Commodity Depository
A separate demat account is required for holding warehouse receipts. The securities demat account cannot be used for commodity purpose. Individuals, partnerships firms, companies, etc can open the Commodity Depository account. The contents of the agreement and the charges for Commodities demat account differ from that of securities demat account. Depository Participant must be empanelled by commodity exchanges. Commodities depository account can be availed at both the Depositories i.e. NSDL and CDSL The Commodity Identifier i.e. C-Id is akin to the ISIN Procedure for giving delivery of warehouse receipts is similar to securities transfers by using Delivery Instruction Slips (DIS) and quoting C-Id in place of ISIN.
The Commodities Depository account may be credited in the following situations:
Demat Revalidation Actual purchase from market.
Demat :
If the customer has some commodities with him, he may unload it in the warehouse and take the warehouse receipt after due verification of the Assayer appointed by NCDEX and MCX. To convert the warehouse receipt in demat form, he has to fill up necessary details in the Commodity Deposit Form available in the Warehouse. The Warehouse shall inform the Registrar and Transfer Agents (RTA) with the required details who shall then arrange to credit the depository account of the customer through NSDL/CDSL. Currently, there is only one RTA for commodities i.e. Karvy
Revalidation :
If the client does not wish to open a demat account for commodities then he may trade directly in the market with the physical warehouse receipts (in MCX and NMC) Normally the warehouse receipt (whether demat or physical) is for duration of three months. After three months the receipt owner has to request the Warehouse to revalidate the receipt. The Assayer will examine the commodity and take into account the wear and tear (normal as well as abnormal) for revalidating the warehouse receipt.
