Dear Suresh,
It is clear from your query that you are manufacturing excisable Products and Sending to your Warehouse and in warehouse, packaging is being done and the same price is being adopted at which duty was paid at the time of removal from your factory premises.
In this scenario neither Rule 7 nor Rule 8 of the C.E. Valuation Rules applicable as you are removing goods from warehouse but there is no price variation and goods are not even transferred to your other unit for further manufacturing. Principle of payment of duty on the basis of nearest point of time as applicable in goods sold at higher price from the depots would not applicable in this matter. Please read the both Rules for better understanding.
Hence, in our view after going through the factual and legal position, no need to obtain CAS 4 from Cost Accountant. You may further have discussion with the concerned authority by referring our views in this matter and discuss with us if the Department have any other view to substantiate the need of CAS-4.
We remain.
