Excise duty on non cenvat material purchased

Dear Experts,

We are a manufacturing unit. We purchsed some die from party and seller send us a non cenvatable bill because he have not excise registration but we are selling these dies. So my question is can we sell die without excise or we make an invoice acc. to rule no 11 of central excise with excise duty. 

Thanks & Regards,
