finds an irregularity it can issue a report and open an administrative procedure (PAMA) with seizure of the goods; the law then gives a short period to present evidence and arguments, so it pays to act the same day.

If the hold is on the U.S. side

U.S. Customs and Border Protection (CBP) can hold a shipment for a document review, an X-ray exam or a physical exam. Other agencies can hold it too: FDA for food, drugs and medical devices, USDA for agricultural products, and others depending on the product. What helps most is a fast answer with the exact document the agency asks for and a clear description of the goods.

So it does not happen again

Most holds start in the paperwork, before the truck leaves. That is why we check the documents before every truck is dispatched. Run the one-minute document check yourself. If your operation crosses every week, see how to switch customs brokers in 30 days and today’s bridge wait times.
