CDS Errors
Errors reported by CDS are displayed in Sequoia in the CDS Declaration Errors dialog (as shown below).
This will display one or more Error Messages in a list, and potentially one or more Additional Information details in a list below the error messages.
These errors are generated by the CDS declaration processing application.
Unfortunately the ASM Helpdesk is unable to assist with these errors. We can not advise you how to complete a customs declaration.
