  We introduce a spin polarization-scaling map for spin-$j$ particles, whose
physical meaning is the decrease of spin polarization along three mutually
orthogonal axes. We find conditions on three scaling parameters under which the
map is positive, completely positive, entanglement breaking, 2-tensor-stable
positive, and 2-locally entanglement annihilating. The results are specified
for maps on spin-$1$ particles. The difference from the case of
spin-$\frac{1}{2}$ particles is emphasized.
