This paper presents the effects between Logistics Network and Value-Added activities 3PL environments and its effect on the Financial and Strategic Performance of Mexican Maquiladoras companies. The significant increase in outsourcing transportation services in freight transport at the border Mexico-United States has inspired this research. The paper presents four hypotheses, tested with data from 158 responses to a questionnaire applied to engineers from the manufacturing industry in Ciudad Juarez (Mexico). The hypotheses were tested statistically using the partial least squares technique. Results indicate that a good design of a Logistics Network has a positive effect on Strategic Performance through transport logistics planning to reduce distribution times and costs. Additionally, the Value-Added services offered by a 3PL positively affect Strategic Performance through labeling-marking, packaging, and reassembling of products. Also, the Strategic Performance has a positive effect on Financial Performance through flexibility and risk minimization of 3PL provider, and this is the enormous effect that arguing theoretically and demonstrating empirically that the outsourcing of 3PL incremented the economic benefits to the quantity of 76.20% between Financial Performance and provides a reference to make decisions according to strategies to incorporate 3PL in such maquiladora industries.
