Preparing to make CDS declarations

Sequoia v5.0 onwards

Upgrading to Sequoia version 5.0 or greater is not the only thing you need to do to access CDS declarations, although it's certainly a part of it.

Before authorising Sequoia to send declarations on your behalf

Before you can connect to CDS there are certain pre-requisite tasks that must be undertaken:

  • All parties (declarants and importers/exporters) involved need to register with CDS using their Government Gateway account to access VAT certificates, deferment account reports, tools, etc.
  • All parties (declarants and importers) need to put in place a new Direct Debit Instruction if they have a Duty Deferment Account.
  • The mobile phone number associated to your Government Gateway account must be accessible as this will be required for two-factor authentication.
  • You will need to use Chrome, Edge or Firefox to connect to the application, it is not compatible with Internet Explorer.
  • We need you to grant access to the following domain names so that they are not blocked by your firewall:

  • It is not necessary for everyone to exit Sequoia while the authentication process is being undertaken. However once the authentication has been completed then each user will need to restart their Sequoia application for the changes to take effect.

  • If you are moving to the new XML API for NCTS then you must complete all movements before the switchover. Any movements that are not completed prior to the switchover will need to be completed manually by contacting NCTS directly.

Duty deferment account

If you have a duty deferment account, you will have to set up a new direct debit to take account of revenue that you defer against CDS declarations.

This is also the case if your customers have their own deferment accounts that you use on their behalf. They will have to set up a new direct debit as well so that you can use their account for CDS declarations.

Your existing direct debit instruction should not be cancelled however. Revenue due from CHIEF declarations will still be taken against that instruction.

More information regarding setting up a new direct debit instruction can be found here.

Creating a new ASM Online account for NTCS and TDR

You will receive an email inviting you to sign up to the new the NCTS (CTC) and TDR platform. The person creating this account must also have access to the Government Gateway account, as signing into the Government Gateway will a part of this process, when you eventually move over to CTC.

When you click on the link in the email you will be taken to the new account creation page where you will be prompted to enter your details.
