Recently, Cu$_2$SnS$_3$ has been theoretically proposed as a type-II NLSM, with its Fermi surface containing only one nodal ring. Here, we demonstrate how uniaxial, equi-biaxial, and equi-triaxial strains affect the nodal line state of the $Imm2$-phase of Cu$_2$SnS$_3$ by using state-of-the-art ab-initio calculations.
