Due to the globalisation, it has become necessary for organizations to be involved in international business, and the globalisation of the marketplace in general has increased the export. When expanding to international markets, companies might face some obstacles and barriers, which makes it an important topic in the research field of international marketing and strategy. Since most research focuses just on the importance of the expansion barriers, it would be of importance to provide empirical evidence on what types of explanatory factors that are associated with firms’ perception of expansion barriers. Purpose: Gain an understanding of different explanatory factors regarding expansion barriers for companies’ expansion on international markets. Methodology: The research approach was quantitative with mainly primary data, which was collected through a questionnaire distributed through e-mail. The sample frame was Swedish companies that exporting goods to Norway, Poland, Russia and/or the Baltic region. A total of 157 completed questionnaires, response rate of 20%, were collected and was the foundation for the analysis and results. Conclusion: The explanatory factors that are associated with the perception of expansion barriers were; Geographical and Cultural distances, Market experience and Institutional collaborations. The fourth explanatory factor, intermediating strategy, has in this study no association to the perception of the barriers.
