Duties in Import Process

Dear Guru's,

I had following doubts abt import duties so please help me.

1) How we take care of CVD and other duties in case of import process, how we can define the GL account for the duties in case of import

2) How we can take care of additional CVD

2) at our place for same material sometimes CVD get inventorised sometimes modvatable though it is always modvatable....how can we control this.

we had defined in Excise defaults all the CVD conditions for TAXINN procedure still above problem is there due to which moving average price is shooting up very rapidly.

regards,

Umesh
