Through regular reviews and ongoing improvements, we strive to achieve better corporate activities.

Human Rights and Labor Practices

UNIFIVE respects fundamental human rights in all countries and regions where it conducts business and promotes labor practices in line with internationally recognized human rights standards.

Responsibility in the Supply Chain

UNIFIVE recognizes the fulfillment of social responsibility throughout the entire supply chain, not only within its own business activities, as an important issue. At each stage of procurement, manufacturing, and supply, we are working on compliance with environmental regulations, management of hazardous substances, and responsible sourcing of raw materials.

Management of Contained Chemical Substances

Products components and materials are managed for contained chemical substances in accordance with the RoHS Directive and the REACH Regulation. During incoming inspection, all purchased components are tested using X-ray fluorescence analyzers to measure the content of RoHS-specified hazardous substances and confirm compliance with regulatory limits. In addition, as a countermeasure against ion migration in DC plug parts, we have continued to manage the non-inclusion of red phosphorus flame retardants since 2016. Standards for environmentally hazardous substances are regularly updated based on the laws and regulations of each country and customer requirements.

Responsible Mineral Sourcing

UNIFIVE strives for responsible mineral sourcing to ensure that minerals (tin, tantalum, tungsten, gold, etc.) from conflict-affected and high-risk areas do not become funding sources for armed groups or antisocial forces. Based on the intent of the OECD Due Diligence Guidance for Responsible Supply Chains of Minerals from Conflict-Affected and High-Risk Areas, we are working to eliminate the use of conflict minerals in our Products and also respond to customer requests for conflict minerals surveys.

Green Procurement

We strive to prioritize the adoption of components and materials with low environmental impact and confirm environmental management initiatives with our suppliers. Including compliance with our customers' green procurement standards, we promote environmental consideration throughout the entire supply chain.

Supplier CSR Audits

We require all suppliers to comply with standards related to social responsibility. We conduct annual social responsibility surveys to evaluate suppliers' CSR initiatives and, when necessary, follow up on corrective actions and manage the related records.

Information Management

Confidential information entrusted to us by customers and business partners is protected under a strict management system to prevent leakage to third parties. Personal information of employees and related parties is also properly managed in accordance with the personal information protection laws and regulations of each country and region.

In addition, we implement measures to defend against cybersecurity threats, and we appropriately disclose information regarding our business activities, the safety of our Products, quality, and environmental initiatives through our website and other channels.

Quality Management

UNIFIVE positions quality as the most important foundation of its business activities and has established a company-wide quality management system based on the concept of Total Quality Control (TQC) in accordance with JIS Z 8101 (Quality Control Terminology).

Quality Control System

Each department, including design, manufacturing, quality assurance, and management, works in coordination to control quality throughout all processes, from the collection of specification information to design, development, mass production, and post-shipment maintenance activities. At the design stage, the QA department conducts design verification from a third-party perspective, and at the manufacturing stage, a management system based on process FMEA is implemented. From daily quality improvements to handling market complaints, we consistently carry out root cause identification, corrective actions, and recurrence prevention.

Certification Acquisition and Standards Compliance

In addition to obtaining ISO9001:2015 and ISO14001:2015 certifications, we comply with various international safety standards and factory certifications, including Japan PSE, UL/CUL, TUV, EK-MARK, CCC, and BSMI. We not only meet the safety standards of each country but also comply with customer-specific safety requirements, ensuring traceability of materials, components, and processes.

Continuous Quality Improvement

At the beginning of each year, quality objectives are established across all departments, and management reviews are conducted monthly to allow executives to monitor progress. In the event of a quality issue, we promptly verify the facts, report quickly and accurately to both internal and external stakeholders, thoroughly investigate the root cause, and implement measures to prevent recurrence.
