Purchasing from SEZ

Hi,

We need to do purchasing from SEZ and need to pay following duties:

1. Custom (3.75%)

2. Custom Ecess (2%)

3. Custom HEcess (1%)

4. CVD (10%)

5. CVD Ecess (2%)

6. CVD HEcess (1%)

7. Ecess under section 93 (2%)

8. Ecess under section 138 (1%)

and

9. Sales Tax (2%)

The duties paid against CVD (point 4, 5 & 6) are cenvatabale while duties paid against Custom, Ecess (under section 93 & 138) and Sales Tax (point 1, 2, 3, 7, 8 & 9) are to be loaded to Inventory.

Can anyone provide some idea in order to handle this scenario?

Thanks in advance
