Duty calculation for import PO for a specific material group

Question

Hi All,
As per company requirement, we need to do changes in duty calculation for import PO for a specific material group.
Current scenario :  Currently  duty calculating on MRP with abatement  35% ( We have ABTT condition @ 35% of MRP).
For example:
Material: ABC , Basic Price = 1000, MRP = 2000 and duty is 10%
Duty  Amt = 2000(MRP) - 700(35% ABTT) *10%(Duty) = 130
Cess 2 % = 2.6
Ecess 1 % = 1.3
Total duty =  133.9
This duty (133.9) paid to custom vendor and loads in material cost.
New Requirement:  For vendor payment purpose duty should be calculate as above but  for material cost should be calculated on Basic price.
For Example:    
Material: ABC , Basic Price = 1000, MRP = 2000 and duty is 10%
Duty  Amt = 1000(BP) *10%(Duty) = 100
Cess 2 % = 2
Ecess 1 % = 1
Total duty =  103 ( It should load in Material cost)
New Condition Diff Duty Amt = (1300-1000)*10% = 30
Cess 2 % = .6
Ecess 1 % = .3
Diff Duty Amt = 30.9 ( It should not be added in material Cost)
Paid to custom vendor = 103 + 30.9 = 133.9
Kindly suggest how to achieve this.

Hi,
   Please check whether the requirement is logical or not.  Did you check the requirement with your accounts team?
   If you have different duty calculation for MIGO and MIRO, how the GL accounts will get balanced? As of my understanding, the requirement is clearly not logical.
