Excise duty and vat 2

Respected sir / madam,                                            

 I am dealing in metal scrap trading registered company. when the scrap matierial is imported  in Gujarat the rates of scrap  are increased by paying the ED and VAT. If I sell it in Delhi to manufacturing unit how much ED and VAT can be recovered back from Gujarat state or Central excise authorities.                                            

                                                                                  Can anyone please clarify my query. Thanks in advance for giving me your precious time and advice.  

Ankur.
