Preservation of identity of goods

Every warehouseman shall keep the goods of one depositor separate from the goods of other depositors and from other goods of the same depositor for which a separate receipt has been issued, in such a manner as to permit at all times the identification and delivery of the goods deposited : Provided that where standardised and graded goods are stored in a warehouse, then, subject to any agreement between the warehouseman and a depositor, the same variety of goods belonging to different depositors may be stored together and each depositor shall be entitled only to his portion of the goods according to weight or quantity, as the case may be, as shown in his receipt.
