If you are exporting goods from Canada to Mexico for the first time, chances are that you have heard about the B3A. In this post, we explain everything you need to know about the export declaration and keep you up-to-date on the new regulations concerning this form.

Exporting goods from Canada to Mexico

One of the most common questions first-time shippers ask us when planning to ship goods from Canada to Mexico is: Do I need to hire a customs broker?

Here  is a breakdown of the answer:


On the one hand, if you are a Canadian shipper that intends to send goods to Mexico,  you don’t need to hire a customs broker. However, you need to report to the Canadian Government that you are exporting.

The Canada Border Services Agency (CBSA) requires you to declare all goods that require an Export Declaration prior to leaving Canada.

On the other hand,  you need to make sure that the  company importing  the goods in Mexico  complies with the following:

  • Is registered as an importer for the goods that they want to import to  Mexico.
  •  Has a Mexican customs broker who pulls information and documents together to clear the goods through customs in Mexico.


Shipments being transported from Canada to Mexico through the United States and that are not intended to be commercialized in the U.S., are called in-bond loads and they do not clear customs in the US border.

The Canadian Export Declaration (B13A form)

As stated earlier,  if you are a Canadian exporter shipping goods to Mexico,  you must declare all goods that require an Export Declaration prior to leaving Canada.

Export Declaration Timeframes

According to the CBSA, Export Declaration timeframes depend on the shipping mode:

  • Air: 2 hours before the goods are loaded onto the aircraft
  • Marine: 48 hours before the goods are loaded onto the vessel
  • Rail: 2 hours before the goods are loaded onto the railcar
  • Mail: 2 hours before the goods are delivered to the post office
  • Highway: Immediately before leaving the country
