U(1)X SSM is a non-universal Abelian extension of the Minimal Supersymmetric Standard Model and its local gauge group is extended to SU(3)C×SU(2)L×U(1)Y×U(1)X. Based on the latest data of neutral meson mixing and experimental limitations, we investigate the process of mixing in U(1)X SSM. Using the effective Hamiltonian method, the Wilson coefficients and mass difference ΔmB are derived. The abundant numerical results verify that ,\,{\lambda }_{C},\,\mu ,\,{M}_,\,\tan \beta ,\,{g}_{{YX}},\,{M}_$" align="top"> and λH are sensitive parameters to the process of
