This study examines how ethical moral values and trusted halal information shape halal food purchase commitment among the Indonesian Muslim diaspora in Europe. Integrating value–cognition–behavior and information trust perspectives, this study proposes a dual-pathway model comprising Ethical–Moral Halal Value Attribution (EMHVA), the Halal Information Trust Ecosystem (HITE), and the Halal Quality and Safety Heuristic (HQSH). Data were collected from 173 respondents across nine European countries and analyzed using PLS-SEM. EMHVA does not directly influence purchase commitment but significantly affects HQSH, indicating a strong indirect effect. In contrast, HITE has a significant direct effect on purchase commitment and a weaker effect on HQSH. The mediating role of HQSH in the HITE pathway is marginal. These results suggest that ethical values operate through cognitive evaluation mechanisms, whereas trusted information directly reduces uncertainty and strengthens commitment. This study contributes to the literature by introducing a dual-pathway model that distinguishes between value- and information-driven mechanisms of halal consumption. Practically, it highlights the importance of strengthening credible halal information systems and enhancing quality signaling to support diaspora consumers in complex market environments.
