Excise duty paid on purchase for input of service tax

Dear all,

We are into a trading ( glass bottle ) line, we are getting excise purchase bills.  shall we adjust ( take credit ) the excise part in our purchase bills for  our service tax payment  on our transport ( as a service reciver ) cost. ( carrying  glass bottles ).

and we have plastick packing grades for carrying glass bottles, those purchase invoice also has excise duty, is it possble to take credit these exice duty for our service tax payment for transport exp.

Also, What is the abatement % for the transport service reciver ?

Thanks
