We find the fusion rules for the quantum analogues of the complex reflection groups Hsn = ℤsSn. The irreducible representations can be indexed by the elements of the free monoid ℕs, and their tensor products are given by formulae which remind the Clebsch–Gordan rules (which appear at s = 1).

Keywords: Reflection group, quantum group, fusion rules
