HM Revenue & Customs (HMRC) is currently experiencing technical difficulties with the Customs Declaration Service (CDS). To minimise disruption, HMRC has implemented contingency processes to allow businesses to continue moving goods and freight while full service is restored. 

Contingency Measures in Place 

  • Hauliers using the Goods Vehicle Movement Service should create a Goods Movement Reference (GMR) and select ‘Declaration by Conduct’ 
  • At maritime Temporary Storage locations, carriers and shipping agents are authorised to use contingency manifest codes (such as ‘C’ or ‘T2’ status, depending on the inventory system in use). 


Traders should use these options wherever possible. If they are unable to do so, they should contact the CDS helpdesk and provide their unique consignment number (UCN) and, if available, the Movement Reference Number (MRN). 


The C130 form will not be required when goods are held at an inventory-linked Temporary Storage location. 


HMRC has acknowledged customer concerns and reiterated its commitment to system resilience. The organisation continues to work closely with stakeholders to minimise disruption and apologises for any inconvenience caused. 


For the latest updates on CDS service availability, businesses are encouraged to consult the official page: Customs Declaration Service: service availability and issues – GOV.UK before commencing any journey.
