Company Profile
On July 11, 2009, two senior project engineers crossed paths at an electronics factory in Dongguan city, China. By chance, they were seated together at lunch—and what started as a casual conversation quickly revealed a shared obsession: product engineering. That evening, instead of heading back to their respective companies, they continued their discussion and realized that the common administrative approach in the third-party inspection industry often neglected the technical substance required for true quality control. That night, China Quality Service (CNQ) was formed.
Since our founding, CNQ has upheld the core principles of independence, objectivity, and uncompromising professionalism. As a trusted provider of Product Inspection Service in China, we serve as our clients' eyes on the factory floor — with inspection networks across all major manufacturing hubs in China and Asia, mitigating supply chain risks and ensuring every shipment complies with global standards.
We conduct product inspections directly throughout China, backed by deep, on-the-ground manufacturing knowledge. We don’t just check boxes; we verify structural and functional compliance to understand the “how” behind the production, allowing us to spot issues standard inspectors miss.
Our services cover electronics, textiles, home products, toys & gifts, machinery, food contact materials and more, with clients across 50+ countries and regions including Europe, North America, Middle East and Southeast Asia.
We believe transparency is the best quality control tool. Beyond delivering hands-on quality control backed by 17 years of on-site expertise, we also collect and share insights from real-world manufacturing defects to help you mitigate potential pitfalls.
