Integrated logistics giant Maersk has notified customers that the UK’s new Trader Support Service (TSS) platform officially went live on October 20, 2026.
Moving forward, all goods shipped between Great Britain and Northern Ireland must be submitted through the upgraded TSS platform. Despite the transition, HM Revenue and Customs (HMRC) confirmed that underlying customs procedures and legal requirements for businesses remain unchanged—only the platform interface and access protocols have been updated.
Maersk highlighted that while the previous TSS system no longer accepts entries for new goods movements, it will remain accessible until November 30, 2026, for two specific tasks:
- Closing Outstanding Supplementary Declarations: Declarations remain incomplete until their status is explicitly marked as “Closed.” Maersk strongly advises traders to audit open declarations and resolve any outstanding issues immediately.
- Downloading Historical Records: Businesses can archive their previous declaration records. Beyond the portal, historical data can also be requested via HMRC’s Trade Reporting and Extracting Service.
Full access to the old TSS environment will terminate permanently after November 30.
Urgent Action Required for Shippers
To prevent potential supply chain delays or disruptions to goods moving into Northern Ireland, Maersk urges businesses to verify their enrollment on the new platform as soon as possible.
Traders should immediately review and confirm:
- Company profiles and registered user access
- Customs authorizations, including UK Internal Market Scheme (UKIMS) status
- Authorized agent relationships
For further details on setup and account validation, shippers are advised to log into the new TSS portal or consult HMRC guidance.
