We present a calculation of the next-to-leading order QCD corrections to the partonic cross sections contributing to single-inclusive high-p{sub T} hadron production in collisions of transversely polarized hadrons. We use a recently developed projection technique for treating the phase-space integrals in the presence of the cos(2{phi}) azimuthal-angular dependence associated with transverse polarization. Our phenomenological results show that the double-spin asymmetry A{sub TT}{sup {pi}} for neutral-pion production is expected to be very small for polarized pp scattering at RHIC and could be much larger for the proposed experiments with an asymmetric pp collider at the GSI.
