In this paper we investigate conditions for T_f1 T_f2 T_f3 - T_f1f2f3 = 0 where T_f1 , T_f2 , and T_f3 are bi-level Toeplitz operators on the Hardy space of bidisk and f_1; f_2; f_3 are bounded and measurable complex valued functions on bidisk. We also provide that T_f1 T_f2 T_f3 identical to zero matrix if and only if at least one of f_i is identically zero for 1 ≤i ≤3.
