Abstract: In recent years, the pace of industrialization has accelerated, and the pace of international trade has accelerated with it, which has increased the importance of rules of origin in international trade between global economic partners. The international organizations, with their different components, have tried to give a unified definition of these mechanisms. In general, the rules of origin are the passport of industrial products. Rules of origin play a major role in international trade, as they contribute significantly to improving the origin of industrial products between various international trading partners. The results we reached highlight that the most important indicators used are divided into two parts, first, the facilitation index, which determines how easy the rules of origin are for economic actors; secondly, the restrictiveness index, which highlights the complexity of the rules of origin for companies, on the other hand, the goal of these indicators as In general, it is to know the impact of the disposition of rules of origin on international trade, and that is based on empirical studies. By analyzing the legal texts of the different FTA between countries, we discovered that other indicators could be proposed to measure the rules of origin in international trade.
