The certification body and the product certificate

CQC stands for China Quality Certification Centre. Approved by the Chinese government, the organisation provides product certification, management system certification and related technical services. However, “a CQC certificate” is not a complete description: the issuing organisation and the certification scheme convey different information. Alongside voluntary CQC mark services, CQC carries out mandatory CCC certification within its designated scope.

The CQC mark is voluntary; CCC depends on the catalogue

CQC mark certification is a voluntary product certification service. Depending on the scheme, it can assess safety, performance, electromagnetic compatibility or other specified characteristics. A buyer may require the certificate as a purchasing condition, but that commercial requirement does not create the same legal obligation for every product.

CCC is China's compulsory product conformity system. Applicability depends on the current product catalogue and implementation rules. Where CCC applies, a voluntary CQC mark does not replace that obligation. Being outside the CCC scope does not mean that other legislation is irrelevant. The first step is correctly classifying the product's technical characteristics.

Which characteristics are assessed?

CQC's product scope extends from electronic products and components to cables, motors, lighting equipment and low-voltage apparatus. Do not assume that every product undergoes the same tests. The governing requirements are the standards and criteria identified in the relevant certification rule. Any relationship between Chinese national or industry standards and IEC standards must also be checked in the applicable document.

For example, EMC emissions and electrical safety are different assessments. CISPR 32 helps explain multimedia emissions, while the 55014 family addresses household appliance EMC. The IEC 61800 family provides technical frameworks for motor drives, and the 61010 family addresses safety for measurement and control equipment. These references cannot automatically replace the relevant Chinese implementation rule.

Environmental topics such as RoHS and hazardous substance restrictions may be covered by separate certification scopes. A safety certificate alone does not establish energy efficiency or compliance with every environmental requirement. Chinese energy or environmental certifications must also be assessed separately against other market rules, such as European ErP requirements.

Application, testing and production consistency

An application identifies the product model, manufacturer, production site, technical characteristics and critical components. Depending on the scheme, assessment may involve samples, type testing, factory inspection, a certification decision and subsequent surveillance. The scope of factory inspection and the surveillance method depend on the product and applicable rule; there is no single process template for every service.

ISO/IEC 17025 concerns the competence of testing and calibration laboratories. Acceptance of a laboratory report also depends on meeting the scheme's laboratory and testing requirements. An ISO 9001 certificate under the ISO management system framework assesses the organisation's quality management system; it does not replace CQC or CCC certification of a particular product.

If a certified drive's EMC filter, power component or enclosure changes, review the effect on its certified scope. Consistency between the tested sample and the manufactured product matters. Changes may require approval, additional testing or an update to the certificate's scope.

Reading validity and scope correctly

It is incorrect to state that every CQC certificate is valid for “3–5 years”. Check the validity period and maintenance conditions in the applicable certification rule and certificate. Alongside any printed expiry date, determine whether the certificate is valid, suspended, cancelled or withdrawn.

Compare the certificate number, holder, production site, covered models and applicable standards. A model outside a certified product family does not become covered simply because it uses a similar enclosure. During supplier assessment, check that the model on the product label matches the certificate. Verification through the official certificate enquiry service provides stronger evidence than relying solely on a PDF copy.

How international certificates relate

CQC also provides services under the IECEE CB Scheme. CB test reports and certificates can facilitate acceptance of test results in another certification application, but national differences, recognised scope and local requirements must still be assessed. A CB certificate is not an automatic worldwide sales authorisation.

Similarly, a CQC certificate does not directly replace CE marking, UL certification or the ETL mark. These operate under different legislation and certification arrangements. The useful goal is providing the evidence required by the destination market for the actual product, rather than simply collecting more certificates.
