Cenvat credit- event for registration?

Dear Friends,

Kindly guide in the following matter related with CENVAT Credit:-

Our Company is a First Stage Dealer and already registered for CENVAT Credit in Utter Pradesh.  Now, we want to expand our business activities outside U.P. and considering establishing factory in Karnataka.  However, we have not yet applied for registration for availing CENVAT Credit in Karnataka.  We are thinking to buy machine from outside of India, which will take around 30 to 45 days to reach in India. If, meanwhile, I apply for the registration for CENVAT Credit at Karnataka, “so will I be able to avail CENVAT Credit before reaching the said machines?”

                                          Or

Registration for CENVAT Credit is required before placing the Order of such Machines?

Kindly answer the aforementioned issues. Your valuable suggestion will be greatly appreciated.

Thanks & Regards,

Harvinder
