On June 26–27, Chongqing Xingfa Jinguan Chemical Co., Ltd.—a strategic joint venture between Baijin Group and Hubei Xingfa Group—successfully completed its annual surveillance audit for the ISO "Triple System" (ISO 9001:2015 Quality Management, ISO 14001:2015 Environmental Management, and ISO 45001:2018 Occupational Health and Safety Management). Conducted by China Merchants Testing and Certification (Chongqing) Co., Ltd., the audit team unanimously recommended the maintenance of all three certifications, marking a significant milestone in the facility’s commitment to international operational excellence and supply chain stability.
 

A Comprehensive "Physical Examination" of Operational Integrity

The two-day audit served as a rigorous "deep dive" into the facility’s entire business ecosystem, covering procurement, production manufacturing, safety and environmental control, and occupational health protection. This systematic review ensures that the high-volume production of Carbon Disulfide (CS2) and Dimethyl Sulfoxide (DMSO) at the Chongqing site continues to meet the stringent demands of global B2B procurement standards.

General Manager Xu Hougang emphasized the strategic importance of this process during the opening meeting: "This audit is effectively an annual 'physical examination' of our management system. It is imperative that all departments provide factual data and transparent documentation to ensure that our management remains standardized and robust."

Following the successful conclusion, Deputy General Manager Feng Tiejun reiterated the company's proactive stance: "Every audit is an opportunity to 'identify and fill gaps.' We do not view this merely as a certificate renewal, but as a chance to transform audit findings into actual management effectiveness and long-term operational resilience."
 

Technical Foundation: Anchoring Global Supply with Precision

The success of the ISO audit is built upon a foundation of advanced industrial infrastructure and strictly controlled technical assets. As a key node in Baijin Chemical’s global supply network, the Chongqing Xingfa Jinguan facility integrates high-capacity output with precision engineering.
 

Fixed Technical Assets and Production Specifications

The facility operates with a high degree of automation and technical rigor, ensuring that every batch of chemical product meets global industrial standards:

1. Subsidiary Capacity Foundation:

• Carbon Disulfide (CS2): Annual production capacity of 50,000 tons.
• Dimethyl Sulfoxide (DMSO): Annual production capacity of 20,000 tons.
• Dimethyl Sulfate (DMS): Annual production capacity of 16,000 tons.

2. Product Core Parameters (Storage A):

• DMSO (Dimethyl Sulfoxide): Features a purity range of 99.9% to 99.99%. Characterized by extreme solvency and high stability, the product is specifically engineered for pharmaceutical intermediates, semiconductor stripping fluids (electronic cleaning), and pesticide synergists.
• CS2 (Carbon Disulfide): Strictly adheres to the GB/T 1615-2008 national standard of the P.R. China. Key metrics include a distillation ratio of 98% minimum (at < 46.6°C), density between 1.262–1.265 at 20°C, and non-volatile content limited to ≤0.007%.

3. Advanced Automation and Control:

• DCS Centralized Control: The entire production sequence utilizes a DCS (Distributed Control System) remote central control system. This enables a fully closed-loop, continuous production process that ensures the safety, stability, and eco-friendly nature of the chemical synthesis.
   

Strategic Significance for Global B2B Partners

For international buyers in the pharmaceutical, electronics, and mining sectors, the maintenance of ISO Triple System certification at Chongqing Xingfa Jinguan is more than a regulatory formality—it is a guarantee of supply chain security.
 

1. Risk Mitigation in Hazardous Chemical Management

With over 30 years of expertise in the production, management, and project construction of dangerous chemicals (dating back to 1990), Baijin Group has woven safety into its organizational DNA. The ISO 45001 and ISO 14001 certifications validate the facility's ability to handle Class 8 and other hazardous materials with 99.98% total sulfur recovery rates, minimizing environmental impact and protecting workforce health.
 

2. Consistency in High-Purity Applications

The audit verified the facility's "Green Factory" and "High-tech Enterprise" credentials. For industries such as semiconductor manufacturing, where DMSO is used as a cleaning agent, or the pharmaceutical sector, where it acts as a reaction solvent, the ISO 9001 framework ensures that the 99.99% purity levels are consistent across every shipment.
 

3. Resilience Through Integrated Supply Chains

As a joint venture between Baijin Chemical—the global leader in CS2 with a 50% domestic market share—and Hubei Xingfa Group, the Chongqing facility benefits from an integrated sulfide chemical industrial chain. This synergy allows for the stable supply of raw materials even during global market fluctuations, a factor specifically praised by the audit team during their evaluation of the procurement and resource management sectors.
 

Conclusion: Driving the "Century-Old Golden Brand" Vision

The successful ISO audit at Chongqing Xingfa Jinguan reinforces Baijin Chemical’s broader mission of "Green Chemical Engineering, Beautiful Factory." By strictly adhering to international standards of quality, environmental stewardship, and occupational safety, the company continues to bridge the gap between industrial scale and sustainable manufacturing.

As Baijin Group continues to expand its global footprint—including its significant operations in India and five large-scale modern sulfide chemical factories across mainland China—the Chongqing facility stands as a benchmark for how standardized management and technical innovation can secure the future of the global sulfide chemical supply chain.
