Hetro Cordial Labeling (HCL) is a graph labeling technique in which a bijection assigns labels from {0, 1} to the vertices of a graph, and the induced edge labeling is determined by the labels of the corresponding end vertices. A graph is said to admit HCL when the numbers of vertices and edges receiving the labels 0 and 1 differ by at most one. In this paper, the Hetro Cordial Labeling property is investigated for several classes of graphs. Explicit vertex and induced edge labeling schemes are constructed for the Lotus Inside a Circle (LCₙ), Twig (T₍gₙ₎), Krackhardt Kite, Bull, and Fish graphs. For each graph, the proposed labeling satisfies the required balance conditions on the vertex and edge labels. These results establish that the considered graphs admit Hetro Cordial Labeling and contribute to the study of the labeling properties of specific graph structures.
