TAXATION MANAGEMENT USING ASYCUDA++ Ó UNCTAD - SITE (V1.15) A.20 Customs Tariff Management To   add   or   change   rates   of   taxation   (see   'Inserting   Rates   of   Taxation')   means   individually accessing  each  relevant  Commodity  Code.  This  is  a  time  consuming  process,  particularly  if  you need to insert or alter similar rates across a broad range of Commodity Codes. To  change  the  details  for  a  number  of  Commodity  Codes  using  common  data,  such  as  a  rate  of 20% for Import Customs Duty across an entire Tariff Chapter, you can select and update the rate in that Chapter in one operation, as a block. Other data elements input through the Commodity Code screen can be updated as blocks, in a similar fashion. To add or change taxation over a range of Commodity Codes select:- MODCHQ,  ‘Functions’,  ‘Database  Management’,  ‘Simplified  Management’,  ‘Customs  Tariff’ which displays this screen         Figure A.12: MODCHQ: Functions: Database Management: Simplified Management: Customs Tariff Defining The Tariff Range To make any update by inserting or altering data in a block of Commodity Codes, first specify the Commodity  Code  range.  The  syntax  of  the  "Tariff  ranges<s>"  editing  box  is  simply  explained  as follows - The Tariff Code must be enclosed in square brackets, for example - [8701] - specifies all Commodity Codes within heading 8701. The  Commodity  Code  coverage  is  from  a  two  digit  level  to  eleven  digits;  for  example,  at  Chapter level, like [87], or as specific as the lowest level national subdivision, such as [87011010000]. Tariff  ranges  can  be  used  but  the  syntax  requires  that  the  ranges  be  defined  in  pairs,  using  a comma as a separator, for example - [01, 05]  - selects all ComCodes in Chapters 1 to 5. [5501, 550110] - selects all ComCodes for Heading 5501 up to and including Subheading 550110. Multiple selections can be made, either of ranges or by combining single selections, for example – [01] + [03] + [040210] - selects chapters 1 and 3 and sub-heading 040210. [8501, 8506] + [91] selects all ComCodes for heading 8501 to heading 8506, plus all of chapter 91. Excluding  part  of  the  range  initially  selected  can  further  refine  range  selections.  The  following example illustrates this point, for example - [55] - [5503] selects all the  ComCodes for Chapter 55 except  ComCodes of heading 5503.
