On 16th August, HMRC announced that it had successfully implemented the first software release for its new Customs Declaration Service (CDS). It will replace the existing Customs Handling of Import and Export Freight (CHIEF) system over 3 phases between August 2018 and early 2019. Following implementation of the first release of CDS on 14th August, a selected group of importers will start making certain types of supplementary declarations on CDS. The majority of importers will start using CDS from November, once their own software provider or in-house IT team has completed development of CDS-compatible software. Exporters will follow after this. CHIEF will continue to operate in parallel while the transition of traders takes place.
