In this paper, we focus on the formulation of two multi-variate composite (generalized) ratio-type estimators for the population mean in the presence of $(p + 1)$ supplementary variables. Estimation mechanism has been carried out in the framework of a two-phase sampling procedure when no information is sought on the population mean of the main supplementary variable but the population means of the rest $p$ supplementary variables (called as the additional supplementary variables) are known accurately.
