Guidelines and General Information


1. For the purpose of this memorandum,

cargo container
means a reusable and identifiable article of transport equipment, 6.1 metres or greater in length and having an internal volume of 14 cubic metres or more, classified under tariff item No. 9801.10.20, especially designed to facilitate the carriage of goods by one or more modes of transportation but does not include either a vehicle or conventional packing.

CBSA Post Audit System
means an independent control system exercised by periodic audits of control and accounting documents covering the use of cargo containers that are classified under tariff item No. 9801.10.00 and conditionally imported by container operators or container pool operators approved under the authority of the Deputy Minister.
Deputy Minister

General information

2. These guidelines and procedures apply to cargo containers as defined in paragraph 1 only and do not affect in any way the normal container bank procedures under tariff item numbers. 9813.00.00 and 9814.00.00 for handling containers such as drums, skids, pallets, cores, racks and crates.

3. A cargo container that is employed in the international carriage of goods may be used:

4. Cargo containers used to move cargo into Canada are to bear the name or reporting marks of the owner or lessee and the identification number of the container.

5. Information on the Customs Convention on Containers (1972) can be found in the Appendix of this memorandum.

Documentation and Authorized Use

6. Cargo containers arriving in Canada under the CBSA Post Audit System do not require separate cargo control documents for each cargo container. Control is exercised by means of a Canada Border Services Agency (CBSA) audit of company records.

7. Cargo containers controlled under the CBSA Post Audit System must be exported from Canada within six months of importation.

8. Cargo containers arriving in Canada that are not under the CBSA Post Audit System must be controlled. A list of the cargo containers and their identification marks and numbers along with the cargo control document must be presented to the CBSA. Such containers can only remain in Canada for 365 days.

9. Cargo containers that are or not under post-audit control in Canada may make one domestic move under load en route to a repositioning of the container for export, i.e. between the point of discharge of the imported cargo and the point of loading cargo for export or the CBSA office at the point of exit. This procedure does not apply to a transcontinental or other movement under which a container pool in one part of Canada is merely being supplemented by containers from another pool.

10. In all cases, a cargo container must remain the responsibility of the party under whose control the container is stated to be at time of initial report to the CBSA.

11. Where there is significant evidence that the condition of a container creates an obvious risk to safety, the container may be retained in Canada pending restoration to a safe condition for a period not to exceed 24 months. In such instances, Form E29B, Temporary Admission Permit, is to be issued for the container for a specified period of time that is sufficient to accommodate the stated contingencies and to provide for compliance by exportation. Containers reported under the Customs Post Audit System do not need to be documented on a Form E29B.

CBSA Post Audit System

12. A firm that maintains an inventory of cargo containers for use in international service may be designated as either a post-audit container operator or container pool operator, provided the company maintains records acceptable to the CBSA of all containers under its ownership or control from which the CBSA auditors may determine all movements of such containers in Canada. Applications for post-audit status should be directed to the following program:

Border Information Service
1-800-461-9999. From outside Canada call 204-983-3500 or 506-636-5064. Long distance charges will apply. Agents are available Monday to Friday (08:00 – 16:00 local time / except holidays). TTY is also available within Canada: 1-866-335-3237.

13. Cargo containers arriving in Canada under the ownership or control of post-audit container operators or post-audit container pool operators do not require cargo control documents. When the cargo container with cargo is turned over to a connecting carrier for furtherance to a destination for clearance, the carrier does not need to manifest the container. A reference to the owner or lessee, or the reporting marks, and the identification number of the container in question will be inscribed on the cargo control documents covering the cargo. Subsequent movements of the container in Canada, after the import cargo is discharged, will not be effected under a cargo control document but the CBSA control will be maintained by audits of the records of the container operator and the connecting carriers.

14. The repositioning described in paragraph nine (9) that are under post-audit control in Canada may take place over a route outside the territorial limits of Canada provided the following applies:

15. Under no circumstances may an empty container arriving in Canada be used in domestic point-to-point service.

Criteria for Admittance to the CBSA Post Audit System

16. In order to qualify for admittance to the CBSA Post Audit System, the applicant must:

Audit Trail Requirements

17. During both the initial facilitation audit to determine eligibility and subsequent verification audits, agency auditors will be reviewing company records relating to the reporting of import shipments and, where non-duty paid equipment is used, the use of that equipment in Canada.

18. Consequently, auditors will require access to such records as:

19. All of the documentation required for an audit must be available within the applicant's records. Audits will not be conducted at more than one company to track down any shipment.

20. A post audit carrier is permitted to contract with another carrier to transport goods into Canada on behalf of the post audit carrier. However, the goods must be reported to the CBSA under the post audit carrier's cargo control documents and carrier code. Furthermore, the audit trail for these goods must be maintained in the post audit carrier's books and records.

21. Applicants must maintain an internal system of control over the use of non-duty paid equipment entering Canada in the course of international service, as well as over non-duty paid equipment pick-up on interlines. The system must be able to provide the following information:

22. For additional information on the use of non-duty paid equipment engaged in the international commercial transportation of goods and persons, refer to Memorandum D3-1-5, International Commercial Transportation.


23. Post audit privileges are not transferable and cannot be sold or disposed of through amalgamation or change of ownership.

Penalty Information

24. For information on administrative penalties, please refer to Memorandum D22-1-1, Administrative Monetary Penalty System (AMPS). Information on AMPS penalties is also available on the AMPS Web page.

25. Other administrative sanctions, such as the revocation of program privileges and penalties of other government departments, may also be applicable.

26. In some situations, failure to comply with the CBSA requirements outlined in the Customs Act may result in the seizure and forfeiture of the goods and/or conveyance. In serious cases, criminal charges may be applicable.

8. The beneficiary of approval must affix an approval plate to the approved containers before using the containers to transport goods under CBSA seal.

9. The approval plate has to be affixed permanently and in a clearly visible place adjacent to any other approval plate issued for official purposes.
