The high-precision HERA data are used to search for Beyond
the Standard Model contributions to electron-quark scattering
in the framework of eeqq contact interactions (CI). Combined measurements
of the inclusive deep inelastic cross sections in neutral and charged
current $ep$ scattering are considered, corresponding to a luminosity
of around 1 fb$^{-1}$. The analysis of the inclusive $ep$ data is based
on the simultaneous fits of parton distribution functions
together with contributions of CI couplings to $ep$ scattering.
Results are presented for different CI scenarios and the resulting
95% CL limits on the CI mass scales extend up to the 10 TeV scale.
