I. Domestic Certification Verification
Unified domestic certification inquiry. According to market regulatory guidelines, all valid certification certificates can be verified via the National Public Service Platform for Certification and Accreditation Information (Ren-e-Yun: cx.cnca.cn).
Users can enter the certificate number or company name to check authenticity and validity. Mandatory Product Certification (CCC) certificates can also be verified in the “Mandatory Product Certification” section of the platform. The platform hosts over 4.22 million certificates and data on 1.13 million certified enterprises; if a certificate cannot be found there, it is invalid.
II. Overseas Certification Channels
Overseas certification verification channels.
Industry guidelines state that CE certificates must be issued by EU-authorized Notified Bodies;
verification involves visiting the Notified Body’s official website and entering the manufacturer’s English name and certificate number to find matching records. UL certifications can be searched via the UL Product iQ database, while ISO system certificates can be cross-verified using the IAF CertSearch international database. Certificates displaying only the CB mark without an accreditation body logo, or those with incorrect certificate number formats, are likely counterfeit.
III.
Verification of Certificate Details
Verifying certification certificate details.
Industry best practices dictate that a legitimate ISO 9001 certificate must include: the standard version (ISO 9001:2015); the issuing body’s name and logo; the accreditation body’s logo (e.g., UKAS, JAS-ANZ, ANAB) and accreditation number; a unique certificate number; and the validity period (typically a three-year cycle with annual surveillance audits). Companies cannot self-declare certification; certificates lacking the logo of an independent third-party registrar are invalid.
Furthermore, the certification scope must cover the specific category of the purchased product.
IV. Key Points of Test Reports
How to interpret inspection and test reports.
According to market regulation guidelines, a valid report must include: the testing agency’s name, address, contact details, and qualification certificate number; the sample’s name, specifications, condition, and unique identification number; the testing standards applied; a clear conclusion and date of issuance; and the signatures or seals of the testing personnel, reviewers, and approvers.
Reports lacking the official inspection/testing seal, showing signs of alteration, or missing the required signatures/seals for testing, review, and approval will not be recognized.
V.
Verifying Report Authenticity
Channels for verifying report authenticity: Based on industry practice, reports can be verified in four ways: calling the issuing agency’s official phone number; visiting the agency in person; querying the report number on the agency’s official website; or scanning the report’s QR code to access the verification page (ensure the link leads to the agency’s official site). Additionally, one can check the agency’s qualifications on the market regulator’s official website and cross-reference the product name, model, and batch number with the actual item.
Suspected fraudulent reports should be reported via the 12315 platform.
Conclusion
How should one evaluate quality certification for automation components? The conclusion lies in the “three-check” method: check the platform, check the report, and check the details. For domestic certifications, use the CNCA platform (cx.cnca.cn) to query certificate numbers—covering both 3C and ISO systems. For overseas certifications, consult the websites of CE Notified Bodies, UL Product iQ, or the IAF CertSearch international database. Regarding inspection reports, verify the agency’s qualification number, the sample’s unique ID, the testing standards, the three required signatures/seals, and the report’s unique ID.
Per industry practice, China RoHS conformity assessments can be checked on the Ministry of Industry and Information Technology’s public service platform (chinarohs.miit.gov.cn); as of the end of 2025, this database included over 1,400 enterprises and more than 20,000 conformity assessment records covering over 30,000 products. Certification is not merely ink on paper; it must be verifiable on official platforms.
Inability to locate the record, scope mismatches, or irregular numbering formats are all red flags.
