Semi-inclusive hadron production processes in deep-inelastic lepton-nucleon scattering (SIDIS) are important probes of the quark flavour structure of the nucleon and of the fragmentation dynamics of quarks into hadrons. In this talk, I will present the recent calculation of the full next-to-next-to-leading order (NNLO) QCD corrections to the SIDIS coefficient functions. I will also comment on the numerical impact of these corrections in different kinematical regions and on the usage of these predictions in the context of global fits.
