MODCHQCF - NATIONAL CONFIGURATION Ó UNCTAD - SITE (V1.15) 8.17 In this case the rule first tests if the preference code is for the EU and that the declared country of origin  is  eligible  for  ‘EU’  preference.  If  the  preference  code  is  ‘EU’,  it  then  defines  two  temporary variables for the Rate and the Duty amount. It then tests to check if the rate in the tariff is greater than 0, if it is, it charges the duty using the RelTax option.  This allows the statistics on loss of revenue to be calculated. The relevant line is as follows. Action IS RelTax( "ID" , "EU" , CustValue ,  Num01 , Num02 ); The meaning of this line is ‘calculate the duty otherwise due under the ID line of the tariff, but do not charge it.  Instead, charge the rate in the EU line and store the loss of revenue under EU’. If however the rate in the EU column were 0 the rule would use the line. Action IS RelTax( "ID" , "EU" , CustValue , 0   , 0 ); This would perform the same revenue loss storage but would actually charge duty at the 0 rate. Action IS AddAttDoc( "861" ); Adds an attached document code in box 44 saying that document 861 is required for this relief. Saving New Rules is done in the same way as for  Global Taxation Rules. Valuation Notes There are two options on the menu - ‘Export valuation note’ and ‘Import valuation note’. These functions allow you to define the rules for calculating the customs value and the method by which the apportionment of freight, insurance, and other charges are applied when processing an export  or  import  declaration.  (The  method  of  apportionment  to  be  used  on  a  particular  declaration can be chosen at the data input stage when the operator is in the Valuation Note screen.) The actual make up of the different forms of apportionment however are defined under the options of this module. The 'Valuation Note' options have sub-menus that give the choices: 1. General segment section 2. Item section 3. Value apportionment rule 4. Mass apportionment rule. This area of the system is extremely powerful and great care should be taken  when  inserting  a  new  column  or  deleting  an  old  one  from  your Tariff.    It  is  essential  that  a  backup  be  taken  prior  to  any  work  in  this area of the system. The normal Customs Valuation and apportionment rules are predefined,  (i.e.  installed  by  UNCTAD),  within  your  system  and  so  no modification of these rules should be required.  The rules however are fully user definable to take account of any national requirements.
