Which of the following statements is true about contracts on the sale of goods?

1) The substantial performance doctrine is applied to the international sale of goods.
2) The buyer must generally give notice to the seller of any defect in the goods and then allow the seller a reasonable time to cure the defect.
3) If the goods or tender of delivery fail to conform to the contract in any respect, the buyer cannot accept or reject any number of units he chooses to.
4) According to the United Nations Convention on the International Sale of Goods (CISG), the failure to deliver goods is sufficient to show an exception to the perfect tender rule.

The correct answer is 2) The buyer must generally give notice to the seller of any defect in the goods and then allow the seller a reasonable time to cure the defect. The true statement about contracts on the sale of goods is that the buyer is typically required to notify the seller of any defects and allow time for cure. This is consistent with the principles of the CISG, which seeks to encourage good faith and fairness in international transactions.

The statement that is true about contracts on the sale of goods is: The buyer must generally give notice to the seller of any defect in the goods and then allow the seller a reasonable time to cure the defect. In terms of the United Nations Convention on the International Sale of Goods (CISG), it establishes that buyers may be obliged to notify the seller of any non-conformity within a reasonable period after they have discovered it.

This reflects the principles of good faith and fairness in international trade, and it provides the seller with an opportunity to fix any issues, which might prevent costly litigation and preserve the business relationship. Moreover, some aspects of the sales contract, such as substantial performance and the perfect tender rule, can vary depending on the specific laws applicable in the transaction.

For instance, the perfect tender rule is part of the UCC (Uniform Commercial Code) in the United States, and it is stricter than the CISG regarding the conformity of the goods with the contract terms. However, even the CISG acknowledges that certain breaches, like non-delivery of goods, can allow the buyer to excuse performance under the contract. The correct answer is 2) The buyer must generally give notice to the seller of any defect in the goods and then allow the seller a reasonable time to cure the defect.
