CHCIW were founded in 1956 as the oldest privately owned sulphuric acid plant in Taiwan. Having grown steadily with the changing times, we have witnessed Taiwan changing from from her humble beginning through the period of rapid economic growth. Facing competition from the open international market, we have closely followed market trends, adjusted product development strategies, moving from basic inorganic chemicals (applications include: water treatment, detergent, paper making, textile, PCB, etc) to specialist organic chemicals (applications include: dyes, plastics, chemical textiles, IC wafers, display panels, electronics, photoelectrics, etc) and expanding overseas markets (Mainland China, Japan, Thailand, Malaysia, USA, Mexico, Italy, etc).


With the diversification of our product applications, our company have continued to expand and invest in research personnel, production techniques and analysis equipment. We combined our own industrial experience to collaborate with clients to develop new products and processes, nurturing our ODM ability to deliver customized products to meet customer demands. We also actively collaborate with government and research institutes to work on product development projects, searching for new opportunities to develop more varied products and applications (PPT electronic grade sulphuric acid, sulfonated products: SIP, PTSA, BPS, Hydrogenation products: ODA, etc) to create impetus for company growth.
