Section 20. Reservation of Eight of Possession or Property when Goods are Shipped.—

1. Where there is a contract to sell specific goods, or where goods are subsequently appropriated to the contract, the seller may, by the terms of the contract or appropriation, reserve the right of possession or property in the goods until certain conditions have been fulfilled. The right of possession or property may be thus reserved notwithstanding the delivery of the goods to the buyer or to a carrier or other bailee for, the purpose of transmission to the buyer.

2. Where goods are shipped, and by the bill of lading the goods are deliverable to the seller or his agent, or to the order of the seller or of his agent, the seller thereby reserves the property in the goods. But if, except for the form of the bill of lading, the property would have passed to the buyer on shipment of the goods, the seller's property in the goods shall be deemed to be only for the purpose of securing performance by the buyer of his obligations under the contract.

3. Where goods are shipped, and by the bill of lading the goods are deliverable to the order of the buyer or of his agent, but possession of the bill of lading is retained by the seller or his agent, the seller thereby reserves a right to the possession of the goods as against the buyer.

4. Where the seller of goods draws on the buyer for the price and transmits the bill of exchange and bill of lading together to the buyer to secure acceptance or payment of the bill of exchange, the buyer is bound to return the bill of lading if he does not honor the bill of exchange, and if he wrongfully retains the bill of lading he acquires no added right thereby. If, however, the bill of lading provides that the goods are deliverable to the buyer or to the order of the buyer, or is indorsed in blank, or to the buyer by the consignee named therein, one who purchases in good faith, for value, the bill of lading, or goods from the buyer will obtain the property in the goods, although the bill of exchange has not been honored, provided that such purchaser has received delivery of the bill of lading indorsed by the consignee named therein, or of the goods, without notice of the facts making the transfer wrongful.
