Lead Paragraph
In May 2026, Watersino successfully passed its ISO quality management system recertification audit and renewed its certification. Since first obtaining ISO certification in 2020, the company has continuously standardized its entire production and quality control process for six years. This recertification audit was passed with zero non-conformities, demonstrating that the company's production, quality inspection, and supply chain management fully comply with international standards. This further enhances its quality delivery capabilities and market competitiveness for high-end hotel clients in Europe, America, and Australia.
Standardized Management Measures
Long-term System Operation and Maintenance: After obtaining ISO certification for the first time in 2020, a normalized mechanism of annual full-process internal audits plus a three-year complete re-audit was established. Over six years, 24 rounds of internal system self-inspections were conducted, covering seven departments: R&D, procurement, machining, surface treatment, finished product testing, warehousing and logistics, and foreign trade after-sales service.
Production Hardware and Fixed Asset Support: Relying on a 7000㎡ standardized production plant in Jiangmen and a 2000㎡ product showroom in Guangzhou, a full set of quality inspection equipment, including water pressure and flow testing equipment and acid salt spray testing equipment, was invested in, continuously increasing investment in quality control hardware.
Multi-Certification Collaborative Management: The ISO system was integrated with mainstream European and American bathroom certifications such as Watermark, WELS, WRAS, and UPC, unifying raw material access standards, mandating the use of DZR low-lead brass and 304 stainless steel compliant base materials, and establishing a material traceability ledger.
Standardized Process Flow: Sixteen documented production processes for all hardware and bathroom fixtures are standardized, from raw material sampling and inspection upon arrival, CNC precision casting, wire drawing/electroplating surface treatment, sealing testing, flow rate detection, acid salt spray testing to finished product packaging. Traceable records are maintained for each process.
Quantitative Quality Inspection Standards: Finished products undergo 100% hydrostatic testing and 48-hour acid salt spray testing before leaving the factory. The batch pass rate of raw materials is included in the system's performance evaluation. Non-conforming materials undergo a closed-loop process of isolation, rework, and traceability.
Highlights & Innovative Practices
Innovative Digital Implementation of the System: An online system document management library was established, allowing production, quality control, and foreign trade personnel to access ISO standard operating procedures in real time. Audit and testing records are archived online, significantly improving the efficiency of document retrieval and on-site verification for audits. The efficiency of document delivery for this external audit improved by 60%.
Proactive Integration of Customer Needs into the System: Customized standards for overseas major clients' hotels and European and American low-flow water conservation specifications were embedded into ISO management documents. Design, production, and inspection specifications were updated simultaneously, achieving integrated management of international standards and customer-customized requirements.
Zero Flaws in On-Site Audit Performance: In May 2026, a third-party certification body conducted a 3-day on-site audit, verifying the entire chain of workshop production, laboratory testing records, supply chain ledgers, and customer complaint handling. No major or minor non-conformities were found throughout the process, earning high praise from the audit team.
Internal Improvements & Advantages for Global Clients
Significantly Improved Production Efficiency and Quality: Compared to the initial certification in 2020, the product defect rate decreased by 72%, and the on-time delivery rate for customized orders remained stable at over 98.5%. Internal processes were also streamlined and more efficient.
Lowered Barriers to Customer Cooperation: Valid ISO certification is a core entry requirement for procurement in overseas high-end markets and five-star hotels. Renewal of certification directly meets customer factory audit requirements, significantly shortening the cooperation cycle.
Enhanced Overseas Brand Strength: The standardized quality management system facilitates market expansion in Europe, America, and Oceania, leading to a continuous increase in the number of high-end B2B clients.
More Reliable After-Sales Support: The full-process traceability system allows for rapid identification of product issues, ensuring efficient after-sales response and effectively reducing the risk of customer quality complaints.
Background Information
The global bathroom industry continues to raise the bar for international standardization qualifications for supply chain companies. ISO quality management system certification is a fundamental entry credential for cross-border B2B cooperation. Since its inception, the company has adhered to the development philosophy that "Quality Is The Life of The Enterprise." After obtaining its first certification in 2020, it has continuously deepened the implementation of its system. This renewal certification is a core guarantee for the brand to adapt to the rules of the global high-end bathroom supply chain and continuously provide compliant, high-quality products to overseas high-quality customers.
Conclusion
The successful renewal of the ISO certification in 2026 is a comprehensive recognition by authoritative institutions of Watersino's six years of standardized quality management achievements. It serves as both a cornerstone of the company's commitment to quality in the high-end cross-border bathroom fixture market and a powerful fulfillment of its quality promises to global partners. Moving forward, the company will continue to iterate its ISO management system, simultaneously integrating environmental protection and occupational health management standards to upgrade its comprehensive control; increase investment in water-saving technologies and low-lead environmentally friendly new materials research and development; and continuously optimize its automated quality inspection production lines. With a higher standard of international management, the company will support its global market expansion and provide more stable, compliant, and high-quality integrated bathroom hardware solutions for overseas projects and hotel customization clients.
