TAXATION MANAGEMENT USING ASYCUDA++ Ó UNCTAD - SITE (V1.15) A.12 Valuation Rules are input through MODCHQCF. The normal Customs Import and export valuation and apportionment rules are predefined within your system and so no modification of these Rules should be required. The Rules are fully user definable to take account of any national requirements. Figure A.5: MODCHQCF: Functions: Taxation Standards: Import Valuation Note Rule selection options are available under both 'Export Valuation Note' and 'Import Valuation Note'. The Rule selection window gives you the option to define ·     General segment or declaration header valuation rule. ·     Item section rule. ·     Value apportionment rule. ·     Mass apportionment rule. ·     Rule (any other method of apportionment). Selection of Apportionment Method After  apportionment  Rules  have  been  defined,  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. Choice of method is available under <F9> Local Menu options. General Segment Note Under   the   General   Segment   Note,   a   Rule   (similar   to   the   predefined   Rule   below)   takes   the declaration  data  that  has  been  input  and  calculates  the  invoice  value,  freight,  insurance,  other charges and deductions by converting into national currency.  The Rule is structured as a series of statements   that   assign   values   to   variables,   and   those   variables   are   in   turn   used   for   other processing by the system. A list of variables used by Valuation Note Rules is shown later in this Appendix. Figure A.6: MODCHQCF: Finctions: Taxtion Standard: Import Valuation Note
