We discuss the production of transversely polarized hyperons in semi-inclusive deep inelastic scattering in the framework of the collinear twist-3 factorization. In this framework, the twist-3 cross section consists of three contributions depending on the origins for the polarizations: (i) Twist-3 distribution in the initial proton combined with the twist-2 transversity fragmentation function (FF) for the final hyperon, (ii) Twist-3 quark FF for the hyperon and (iii) Twist-3 gluon FF for the hyperon. In this talk. we focus on the first two contributions, since they are expected to become dominant contribution. We present the twist-3 cross section in the leading order (LO) with respect to the QCD coupling constant for all the five structure functions which have different dependences on the azimuthal angles. We also discuss the matching with the TMD framework in the small-$P_T$ region. The present result is important for the future EIC experiment.
