1. About Us
Quality through expertise. Cherishing the Earth's resources, creating circular value
Ying Chang Technology Industry Co., Ltd. was founded in August 2002 and is located in an industrial park in Tainan, Taiwan. Under the leadership of Chairwoman Dr. Kuan-Yi Wang, we combine scientific management with professional chemical engineering expertise, focusing on the manufacture of industrial chemicals and on turning industrial by-products into reusable resources.
"Manufacturing is not just about making products — it is about making quality consistent and keeping our customers' needs at heart."
For more than twenty years, this belief has been at the core of how Ying Chang operates. From raw materials and processing to finished products, we rigorously control every step, answering our customers' trust with consistent quality and dependable supply.
We also believe that the value of many resources should not end after a single use. Through professional chemical processes, Ying Chang treats sulfuric acid used in semiconductor manufacturing and reacts it with other raw materials to produce high-purity compounds that return to industrial use — extending the value of resources that have already been used.
To meet market demand, Ying Chang's second plant has been completed. With automated control and smart management, it further improves quality consistency, production efficiency and supply flexibility, laying an even stronger foundation for long-term partnerships.
Cherishing the Earth's resources is Ying Chang's founding commitment; creating circular value through technology is the direction we keep working towards. We put this responsibility into practice in manufacturing and operations, so that business growth and environmental sustainability go hand in hand.
2. Our Four Commitments
Professional Manufacturing | Turning resources into value through technology
Combining mature chemical technology with standardised processes to improve raw-material efficiency and turn resources into industrial chemicals of consistent quality that meet application requirements.
Quality Assurance | Earning trust with consistent quality
Inspection of raw materials, processes and finished products, together with process-data management and product traceability, lets us track quality changes and maintain product consistency and batch-to-batch stability.
Co-creation with Customers | Building long-term partnerships through understanding
We take time to understand customers' actual needs and application conditions, providing technical support and customised solutions to tackle process challenges together and create shared value.
Sustainability Responsibility | Cherishing finite resources through circularity
We turn industrial by-products into reusable resources, reducing resource consumption and environmental impact, and making the circular economy part of everyday operations.
