Dear Varun Arora Ji,
Query-wise reply is as under:-
1. No. You are to follow the procedure laid down under Notification No.214/86-CE dated 25.3.1986 as amended read with Rule 4(6) of Cenvat Credit Rules, 2004. Since the manufacturer takes the responsibility of discharging Central Excise duty while filing intimation with the jurisdictional A.C./D.C.of the job worker with a copy to the A.C./D.C.( having jurisdiction over the manufacturer who sends the goods for job work), no intimation is required to be submitted again after receipt of the job-worked goods back. You are to make proper entries in the register prescribed for job work for proper accountal of the job-worked goods.
2. No.
3. In case the activity undertaken by the job worker amounts to manufacture (Except Liquor), the responsibility of discharging Central Excise duty is cast upon the principal manufacturer. However, the job-worker may also pay duty on the job-worked goods, in case the said goods are not to be sent back for any other process to the principal manufacturer. It is pertinent to add that primarily principal manufacturer is liable for discharging Central Excise duty. In case the activity undertaken by the job worker does not amount to manufacture, he will pay service tax after availing threshold exemption limit of Rs.ten lakhs.
