Document Category - 

The First Component: Identifies the class or kind of document being declared.

The first component (a1) consists of a letter and is used to distinguish between the three categories mentioned below:

● the declaration for temporary storage represented by ‘X’

● the simplified declaration or the entry in the declarant’s records, represented by ‘Y’

● the previous document, represented by ‘Z’.

For example: Y (to represent simplified procedures).

Previous Document Type - 

The Second Component (an..3), consists of a combination of digits and/ or letters, serves to identify the type of document:

For example, code: CLE (to represent the entry in declarant’s records) or EU and ECS.

DMS uses the CodeList ExportPreviousDocuments for these items. (Note: For this CodeList please refer to CDS 03 CDS Codelists and WCO References ).

Previous Document Reference - 

The Third Component (an..35) represents the data needed to recognise and identify the document.

● The identification number or another recognisable reference of the document

For example, 20171001 (to represent the date of the entry in records).

Expected format for a DUCR (i.e. when TypeCode equals 'DCR'): [0-9][A-Z][A-Z][0-9A-Z\(\)\-/]{6,32} All alphas used must be upper case - First character to be a number - Second and Third character to be alpha (upper case only) - 16th digit to be a hyphen - Post the hyphen any character is allowed but any alphas must be upper case

Expected format for a MUCR (i.e. when TypeCode equals 'MCR'): |GB/[0-9A-Z]{3,4}-[0-9A-Z]{5,28}|GB/[0-9A-Z]{9,12}-[0-9A-Z]{1,23}|A:[0-9A-Z]{3}[0-9]{8}|C:[A-Z]{3}[0-9A-Z]{3,30} All alphas used must be upper case - First character to be an alpha character
