About reminding certified customers to guard against fraudulent announcements
Recently, our center has received many reports about the following issues:
1. Individual organizations or individuals in the name of our center, or claiming to be instructed by our center, send CCC certificate suspension recovery notice, cancellation cost notice, and certificate extension fee notification to our center's customers.
Secondly, individual agencies link to our center's website without authorization on their websites, and declare that they have "a good cooperation relationship with CQC", "can use a flexible process to complete certification", "can be used for business, as soon as possible to obtain certification" and so on.
The above two acts have seriously damaged the reputation of our center, damaged the seriousness of the compulsory product certification system, and the rights of the majority of certified organizations have also been exposed to the risk of illegal infringement. In view of this, our center solemnly declares:
1. Our center has not instructed any intermediary, agency and consulting agency to carry out business activities related to certification.
Second, our center has not established any partnership with any certification intermediary, agency and consulting agency.
3. Our center has never commissioned any intermediary, agency, or consulting agency to collect fees related to certification. There will be no such delegation in the future.
If the certified organization or the relevant organization encounters the above situation, please pay attention to avoid being deceived. If you need to apply for certification, please contact the relevant department or branch of our center. Please contact our website (.com.cn) for specific contact information.
Please pay attention to the relevant information released by our center on the website and business system customer interface. If you have any questions, please immediately check with our center and call our customer service center.

For a long time, some unscrupulous organizations and individuals in the society assumed the name of the China Quality Certification Center (CQC) and solicited business from certified companies. These included notifications of suspension of CCC certificates, notices of write-off costs, notifications of delays in certificates, and other serious violations of product certification management. Procedures and business interests. To this end, the China Quality Certification Center issued an announcement a few days ago and solemnly reminded the certification companies to guard against fraud. The full text of the "Announcement" follows.
