MODCHQ - SET UP AND MAINTENANCE Ó UNCTAD – SITE (V1.15) 10.17 Customs Procedure Code Structure Customs Procedure Codes are structured using four numerical characters. Starting from the first digit - the highest (or broadest) level - and working down, the four character code  numbers  can  be  constructed  and  linked  to  pre-programmed  System   'Actions',  (such  as procedures for temporary imports or warehousing), or to allow for specific taxation treatments. By using precisely defined   CPCs,  special  taxation  outcomes  can  be  managed  by  writing  individual taxation rules, linked directly to the CPC. (See  ‘Taxation Management’, ‘Appendix B’  for further details.) Model of Declaration ‘Model of Declaration’  is  a  table  that  links  each  General  Procedure  type  to  either  the  import  or export  declaration  model.  The  General  Procedure  types  are  listed  below.  By  using  this  link,  the descriptions  (labels)  on  screen,  and  in  the  printed  declaration,  take  either  an  import  or  export format, according to the selected General Procedure. The ‘Model of Declaration’ screen allows a description of the model type to be defined, for display to users, e.g. IM4 =  “Import Declaration – Entry for Home Use”, and also setting an alphanumeric character as a prefix for identifying the system Reference and Assessment numbering series. (See ‘Section 9’ ‘Customs Office Configuration’, ‘Series Management’ for an explanation on setting up the numbering series.) Using   the   declaration   configuration   function   within    MODCHQCF   separately   sets   the   data requirements for the Import and Export models -‘Functions’, ‘Declaration’, ‘Import Declaration’ or  ‘Export  Declaration’.  This  basic  Import  and  Export  configuration  may  be  modified  by  a  rule included  in  the  Model  of  Declaration  record.  This  means  that  separate  configurations  can  be defined for each type of declaration if required. A field allows the user to capture a rule to define what fields need to be  ‘Mandatory’, ‘Optional’  or ‘Forbidden’.  Only  the  fields  that  you  can  normally  configure  within   MODCHQCF   can   be   re- configured  within  the  rule.  The  configuration  rules  for  these  fields  will  override  those  defined  in MODCHQCF. Here is an example of a rule to modify the configuration of a Model of declaration: Config “DEMO”; Consignee IS Mandatory; Bankcode IS Forbidden; Goods2 IS Optional; Ctl_ExistLocode Is Off; In this example the Consignee field is set to Mandatory and must be captured, the Bank code is Prohibited and the Description of Goods field 2 is Optional. In MODCHQCF, ‘Declaration configuration’, it is also possible to configure a number of controls on or off, such as “ location of goods must exist in the database”. This is the purpose of the final line of the rule above. The <F9> local menu option is available when defining the rule so that the Variables, Functions and Keywords can be checked. The Variable list will show the fields and controls accessible for modification. General Customs Procedure The first numeric character of the CPC signifies the General Procedure Code number. This is an internationally agreed standard:
