The Customs Declaration Service (CDS) is the UK’s single customs platform to complete customs declarations. CDS is replacing the existing Customs Handling of Import and Export Freight (CHIEF) system for goods movements to NI. CDS offers several new services, alongside existing services, all in one place. If you currently use CHIEF for your declarations, youll find that the Customs Declaration Service captures some information differently and the way you input data is different.
Visit the CDS toolkit for details.
