Bill of entry correction

Dear Sir,

We have imported a cosignment whose amount in invoice indicates currency as Yuan. However Fedex has cleared the subject consignment with BOE made in INR currency. This has lead to payment of reduced amount of taxes and the consignment has finally cleared.

However we would like to get the BOE corrected to Yuan and are willing to pay the extra taxes due. However FedEx is refusing to correct the BOE stating that it cannot be done. Please suggest the way out.
