Excise Billing

Hi!!

We have excise unit where our product A & B has been registered under excise. My Questions are;

(1) Is it compulsory that we can only produce and remove product A & B from our excisable unit only?

(2) If we produce & remove product c (non excisable item) from our excisable unit, what will be consequences?

(3) If point 2 is not possible, then can we bill for this product from our office address and in consignee details, can we show end user name and address?

Please help in the above matters. I will be highly obliged.

Thanks & Regards,

Maurya
