  We derive a strong bound on the chromo-electric dipole moment of the charm
quark, and we quantify its impact on models that allow for a sizeable flavour
violation in the up quark sector. In particular we show how the constraints
coming from the charm and up CEDMs limit the size of new physics contributions
to direct flavour violation in D meson decays. We also specialize our analysis
to the cases of split-families Supersymmetry and composite Higgs models. The
results we expose motivate an increase in experimental sensitivity to
fundamental hadronic dipoles, and a further exploration of the SM contribution
to both flavour violating D decays and nuclear electric dipole moments.
