Monetary values of exports were collected in the UNCONTRADE database and deflated (base year 2005). For determine the concentration, it used the methods of Herfindahl-Hirschman and the concentration ratio (CR2, CR4 and CR8) classified in the Bain criteria. The real value of Brazilian exports doors for the reporting period decreased from US$ 227.3 million in 2005 to US$ 154.3 million in 2015. The analysis of the concentration of Brazilian exports doors, by Hirschman Index-Herfindahl the period 2005-2009, showed a fall of market concentration ranging from 0.4626 to 0.2829 in the meantime. According to the criterion of Bain, the concentration was deemed too high.
