HMRC is currently building and testing CDS with industry, software providers and Community System Providers (CSPs). CSPs operate computerised inventory systems that control the physical movement of import and export freight at UK ports and airports.
CDS will be phased in between August and early 2019, with CHIEF continuing to run during this time to aid the transition.
MIES will be in touch with all customers soon as we will need you to provide the additional information in order to start making declarations on CDS also you may need to sign into CDS on GOV.UK through a government gateway account to view declarations and access data etc.
