What is an Import/Export Account?
If you are planning to import goods into Canada or export goods to other countries yourself rather than doing it through an agent, you should register an import/export account. The import/export account number is used by the Canada Border Services Agency to identify exporters and importers, and to process customs accounting documentation.
To avoid delays in releasing your goods at the border, you should open your account before you import or export goods.
You have to show your import/export account on your customs documents. This applies to most shipments that enter Canada.
You only use your import/export account for importing or exporting. If you do not use it, your account will expire after two years.
If you will only be either importing OR exporting, you can register just that section of the account.
