We show that any solution of the scalar conservation law (u + k*u)(t) + sigma(u)(x) = 0 starting from spatially periodic initial datum stabilizes to its integral mean as time goes to infinity. No convexity or 'genuinely non-linear' like conditions are assumed concerning sigma. (C) 1997 by B. C. Teubner stuttgart-John Wiley & Sons Ltd.
