ICC Uniform Customs and Practice for Documentary Credits (UCP 600)

Foreword
This revision of the Uniform Customs and Practice for Documentary Credits (commonly called UCP) is the sixth revision of the rules since they were first promulgated in 1933. It is the fruit of more than three years of work by the International Chamber of Commerce’s (ICC) Commission on Banking Technique and Practice. ICC, which was established in 1919, had as its primary objective facilitating the flow of international trade at a time when nationalism and protectionism posed serious threats to the world trading system. It was in that spirit that the UCP were first introduced – to alleviate the confusion caused by individual countries’ promoting their own national rules on letter of credit practice. The objective, since attained, was to create a set of contractual rules that would establish uniformity in that practice, so that practitioners would not have to cope with a plethora of often conflicting national regulations. The universal acceptance of the UCP by practitioners in countries with widely divergent economic and judicial systems is a testament to the rules’ success.
