promote trade between neighbours. There are five main phases of economic integration: the free trade area, the customs union, the common market, economic union and political union. Free trade zones are the most fundamental form of economic cooperation. In this regard, Member States remove all barriers to trade, while remaining free to set their own trade policy with third countries. The North American Free Trade Agreement (NAFTA) is an example. Customs union unions look like free trade zones because they were not so popular in the mass world. Key issues include unfair competition from countries where lower labour costs are reducing prices and the loss of well-paying jobs for producers abroad. In the modern world, free trade policy is often implemented by a formal and reciprocal agreement between the nations concerned. However, a free trade policy may simply be the absence of trade restrictions.
In principle, free trade at the international level is no different from trade between neighbours, cities or states. However, it allows companies in each country to focus on the production and sale of goods that make the best use of their resources, while others import goods that are scarce or unavailable domesticly. This mix of local production and foreign trade allows economies to grow faster and, at the same time, better meet the needs of their consumers. the history of the North American Free Trade Agreement (NAFTA), NAFTA has had an impact on Canada, the United States of America (particularly the U.S. labour and labour market) and Mexico. It will also discuss the current state of NAFTA, the pros and cons of the U.S. economy and the future of this historic trade agreement. NAFTA has produced many parts of the world, not just the three countries that originally signed the agreement.
At the international level, it has had several negative effects, there are two databases of access to free movement that have been developed by international organizations for policy makers and businesses: unlike a customs union, the parties to a free trade agreement do not maintain common external tariffs, which means that they apply different tariffs. , as well as other policies concerning non-members. This function allows non-parties to free themselves as part of a free trade agreement by entering the market with the lowest external tariffs. Such a risk requires the introduction of rules for determining which products originate may be preferred under a free trade agreement, which is not necessary for the establishment of a customs union.  In principle, there is a minimum processing time leading to a "substantial processing" of the products, so they can be considered original products. By the definition of products originating in the PTA, the preferential rules of origin distinguish between domestic and non-origin products: only the former are eligible for preferential tariffs provided by the ESTV, which must pay the import duties of the MFN.  The trade agreement database provided by the ITC market access map. Given that hundreds of free trade agreements are currently in force and are being negotiated (approximately 800 according to the rules of the intermediary of origin, including non-reciprocal trade agreements), it is important for businesses and policy makers to keep their status in mind. There are a number of free trade agreement custodians available at national, regional or international level.
Among the most important are the database on Latin American free trade agreements, established by the Latin American Integration Association (ALADI) , the database managed by the Asian Regional Integration Center (ARIC) with information agreements concluded by Asian countries and the portal on free trade negotiations and agreements of the European Union.  As soon as the agreements go beyond the regional level, they need help.
