Contact the carrier, or your client, for a new commercial release or renewal. The client can also see in his own overview that the commercial release is no longer active or has been given a red status.
Your chain may have already been fully prepared, and this chain is still active at this point. Only without the commercial release your inland operator cannot remove the container. If the carrier resend the commercial exemption, this automatically restores your already prepared chain and your inland operator can submit the pre-notification.
