The parton model is used to calculate the forward virtual Compton scattering amplitude off hadrons in the deep inelastic region. Inserting it into the Cottingham formula for the electromagnetic mass difference of hadrons, we obtain the vanishing deep-inelastic contribution to the ΔI=2 mass difference and the logarithmically divergent contribution to the ΔI=1 mass difference, the sign of which depends on the choice of specific models for the parton : the quark, quartet, two-triplet and three-triplet models. The quartet-type model proposed by Namiki and Tanaka seems to be preferable.
