The company primarily implements the following measures to guarantee product quality and after-sales service

Leveraging the Group’s nearly 30 years of experience in graphite mining, beneficiation, and deep processing, Qingdao Baohua New Materials Technology Co., Ltd. has established a comprehensive quality assurance and service mechanism covering the entire production process, ensuring customer value through consistent quality and efficient service. The company primarily implements the following measures to guarantee product quality and after-sales service:

I. Quality System Assurance

- Authoritative System Certifications: The company has obtained ISO 9001 Quality Management, ISO 14001 Environmental, and ISO 45001 Occupational Health and Safety Management System certifications, as well as IATF 16949 certification, laying a solid foundation for product quality.

- Robust Organizational Structure: A dedicated quality inspection department has been established, equipped with a standardized laboratory and advanced testing equipment to ensure comprehensive quality control from raw materials to finished products.

- End-to-End Quality Control: We rigorously screen high-quality ore sources during raw material procurement; utilize automated production lines with real-time monitoring at critical stages to ensure process stability; and conduct sampling and testing on every batch of finished products, covering indicators such as ash content, moisture content, volatile matter, iron content, pH value, bulk density, and particle size. A secondary re-inspection is performed before shipment to prevent non-conforming products from leaving the factory.

II. Product Testing Mechanism

- Dual-Check Testing: Testing is conducted once upon completion of production and again before shipment to ensure the delivered product matches the test results.

- Comprehensive Indicator Coverage: Tailored to the characteristics of different graphite products, testing items cover key indicators such as fixed carbon content, particle size distribution, and impurity content to meet diverse customer needs.

- Data Traceability Management: A comprehensive system for recording and tracing testing data has been established to ensure product quality issues are traceable and accountable.

III. Customer Service System

- Customized Services: We provide personalized product solutions based on customer needs, such as graphite products with specific particle sizes or fixed carbon content, as well as customized packaging and logistics solutions.

- Efficient Response Mechanism: A dedicated customer service team is established to quickly respond to inquiries, orders, and after-sales requests, providing technical support and application guidance.

- After-Sales Guarantee: In the event of verified product quality issues, promptly process returns or exchanges and assume corresponding responsibility; conduct regular customer follow-ups to collect feedback for continuous optimization of products and services.

IV. Continuous Improvement Mechanism

- Technology Innovation-Driven: Increase R&D investment, focus on the needs of the new energy and high-end manufacturing sectors, drive the iterative upgrading of products such as spherical graphite and high-purity graphite, and enhance product performance and quality.

- Closed-Loop Quality Management: Establish processes for handling customer feedback and internal quality issues; analyze root causes, formulate corrective measures, and track their implementation to form a PDCA cycle, thereby continuously improving quality management standards.

- Employee Quality Training: Conduct regular training on quality awareness and skills to reinforce quality responsibility among all staff and integrate quality principles into every aspect of production and operations.
