Tanjin Carbon is pleased to confirm the successful renewal of our ISO 9001:2015 certification following a comprehensive audit conducted by an accredited third-party certification body. This renewal reflects our ongoing dedication to maintaining robust quality management systems across all areas of our operations.
Audit Results
The external audit team evaluated our production processes, supply chain management, customer service procedures, and documentation practices over a five-day assessment period. Tanjin Carbon passed with zero major non-conformities, and auditors noted several areas of best practice, particularly in our raw material traceability systems and our approach to continuous improvement through employee feedback programs.
Why Certification Matters
ISO 9001 certification provides our customers with independent verification that our quality management systems meet internationally recognized standards. For clients in regulated industries such as municipal water treatment and food-grade applications, this certification is often a prerequisite for supplier qualification. It assures buyers that our processes are consistent, documented, and subject to regular review.
Continuous Improvement
Beyond maintaining certification, Tanjin Carbon uses the ISO framework as a foundation for continuous improvement. Each year we set measurable quality objectives and track performance against them. This disciplined approach has helped us reduce defect rates by 30% over the past three years while improving on-time delivery performance to above 97%.
