MODSEL - SELECTIVITY MANAGEMENT IN ASYCUDA++ Ó UNCTAD - SITE (V1.15) 6.12 Benefits of Using Lists Using lists within local criteria is, in most cases, a simpler and more reliable way of setting selection criteria.  In  situations  where  you  have  frequent  changes,  where  you  may  be  adding  or  deleting codes from a criteria on a daily basis, the use of a list means that you don’t have to go to the criteria to change the selections. In many cases you may wish to select a wide range of commodity for a particular purpose, or have a  large  group  of  declarants  or  companies  receive  a  particular  Customs  treatment.  Using  a  list allows you to separate your lists from the programming language, which greatly simplifies selectivity control in the Customs office. Using Values as a basis for Selection Declarations can be selected by Customs according to a very wide range of criteria. However, the value of the goods declared to Customs is one of the most important factors. The undervaluation of goods  to  evade  payment  of  Customs  duties  and  taxes  is  of  great  concern  to  many  Customs administrations. As described in the previous section, value comparisons can be built into selection criteria and used to  ‘select’  transactions  when  calculated  values  do  not  fall  within  certain  predetermined  value parameters.   “Example  3”  above  is  a  good  case.  In  this  instance  the  unit  value  of  the  tractor  is calculated and compared to the ‘acceptable’ value of 3000 currency units per tractor to determine if the declaration is to be selected. The valuation controls within  MODSEL are an extension of this ‘calculate and compare’ process. These  controls  are  designed  to  simplify  value  comparisons  and  to  manage  large  amounts  of valuation data linked to CommCods. Value Controls Value controls are managed through the Value Control File. Value control file The Value Control File contains individual records on specific commodities. The  possibility  to  be  ‘specific’  varies  according  to  the  commodity.  In  some cases,   such   as   bulk   products,   comparison   at   CommCod   level   can   be appropriate;   in   the   case   of   others   there   may   be   such   diversity   within   a CommCod that a much more precise definition may be necessary for any value comparison to be useful or valid. Selecting  the  menu  option  ‘Functions’, ‘Value control management’, Value control file’  opens  the Valuation control window. This displays a table of Valuation control records. Records are arranged in columns that are headed: Commodity code Tariff specification Country Formula Description The  window  controls  allow  the  creation  of  new  records  and  the  updating  and  deletion  of  existing records. (Also the normal print and search options.) Creating a Value Control Record Selecting ‘Update’ or  ‘Create’ from the Valuation control window opens the Valuation Control form. The following screen print is an example of a Valuation control form:
