Dear Shivaraj,
You would have to get CT-1 form from the Jurisdictional Commissioner/Deputy Commissioner/Asstt. Commissioner as the case may be after executing the General Bond along-with Surety/security and handed over this CT-1 to your supplier with duly signed ARE-1 form to the supplier of the Raw material. Supplier would submit a copy of the CT-1 to their jurisdictional Central Excise Department.
Material may directly be shipped to the port by the supplier as per your instruction along with the supplier's excise invoice and duly filled ARE-1. After that you may raise your export invoice and packing list.
On the Shipping Bill you would have to incorporate the name of the manufacturer/supplier. You would have to file the proof of export and duly acknowledged copy of the same would be provided to the supplier for his future use.
