This paper investigated conditionally computable global error bounds for tensor complementarity problems (TCP) and vertical tensor complementarity problems (VTCP). Existing global error bounds for TCP and VTCP rely on an unknown exact solution vector, which cannot be numerically evaluated in practice and thus limits their applicability. To address this limitation, we established conditionally computable global error bounds under structured tensor assumptions. The derived bounds only require an arbitrary feasible test vector and are independent of the unknown true solution. Moreover, our theoretical results generalized several classic error bound theorems for linear complementarity problems (LCP), such as the Mathias–Pang and Chen–Xiang estimates. Numerical examples were presented to verify the tightness and computational efficiency of our proposed bounds.
