Applicability of excise on job work

Dear Sir,

Please give me some information regarding the job work sales valuation.  we were doing job work. in the job work we are receiving raw materials from supplier, and we were taking input excise on job work material received by us.  Now we are sending the material after doing job work what would be the assessble value for paying excise duty?  Ex. We have received 10.000mt @ 53000/- valued Rs.530000/- it is landing cost to us and in this we have taken input excise duty on assessble value of Rs.350000/- Now what is the value to be calculated it is landing cost plus job work charges plus profit or input excise duty assessble value plus job work charges plus profit.  kindly give me your opinion and also give me suggestion about service tax. in the above case we were paying the excise duty on despatch of materials of every despatch. after completing the order of job whether we have to pay service tax on the total order or not? 

It is cost of material supplied plus job charges. Job charges includes the value of minor material used by job worker and his profit margin, hence these things are not required to added separately. While taking the cost of material excise duty amount should not be added if cenvat has been taken.
