It depends on the terms of the free trade agreement and what is agreed between the parties. The concept of free trade is the opposite of trade protectionism or economic isolationism. The largest multilateral agreement is the agreement between the United States, Mexico-Canada (USMCA, formerly the North American Free Trade Agreement (NAFTA) between the United States, Canada and Mexico. Look at canada Tariff Finder, a free tool that allows Canadian exporters to find tariffs for a given commodity in a foreign market. Unlike a customs union, parties to a free trade agreement do not hold common external tariffs, i.e. different tariffs, or 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.  1. Free access to all markets in Latin America for U.S.
products and investors; Removing all tariff and non-tariff barriers. On the other hand, some local industries benefit. They are finding new markets for their duty-free products. These industries are growing and employing more labour. These compromises are the subject of endless debate among economists. 3. Protecting the intellectual property of U.S. companies in Latin America.
Latin American nations should recognize U.S. patent laws; These were mainly the pharmaceutical industry, software and trademark protection. However, biopiracy protection mechanisms were not considered. The benefits of free trade were outlined in On the Principles of Political Economy and Taxation, published in 1817 by economist David Ricardo. It is important to note that the origin of the goods is not determined by the shipment of the goods. On the contrary, there are complex rules for determining the origin of goods agreed and documented in a free trade agreement. 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. In this definition, the North American Free Trade Agreement (NAFTA) (1992) is a free trade agreement, the Southern Common Market (Mercosur) (1991) is a customs union, although an “incomplete customs union” since not all tolls are reduced to the same level and trade conflicts are recurrent. The U.S. Free Trade Area (FTAA) provided by the United States would, once it comes into force, a free trade zone from Alaska to Tierra del Fuego. These occur when one country imposes trade restrictions and no other country responds. A country can also unilaterally relax trade restrictions, but this rarely happens. This would penalize the country with a competitive disadvantage. The United States and other developed countries do so only as a kind of foreign aid to help emerging countries strengthen strategic industries that are too small to be a threat. It helps the economies of emerging countries to develop and creates new markets for U.S. exporters. Public actors expect a wider internal market for integrated projects
