The buyer has no right. Because CIF is a contract of shipment, according to CIF trade terms, the seller has fulfilled the obligation of delivery by loading the goods at the port of shipment within the specified date. The seller's delivery of the goods on the basis of documents symbolizes sexual intercourse rather than actual delivery. As long as the seller submits and transfers the bill of lading and insurance policy to the buyer, the buyer will pay regardless of whether the goods can reach the destination port or whether they suffer losses on the way. In this case, when we shipped the onion under the CIF contract at the Japanese port, it was verified by the notary office that it was completely in line with the commercial quality and issued a certificate of conformity. However, when the goods arrived in Australia, all the onions were rotten and unfit for human consumption, so the buyer refused to accept the goods and asked the seller to refund the paid money. This is inconsistent with the CIF contract, so the buyer has no right.
