This publication describes the results obtained, from the development of the main research objective of generating a fair trade measurement instrument in each of the stages of the supply chain of Sacha inchi fruit in the Amazon region of Colombia. The study allows us to answer the question: ¿How fair or unfair is trade in each of the stages of the Sacha Inchi fruit supply chain in the Amazon region of Colombia? For its fulfillment, it was necessary to first determine the main variables, the assessment scale, the degrees of compliance, the relationship between the assessment and the ideal achievement, the comprehensive scope; and finally, the methodology for monitoring, assessment of opportunities for improvement, resulting from the evaluation of the comprehensive scope of economic justice in each of the stages of the supply chain. A mixed methodology is used, a type of probabilistic sampling; where the sample is 913 companies (Production 500 and marketing 413). This will test a series of investigative hypotheses that allow identifying the existence of fair and/or unfair trade in each of the stages of the Sacha Inchi fruit supply chain in the Amazon region of Colombia. The foregoing raises an academic and research precedent about the Sacha inchi fruit, with a valuable theoretical-practical foundation for the management of the supply chain in the Amazon region of Colombia.
