The purpose of this study is to investigate the changes in the recovery of equipment using full containers loaded with freight instead of direct container transportation according to the sales policy considering the cost of transporting the containers. The EMU operation case was analyzed. The policies implemented by Company A to provide EMU credits depended only on the relative accountability contribution margin per box (RA CMPB) for the profitability of backhaul full freight. Therefore, these policies resulted in limitations in sales based on profitable accountability (PA) CMPB, which is more profitable. Moreover, while some Asian regions have surplus equipment, many Asian destinations to which their freight is exported have equipment shortages. Thus, in some cases, service sales to the regions with surplus equipment generated greater company-wide profits when compared with the return of empty containers or sales to the regions with insufficient equipment. In other words, the conditions for providing EMU credits should be changed, and even the full freight between regions with surplus equipment should be provided with credit amounts in which potential factory and transport costs in a destination are pre-reflected.
