The main purpose of this study is to examine the antecedents of SME importer trust and commitment to foreign supplier relationships in a Latin American emerging market economy. Insuﬃcient consideration has been given in the literature to international buyer–supplier relationships and especially small to medium-sized enterprise (SME) importers. To address this gap in our knowledge, and drawing on the internationalization process and resource-based view of the ﬁrm, this study explores the ﬁndings of a study conducted with 155 Chilean SME importers, identifying the factors that drive their relationship trust and commitment to North and South American and Western European export manufacturers. The analysis revealed that importer–supplier cultural similarity positively aﬀects knowledge and experience, and SME importers’ relationship trust. Furthermore, relative advantage positively signiﬁcantly aﬀects importer relationship commitment. Subsequently, knowledge and experience and relationship trust lead to SME importers being committed to importer–supplier relationships. Finally, metric and structural invariance tests suggest that the category of imports (industrial and consumer) does not emerge as an issue, but it does reveal that path relationships are diﬀerent and stronger in the consumer SME importer context.
