Changes to TSS

Make sure you take the necessary steps prior to the Trader Support Service moving to a new platform on 20th October

Changes to TSS: What you need to do

The Trader Support Service (TSS), which supports the movement of goods between GB-NI, is moving to a new platform and provider on 20th October.  To help businesses prepare for this transition, the latest TSS bulletin has provided the following steps which businesses should be taking in advance of the upcoming deadline.

Steps to take in TSS

  • Check your Company Profile in the outgoing TSS and make sure the following information is accurate and up-to-date ahead of its migration to the new TSS:
      • Company details such as business addresses and EORI numbers
      • Primary user information
      • The list of existing users, including deactivating accounts that are no longer required
      • Contact information, including valid email addresses
      • Authorisations such as UK Internal Market Scheme (UKIMS), Northern Ireland Retail Movement Scheme (NIRMS) and Simplified Customs Declaration Processes (SCDP)
      • UKIMS and Trader Goods Profile (TGP) access permissions
      • Agent and intermediary relationships
      • Payment information
  • Access and secure your data: assess the documents and information held on the outgoing TSS. Access will end on the 30 November 2026, so download any information you need before this date.

Key dates to consider

As well as providing the above information, the latest TSS Bulletin also provides a timeline of key deadlines which businesses need to follow if they are moving goods on, or around, 20th October.

  • You will be unable to pre-lodge declarations on the outgoing TSS for goods movements with an arrival date on or after 20 October 2026
  • For goods movements with arrival dates on or after 20 October 2026, you must submit declarations through the new TSS only
  • Access to the outgoing TSS will end on the 30 November 2026. You should download any information you need before this date
