Add to ORKGI discuss the impact of color-octet contributions to inclusive $J/\psi$ photoproduction at HERA. Emphasis is put on resolved photon processes and on $J/\psi$ 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
