This study assesses the competitiveness of the fats and oils sector in Colombia in 2019 using a peer group approach. The analysis is applied to 13 companies in the sector classified as individual small- and medium-sized enterprises. The main findings were developed considering the reports of the Superintendence of Companies in 2020. The methodology used is a competitiveness analysis supported by financial indicators and the data envelopment analysis under the Charnes, Cooper & Rhones -CCR- model, considering the value of assets and revenues as input and profitability indexes (operating margin, return on assets, and return on equity) as output. The companies that are efficient and should be role models were identified. The main findings were the low attractiveness of the sector with 0.253 (it should be greater than 1 and grow over time), the business success level according to which a company located in the Department of Casanare is the leader, and the relationship between the variables that reflects an average technical efficiency of 0.7162 (on a scale of 0 to 1).
