A receipt of commodities deposited in a warehouse, identifying the commodities deposited. It is non-negotiable if permitting delivery only to a specified person or firm, but it is negotiable if made out to the order of a person or firm or to a bearer. Endorsement (without endorsement if made out to bearer) and delivery of a negotiable warehouse receipt service to transfer the property covered by the receipt serves to transfer the property covered by the receipt. Warehouse receipts are common documents in international banking and trade.
