I discuss the impact of color-octet contributions to inclusive J/ψ photoproduction at HERA. Emphasis is put on resolved photon processes and on J/ψ polarization, which will be experimentally accessible at HERA in the near future. Both analyses provide a powerful test of the NRQCD factorization approach to charmonium production.
