We study the role of purely external kinematical approximations in inclusive deep-inelastic scattering within QCD factorization, and discuss how an observed improvement obtained by accounting for target mass kinematics could be interpreted in terms of general properties of target structure. We argue that such an improvement implies a hierarchy of nonperturbative scales within the hadron.
