Introduction

A half century ago in the United States , it became clear that modern commercial practices required a modern commercial law. Thus, in the early 1950s The American Law Institute, in a joint project with the National Conference of Commissioners on Uniform State Laws, drafted the first version of the Uniform Commercial Code ("UCC") and published it in 1952. Considered to be one of the most important legislative measures in the history of US commerce, the UCC has been adopted by every state except Louisiana . It is a unified, comprehensive set of laws that encompasses all domestic businesses transactions.

After decades of effort, the United Nations Commission on International Trade Law ("UNCITRAL") promoted the adoption of the CISG, which became the law in the US in 1988.
Today the CISG applies to 76 other nations as well, including most of the major trading nations. What follows is an analysis of both codes, an identification of the major differences that exist between them and to finish, we’ll present two different cases and advice which code shoul be usen in court for each of them.

Applicability of the CISG

Unless the parties specifically indicate that it does not apply, the CISG will be the governing law pertaining to all commercial contracts for the sale of goods between parties having their places of business in different countries which have adopted the CISG.
