CBSA Message (TCC19-113): TCCU Tip

To ensure that Technical Commercial Client Unit (TCCU) officers are available for the resolution of urgent, technical problems, please consult the following frequently asked questions and their respective answers:

1) What does this error code mean?

The CBSA offers a complete list of all Electronic Data Interchange (EDI) error codes and their interpretation at:

2) Why haven't I received a declaration accepted message yet?

The declaration accepted notice is only sent when both the release request and the cargo are on file. Customs brokers will not receive the declaration accepted notice if the ACI cargo has not been reported by the carrier or the freight forwarder.

Check with the other trade chain partners to confirm that all required documents have been accepted by the CBSA.

3) Can you check if the RMD corrector has been processed by the port?

If you are seeking information regarding a paper B3, cash entry or any paper release service option (i.e., ACROSS service options 117, 174, 331) please contact the CBSA office where the request was submitted.  Similarly, any follow up questions on a paper RMD correction should be directed to the CBSA office where the RMD correction was submitted.

4)  What does code 464 or T36 mean (duplicate cargo control numbers)?

No assistance is required from the TCCU to resolve this.

Whether an “invalid status of request/cargo control number” or “ccn in history”, these reject messages mean the cargo control number (CCN) has been used previously.

To correct the reject, a new cargo control number is required from the carrier.

If you need to know where this cargo control was used, contact the carrier.

Alternatively, you or the carrier may transmit a status query through the Release Notification System (RNS) which can provide this information.   For more information on the status query function, please consult the RNS Electronic Commerce Clients Requirements Document (ECCRD).  If needed, you may request a copy of the RNS ECCRD by email at

5) What does a W80 reject code mean?

If you receive reject code “W80 for Release cannot be related to a consolidated cargo or House bill” this mean the cargo control number (CCN) quoted on your release entry is either a consolidated cargo or a consolidated House Bill. 

To correct the reject, you must contact the carrier and confirm with them if the CCN is consolidated.  If it is consolidated, you will need to obtain a new CCN and correct your transaction with the proper CCN.   If it is not consolidated, the carrier may contact the TCCU to follow up if necessary.

6) What does this Canadian Food Inspection Agency (CFIA) reject message mean?

A reject message on your release transaction with error code 537 or 4B9, and with text beginning with “CFIA” was created by CFIA.

If you need assistance in troubleshooting the reject, please contact the National Import Service Central (NISC) at 1-800-835-4486 or 1-905-795-7834.
