It all started from June 15th, 1972. Under the direction of Mr. Suchin Ratanachaithong, Economic Chemical Company Ltd. began production of ‘Bat’ brand fertilizers and agricultural chemicals for the local market. Mr. Suchin realized that with the growth in the agricultural sector in Thailand, demand for high quality and technology driven chemicals will also grow. He also saw the growth of imported chemicals and understands the dangers associated with free movements of dangerous chemicals which can be good for short term gains but will be hazardous for Thailand as a country in the years to come. His love for the safety and wellbeing of Thailand summarizes what we believe in and what we have achieved to this day. This belief is enhanced by the addition of Montedison. An Italian high quality chemical manufacturer. The collaboration in production brought Thep Siam Co., Ltd. into existence. Their safe and high quality chemical manufacturing technology propelled us towards higher sales volume and presence in the market. In 2003, Mr. Phanit Ratanachaithong took over the leadership with the same values and principles. The constant rejuvenation of talent and creativity is continued by Dr. Widodo and Miss Meivy Ratanachaithong.
