The tin-substituted superconducting system DyBa2Cu3-3xSn3xOy was investigated from $x{=}0.025$ to $x{=}0.4$ by measurements of electrical resistivity and ac susceptibility, X-ray diffraction, and Mössbauer spectroscopy. It was found that the substitution of Cu by Sn does not affect the zero-resistance temperature until $x{\geq}0.25$ and results in the presence of a second phase. An anomaly in the temperature dependence of the Mössbauer recoil-free fraction near 70 K was observed for the sample with nominal composition DyBa2Sn3Oy.
