Considering the quantum kinetic-theory description for interacting massive spin-half fermions, we derive, using the Wigner function formalism, the general collision kernel containing both local and non-local particle collisions. We assume that the spin effects can have both classical and quantum origins. To track the effects of such different contributions we use the semi-classical expansion method to obtain the generalized kinetic equations with spin. We then employ the ansatz for the equilibrium distribution function and derive global equilibrium conditions, assuming the total angular momentum is conserved in the microscopic collisions.
