Excise treatment on inter branch transaction of rm and fg

Excise on transfer of RM from Branch Office ( Dealer id) to manufacturing unit of same company (manufacturing Id) and reverse on FG

Actually I am manufacturing PVC Pipes in New Delhi and selling my goods to a dealers in Uttar Pradesh on via retail invoice after leving Cenvat on Cform basis

To avoid paying 2% cst which is cost of my dealer and to avoid claiming refund from Delhi VAT departmant ( as all our purchase is Local) We are planning to open a branch office in UP.

I want to make purchase in UP and transfer the RM to delhi office (factory) and then after producing the goods we want want to transfer the FG to UP office to be sold as local sale

For Vat purpose we propose to send goods on Form F and for cenvat purpose we would like to pay the excise at Delhi production facility

Is it a viable proposition......need an informed suggestion asap

thanks
