The base in two tinctures is supposed to refer to the village's historical division between lordships, countries and even between "Bundesländer" after the Second World War until 2004. One side belonged to the Duchy of Palatinate-Zweibrücken while the other belonged to either Lotharingia or the House of Leyen, and later Herchweiler was split along the same boundary into Bavarian and Prussian sectors. The line between the two tinctures stands for the Judenbach, the brook that was named after the Jewish inhabitants who once populated the smaller, western sector of the village, and which marked the boundary between the village's two politically separate parts. The cross goes back to an old village seal. The arms have been borne since 1983 when they were approved by the now defunct Rheinhessen-Pfalz "Regierungsbezirk" administration in Neustadt an der Weinstraße.
