Furthermore, the company seeks marketing and production strategies connected to local and foreign market while maximizing efficiency. Moreover, the company moved away from the existing model in a local oil industry that was recognized as an industry for domestic demand. Instead, the company exported more than 60% of produced items every year by concentrating on entering the overseas market. Now, the company has a leading role in changing to a high value exportation company from the local oil industry. While maintaining competition obtained from investment, the company promoted an expansion project of the Onsan Factory including 2nd Aromatic Complex to increase profit, and started commercial operation from April 2011. After 3 years of planning, design, and construction, the project was successfully completed, and the company started to possess the groundwork to take a leap as an excellent company with the best competition in the petro-chemistry area in the provision of products from Korea and Overseas.
