Why is only one VIN allowed per transaction when the IID structure accommodates up to 999 different commodities on one entry?

The following TC Vehicles Programs are restricted to a single VIN per SWI IID submission. To avoid delays for clients registering their vehicles, CBSA has implemented a new validation rule which will trigger a reject if the IID contains more than one VIN number. This rule applies to the following Vehicles Programs:

  • CMVSS Case-By-Case (B9.5.1)
  • FMVSS Standard (B9.6.1)
  • FMVSS Case-By-Case (B9.7.1)
  • Vehicles for Parts (B9.11.1)

The TC Vehicles Programs listed below allow for multiple VINs, but are restricted to one VIN per commodity line, and all regulated commodities must be reported on the same invoice:

  • CMVSS Appendix G (B9.4.1)
  • Age Exemption (Greater than 15 Years) (B9.8.1)
  • CMVSS Returning Vehicles (9.9.1)
  • Unregulated Vehicles (B9.10.1)

Please note that the above restrictions do not apply to the CMVSS Appendix F program.
