Raw Material Control


Raw materials are the foundation of our products; therefore, ensuring a stable supply and consistent quality is paramount to effective quality control.

Henan Yeda New Materials Technology Co., Ltd.

Stable supply


For raw materials such as bauxite, brown fused alumina, and white fused alumina, the company sources from at least three suppliers to ensure a reliable supply of products.

The company has established comprehensive supplier profiles and set up a dedicated procurement department to conduct due diligence and verify suppliers, thereby ensuring supplier stability.

Raw Material Inspection


For each batch of incoming raw materials, procurement personnel collect samples prior to receipt and submit them to the quality inspection department for compositional analysis and record‑keeping. Only after the samples meet the required specifications are bulk purchases authorized; the bulk shipments then undergo a second round of testing, and they may be stored and used only upon confirmation that they conform to the reference standards.

Secondary inspection of raw materials ensures that quality is sound at the source.
