Green Product Management

Unimicron is committed to the implementation of green product management with the three principles of “compliance with green specifications and requirements”, “green procurement”, and “green supply chain”, and sets the quality target of HSF. The use of environmentally hazardous substances on products is strictly prohibited, which extends to Quality Management, Procurement, Products, R&D, Manufacturing, Sales, and other departments to consider green materials amid the process design. The purchased raw materials meet the requirements of international laws and regulations such as the Restriction of Hazardous Substances Directive (RoHS), Registration, Evaluation, Authorization, and Restriction of Chemical (REACH), Directive of Packaging and Packaging Waste, China RoHS, California Proposition 65, Montreal Convention, etc. In terms of products, the requirements of RoHS and REACH are met 100%. The principles of green products and continuous improvement are implemented, to satisfy customers and comply with the requirements on green materials by international environmental protection specifications. Likewise, we fulfill our social responsibility of environmental protection.

HSF Quality Policy

To implement the four major principles of HSF quality policy, Unimicron has established various indicators to regularly track performance and achievement rates, to ensure that the policies are implemented and meet customer needs. From 2013 to 2021, the achievement rate of all HSF quality indicators was 100%, and there were no returns from customers due to HSF non-compliance.

Management System

All raw materials, packaging materials and chemicals required in the manufacturing process of Unimicron products are incorporated into the management system to achieve comprehensive management. To fulfill our responsibility and contribution as a global citizen, we are committed to not using environmental management substances that are restricted, complying with current laws and regulations, meeting the needs of our customers, protecting the environment and reducing the impact on the ecosystem. We established measures for source, process, and finished product management to comply with international standards and customer requirements for controlled substances, and to curb the environmental and social hazards caused by the life cycle of our products.

Raw Material Management

To implement the source management of green products, Unimicron has developed a complete internal control process and operation regulations for hazardous substances, established an audit mechanism starting from the introduction of raw material evaluation, and adopted the E-Pr system for management, required suppliers to provide third-party inspection reports and update annually. We also publish the green procurement requirements, conflict minerals investigation form, and ask suppliers to confirm and reply with a non-use (banned and restricted substances) guarantee letter, conflict-free minerals and RBA Commitment. Materials are required to comply with EU regulations such as RoHS, REACH, halogen-free, conflict-free minerals, etc. and listed in the Qualified Materials List after passing Unimicron's internal audit. If there are specific requirements by the customer, we must comply with the customer's control standards and supplier management regulations to fulfill our commitment to "100% compliance with international regulations, industry standards and customer requirements for green products".

Evaluating New Materials Material Determination UMT Prohibited Substances Assessment Banned Procurement and use after permission Risk Management

Control Measure

  • Hazardous Substance List and Reduction Plan: Based on RoHS, REACH Substances of Very High Concern (SVHC), customer regulations and other international regulations, we develop a Hazardous Substance Control List and related reduction plan to grasp the use of substances in the list.
  • REACH Compliance Declaration: Investigate the compliance of suppliers with REACH regulations and implement source management of raw materials.
  • Restriction of Hazardous Substances Operational Procedures: To regulate the standard operating procedures of each authority in handling hazardous substances.

2021 Hazardous Substance Free Survey Results

In order to promote green product management and product safety, we have implemented banning measures for environmentally hazardous substances in our products and comply with the EU regulations (e.g. RoHS, REACH, etc.). There are 11 types of regulatory directives Note1 and customer requirements, totaling about 1,140 substances, of which GADSL (about 270 substances) and Prop65 (about 1,023 substances) have numerous substances, complete regulation is mainly published on their official website. After notification to suppliers and the renew hazardous substance items, we request the suppliers to reply the non-use (banned and restricted substances) guarantee letter and REACH compliance statement to ensure compliance with the law and Unimicron's regulations, so that we could manage all materials that containing substances (SVHC) Note2. Also, we reply to the customer survey to implement source management according to the customers who use SVHC.

Reduction Plan of Hazardous Substances in Products

In order to strengthen the management of hazardous substances in raw materials and products, we use X-Ray Fluorescence Analysis (XRF) to test materials and final products for hazardous substances to ensure that the delivered products meet the requirements of hazardous substance management. In addition, we continue to reduce hazardous substances in our products with the following:

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 Taiwan government regulations. To reduce the impact of this hazardous substance on environmental hormones, the products of PCB II SBU are 100% compliant with REACH SVHC international standards for BPA concentration. The Carrier Division's products 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 international standard, we must notify the customer in accordance with REACH requirements.

Substitution Plan

The Carrier SBU and PCB II SBU have implemented substitution programs and have now phased out the use of Cobalt (II) chloride (wetness indicator card and desiccant in packages), Arsenic trioxide and Arsenic pentoxide.

Finished Goods Inspections

To ensure that the products produced by Unimicron comply with the green product standards, we sample products to the third party for hazardous substance testing every year to ensure that the products meet the hazardous substance management requirements. In 2021, the Carrier SBU focused on the 10 substances of RoHS, including halogen (F, Cl, Br, I), antimony (Sb), beryllium (Be), perfluorooctane sulfonate (PFOS), perfluorooctanoic acid (PFOA), DINP, DNOP, Hexabromocyclododecane (HBCDD). The PCB II SBU focused on 10 substances of RoHS and halogens (Cl, Br). Please refer to the following files.
