We investigate the high Q2 (photon virtuality) limit of single-inclusive hadron production in deep inelastic scattering at small x, using the color glass condensate formalism at next-to-leading order. We focus on the ΛQCD2≪ph2≪Q2 kinematic regime, where ph is the produced hadron transverse momentum, and extract the Sudakov double logarithms. We further argue that compatibility between the color glass condensate calculation and transverse momentum dependent distribution factorization at one-loop order can only be achieved if the small-x evolution is kinematically constrained.
