The inclusive production of pseudoscalar heavy quarkonia ($\eta_c,\, \eta_b,\, B_c$), double heavy baryons $\Xi_{ QQ^\prime}$ ($Q^{ (\prime)}=c,\,b$ quarks) and tetraquarks $T_{ QQ}$ in heavy ion ultraperipheral collisions (UPCs) is studied. Numerical results indicate that the experimental investigation of $\eta_c,\, \Xi_{ cc}$, and $T_{ cc}$ is feasible at the upcoming HL-LHC and future FCC. Heavy ion UPCs open another avenue for studying the production of these doubly heavy hadrons.
