The objective of this paper is to identify the determinants of intra-industry trade (IIC) between Brazil, the European Union and China, from 2006 to 2017. For this, we used the gravitational model of trade with panel data by Least Squares. Ordinary and by Poisson Pseudo-Maximun-Likelihood (PPML). Data were collected from Comex Stat, Worl Bank and CEPII sites. Regarding the results achieved, it was found that Brazilian intra-industry trade with the European Union and China is low and showed a decrease over the analyzed period. Regarding the determinants, it was found that the cost of trade negatively affects this trade, that is, the higher the trading costs between Brazil and its trading partners, the lower the IIC tends to be between them. On the other hand, the economic size, income similarity and degree of openness of the trading partner positively affect Brazil's IIC with the analyzed partners. [ABSTRACT FROM AUTHOR]
