Export Procedures

National Export System (NES) and authorisation procedures: full pre-entry declaration procedures

The full pre-entry declaration procedure operates at the UK frontier or at a Designated Export Place (DEP). It is required for certain controlled goods, but may be used for any goods. Declarations must be made electronically under the UCC. Although in rare and exceptional cases - for example for merchandise carried in baggage - customs may manually input your declaration, which will be submitted to the National Clearance Hub (NCH) for processing to CHIEF. This is known as a Customs Input Entry (CIE). Clearance of CIE declarations will take longer to process than other export entries.
