Recent measurements of final states including charm hadrons observed at the HERA collider are presented. The H1 and ZEUS collaborations combined their D* differential cross section measurements and reach precisions as good as 5-10%, whereas the theory uncertainties are much larger. Using the ZEUS experiment, D* production was measured at different centre-of-mass energies. The production of D1 and D*2 mesons were also measured. Charm fragmentation fractions were obtained for various charm hadrons and are found to be compatible with data collected at e+e- colliders. Finally, the production of inelastic J/psi mesons in the hadronic final state is investigated.
