Import Process without BCD value

Dear All,

Normally in an Import scenario,7 duties will be there(CVD,ECessCVD,Hig EcessCVD,BCD,EcessBCD,Hig EcessBCD,Spl Addl duty).

We fill the 7 values while doing Customs MIRO and the MIRO number will be given while doing MIGO which adopt the values and posted.

Our Client has faced a problem that,BCD is not there.But ECessBCD and Hig ECessBCD are there which might be calculated from the Assesible vlue too.

But when Customs MIRO (without BCD) is entered,only 6 values(CVD,ECessCVD,Hig EcessCVD,EcessBCD,Hig EcessBCD,Spl Addl duty appear)

When this MIRO number entered and posted in MIGO,the Customs value for the EcessBCD,HigEcssBCD,Spl Addl duty values gets differed.

How to go with this?

Regards
