The goal of this paper is to analyse Lithuanian metalworking sector in order to define whether any of international trade theories explain its international trade’s pattern. In order to reach the goal scientific literature analysis was made to gain knowledge about different international trade theories. The analysis of other author’s works in this field was made as well as statistical data of Lithuania’s metalworking sector analyzed.
