SJL is the story of two Spanish families, San José and Lopez, who started the road transport business in Spain in 1948 and 1949 respectively. Very quickly, the two companies see their activities take off and grow rapidly outside the Spanish territory to cover other neighboring countries such as France, Germany and the Netherlands. The success is such that in 1975 the companies decide to create representative offices throughout Europe. The story does not end there, because in 1986 San José decides to push the borders a little further: Africa and in particular its entry point, Morocco. In that same year, the activity was officially launched there via the company Tremsa, which would later become SJL Maghreb, and this was a strategic turning point that would reposition the future group as a leader and essential partner in commercial exchanges by road between Europe and Africa.

The two companies merged in 2002 and a growth plan was deployed, resulting in the creation and launch of logistics activities in Tangiers, Morocco. In 2005, SJL moved to the TFZ and for the first time offered customized transit solutions to its customers. SJL then continues its growth in the Maghreb, in Tunisia where it launches its activity in 2014.
