However, the political and business objectives blur the purpose of these tools, not only from the moment they are signed, but in the followed policy actions adopted to support the different sectors that could be violated. The maize agro-industrial chain represents a very important phase for the country's food security, since this is a fundamental input for thousands of products in different industries, and fundamentally in the production of food source of energy and protein for humans. This work constitutes a first step in understanding the importance of the maize agro-industrial chain and the effects of trade agreements that affect it the most, since they expose their actors to competition with the most efficient producers of this kind of grain throughout the world: United States of America, Argentina and Brazil.enAcceso completotrade agreementtariff preferenceimportstaxTesis
