How does the United Nations Convention on Contracts for the International Sale of Goods reduce choice-of-law problems?

The United Nations Convention on Contracts for the International Sale of Goods (CISG) reduces choice-of-law problems by providing a unified set of substantive rules for international sales, rather than merely establishing rules to resolve conflicts between divergent national laws.1

While some international efforts focus on harmonizing "conflicts rules"—which dictate which country's law applies to a contract—the CISG takes a more comprehensive approach by unifying the actual sales laws themselves. By establishing a common legal framework that participating countries adopt into their own national legislation, the CISG minimizes the need for courts to navigate the complexities of conflict of laws. This approach effectively bypasses the uncertainty that arises when parties must determine which national law governs a transaction, as the convention provides a consistent, predictable set of obligations for both buyers and sellers in international trade.1
