Question: Dealer in the United States owned a cargo of 10,000 barrels of oil that had been shipped from Mexico on January 1 for arrival in the United States on February 1. On January 15, Dealer informed Buyer that the oil was en route and they concluded a contract. On arrival, inspection showed that the oil had been contaminated by seawater at some indeterminate time during the voyage. Assuming the CISG applies, who bears the risk?
