Raw Material Survey

“100% Green Products in accordance with International Regulations, Industry Standards, and Customer Requirements” is Unimicron's commitment to green products. In order to comply with the requirements of the RoHS and REACH, Unimicron carried source and finished product management according to the specifications of the management systems and requested suppliers to survey hazardous substances to ensure that the raw materials were complied with the hazardous substances by RoHS and REACH. In 2022, there were 1,358 RoHS reports from Taiwan facilities for managing and reviewing suppliers, including 574 for direct materials, 638 for indirect materials, and 146 for packaging materials, which were 100% completed.

Hazardous Substance Control

In order to promote green product management and product safety, Unimicron's products are currently banned to use environmentally hazardous substances, and in accordance with EU regulations (e.g. RoHS, REACH, IEC 62474, etc.), a total of 1,140 substances are listed in 11 regulatory directives and customer-specific requirements, including GADSL (274 substances) and Prop65 (970 substances), which are mainly published on the official website of the regulations.

Unimicron’s products are one of the components of complex electronic products, and the most important concern for customers is the EU REACH SVHC and RoHS hazardous substances restriction directive. Unimicron’s products give priority to green materials that comply with regulations and customer requirements. Except for customer-specified materials, there are two main hazardous substances in products, including brominated flame retardants and bisphenol A. The content ratio of 4.37% based on the total sales amount of the products, corresponds to the material declaration limit value of IEC 62474 for electrical and electronic products..

Hazardous Substance Survey

Unimicron is disclosing hazardous substances to its customers by means of supplier hazardous substance surveys. After informing suppliers of the new hazardous substance control items, Unimicron requires suppliers to provide a letter of assurance of non-use of banned and restricted substances and a declaration of REACH compliance to ensure compliance with the law and Unimicron's regulations, and to keep track of the use of all materials containing banned and restricted substances and SVHCs. According to the customer's material number that uses SVHC, we reply to the customer survey form and implement source management. In 2022, we cooperated with customers in the investigation of hazardous substances of PCB and Carrier SBU in Taiwan, we conducted a total of 387 supplier surveys, with a response rate of 100%, and completed a total of 818 surveys of hazardous substances required by customers, with a completion rate of 100%.

Reduction Plan of Hazardous Substances in Products

Improvement Plan
In order to enhance product safety, Unimicron is committed to reducing the environmental and human health hazards of the substances in our products. For example, Bisphenol A (BPA) is a chemical substance regulated by international standards and Taiwanese government regulations. To reduce the impact of hazardous substances on the environment, the products of PCB II SBU are 100% compliant with REACH SVHC for BPA concentration. The products of Carrier SBU contain Bisphenol A (BPA) under REACH SVHC according to the customer's specified substrate. If the concentration of BPA in the finished product is higher than the standard, we must notify the customer in accordance with REACH requirements.
