This study analyzes the public policy in the context of rural Amazonian populations, with an example of the Minimum Price Guarantee Policy for Socio-biodiversity Products. The objective is understanding, from the perspective of açaí extractivists, the motivations and bottlenecks that lead them to not access the policy and therefore receive the subsidy to which they are entitled when selling below the minimum price. The research was conducted with extractivists from Mazagão, the second municipality of the Amapá state in terms of fruit production. Bibliographic research, documentary investigation, field diary, focus group, application of questionnaires and interviews were the methodologies used. The results of the study show that the motivations are linked to four main bottlenecks that discourage extractivists and prevent them from accessing the PGPM-BIO: 1) little dissemination of qualified information for the producer; 2) the informal, relational based model, the supply chain governance; 3) the absence of internet infrastructure; and 4) the use of bureaucratic means that are distant from the extractivists' reality. The PGPM-BIO, despite starting from the rural workers' demands and being relevant as a supplement of income, has little impact on açaí extractivists in the north of the country, and in particular in Amapá.
