The condensates are calculated including \$m\_um\_d\$ contributions as well as electromagnetic corrections. Appealing to the ferromagnetic-like nature of the condensates under electromagnetic symmetry breaking, we derive some constraints for the electromagnetic low-energy constants (LEC). We also establish matching conditions between the SU(2) and SU(3) LEC involved, including all the relevant isospin-breaking contributions of the same order. In addition, we find that the sum rule relating quark condensate ratios in SU(3) receives electromagnetic corrections of the same order as the \$m\_um\_d\$ ones previously derived.
