The objective of this work was to identify the management process of the rice mill supply chain in the Depressão Central area of Rio Grande do Sul state also advancing in the understanding of the aspects that involve the transaction between the agricultural and industrial sectors. The data was collected through the sending of one questionnaire to each one of the rice mill owners and interviews later on. The region comprises 22 rice mills, 10 of which did return the questionnaire. The results allowed for two important conclusions: a) it could be observed that the rice mills are predominantly supplied by farmers of the region who have good storage structures, which allows them to better plan the commercialization of the products and to reduce the seasonal effect of the prices on the farm income; b) it was observed that the supply chain features few coordination mechanisms, and that the governance still happens predominantly by via market. There is a predominance of non-contractual relations between industry and farmers; there is practically no occurrence of mechanisms of control as well as of information exchange between industry and farmer; and the use of mechanisms of orientation and technical assistance is reduced, predominating only in the cooperative organizations and in one of the private companies.
