The present study dealing with Russia and Germany undertakes to investigate the practical effect of tariffs on business and entrepreneur rather than the oft-discussed role of tariffs in international politics. Evidence from German industrial archives demonstrates that businesses were less concerned with tariff issues than one might expect from firms depending on exports. It shows that impediments other than customs duties (expenditures for credit, service, freight, investment, marketing; and competition, restrictions imposed on government orders, subventions, production costs abroad, technological changes) by far overshadowed inhibiting effects of tariffs. Circumspect responses of the entrepreneur helped to minimize the economic role tariffs played.
