Under a term "no arrival, no sale" or terms of like meaning, unless otherwise agreed:
(a) the seller must properly ship conforming goods and if they arrive by any means the seller must tender them on arrival but the seller assumes no obligation that the goods will arrive unless the seller has caused the nonarrival; and
(b) where without fault of the seller the goods are in part lost or have so deteriorated as no longer to conform to the contract or arrive after the contract time, the buyer may proceed as if there has been casualty to identified goods ( 30-2-613).
