When Customs cancels a transaction, the original transaction remains part of the carnet's history.

The ATA Carnet System maintains a complete audit trail of all customs actions, including cancelled transactions.

Does a cancelled transaction disappear?

No.

A cancelled transaction remains visible in the transaction history so that users and Customs authorities can understand what actions were previously performed on the carnet.

Why do I see what looks like the same transaction twice?

This often happens when:

1. a transaction was committed;
2. Customs later cancelled that transaction; and
3. a corrected transaction was performed afterwards.

The transaction history may therefore show both the cancelled transaction and the replacement transaction.

Does a cancellation mean Customs rejected my carnet?

No.

A transaction cancellation simply means that a previously committed transaction was reversed.

The cancellation may have been performed to correct errors, amend data or allow the transaction to be processed again correctly.

Do I need to prepare a new travel after a cancellation?

In many cases, yes.

Once a committed transaction has been cancelled, Customs may instruct the holder to prepare a corrected declaration and generate new transaction codes before the movement can be processed again.

Who can cancel a transaction?

Transaction cancellations can only be performed by Customs using the cancellation procedures available to Customs officers. Holders cannot cancel customs transactions themselves.
