In this paper we investigate the impact of the higher-twist effects, resummed by the non-linear approaches for the QCD dynamics, on the inclusive observables that will be measured in future electron-ion colliders. We assume a phenomenological model for the dipole-nucleus scattering amplitude which takes into account the non-linear corrections and estimate the contribution of the different twists for 
, 
and 
considering different values of the Bjorken-x variable, photon virtuality 
and atomic number A. A comparison with the full predictions is performed and the impact of the distinct twists is estimated. Our results indicate that a future analysis of the logarithmic slope and longitudinal structure function will allow us to probe the presence of the non-linear effects on the QCD dynamics.
