  We investigate the high $Q^2$ (photon virtuality) limit of single-inclusive
hadron production in DIS (SIDIS) at small $x$, using the color glass condensate
formalism at next-to-leading order. We focus on the $\Lambda_{QCD}^2 \ll
\mathbf{p}_h^2 \ll Q^2$ kinematic regime where $\mathbf{p}_h$ is the produced
hadron transverse momentum, and extract the Sudakov double logarithms. We
further argue that compatibility between the CGC calculation and TMD
factorization at one-loop order can only be achieved if the small-x evolution
is kinematically constrained.
