A GB standard and CCC certification are not the same thing. A GB standard sets technical requirements or methods. China Compulsory Certification (CCC) is a regulated conformity-assessment system for products within the current compulsory-certification catalogue, carried out under product-specific implementation rules. A product may have relevant GB standards without being in the CCC catalogue, while a catalogue product usually requires more than a claim that it “meets GB.”
This guide is for overseas buyers, manufacturers and technical teams deciding what evidence to request. It is an operational checklist, not a product classification ruling, certification service or legal opinion. Confirm the current catalogue and implementation rule with the responsible Chinese authority or designated certification body.
1. Keep the four document types separate
| Item | What it does | What it does not prove by itself |
|---|---|---|
| GB standard | States technical requirements, test methods or other standardized content. | That the product is in the CCC catalogue or has been certified. |
| Test report | Records testing of identified samples against a stated scope and edition. | That a certificate exists, remains valid or covers the production model. |
| CCC certificate or accepted declaration | Records a conformity-assessment result under the applicable scheme. | That every model, configuration or later change is automatically covered. |
| CCC mark | Shows use of the compulsory-certification mark under the applicable requirements. | Certificate scope, status and product identity without verification. |
The distinction matters in purchase orders. “Comply with GB XXXX” describes a technical basis; “CCC required” introduces a catalogue and certification-rule question. Neither phrase is complete unless the product scope, edition and evidence are identified.
2. Decide whether the product is in the current CCC catalogue
The SAMR certification regulation says that products subject to compulsory certification are managed through a unified catalogue. The catalogue is adjusted over time. Do not infer CCC status from a product's voltage, a competitor's certificate, an HS code or the existence of a mandatory GB standard alone.
- Write the product name, intended use, main function and key technical boundaries.
- Check the latest catalogue description and boundary definitions on the CNCA CCC portal.
- Open the implementation rule for the matched product category.
- Confirm ambiguous or multifunction products with a designated certification body or competent authority.
- Record the source, rule number, version and check date.
As of the CNCA summary updated in August 2026, the catalogue is described as 17 major categories and 106 product types. Treat those figures as a dated snapshot, not a permanent shortcut. The product description and current rule control the decision.
3. Read the implementation rule, not only the GB number
Under the SAMR regulation, an implementation rule includes the product scope, applicable standards or mandatory technical requirements, certification mode, application-unit principles, sampling, testing, factory inspection, follow-up inspection, certificate validity and marking requirements. Buying the cited GB document helps the technical team, but it does not perform these other steps.
Use the current CNCA implementation-rule summary to find the rule for the product category. Then make a rule-to-evidence matrix with: requirement source; product model; sample or production evidence; responsible party; certificate or declaration reference; unresolved gap.
Standards can also be revised while a certification project is active. A publication date, implementation date and certification transition date are related but not interchangeable. Ask the certification body which edition and transition arrangement applies to the application and existing certificate.
4. Check the certification mode and transition dates
CCC does not use one unchanging process for every product. Certification modes can include design appraisal, type testing, sampling, factory quality-assurance checks and follow-up surveillance, alone or in combination. Current product rules determine the required path.
A recent example shows why dated checks matter. SAMR Announcement 2025 No. 57, published on 7 January 2026, changes 16 product types from a self-declaration route to third-party certification. Certification bodies began accepting applications on 1 July 2026, and affected businesses must complete certificate conversion by 31 December 2026 before the new requirement applies on 1 January 2027.
This example is not a general deadline for all products. It shows that buyers should record the exact announcement and product type instead of repeating “CCC required” without a date or scheme.
5. Verify evidence at product-model level
When a supplier claims CCC coverage, request enough information to verify the certificate or declaration through the official public-query route. Match the product name, model or series, applicant, manufacturer, production site where applicable, certification basis and status. A logo image or cropped certificate page is not sufficient evidence.
- Confirm that the supplied model falls inside the listed scope.
- Check whether the certificate is valid, suspended, cancelled or withdrawn.
- Compare key components and configurations against the certified documentation.
- Record any product, factory or standard changes that may require a certificate update.
- Keep the verification date and source with the purchase record.
A test report should be linked to the same product identity and edition. It can support the file, but the regulation also includes application, certification decision, production consistency and follow-up controls. Do not substitute one report for the complete scheme.
6. Write a purchase requirement that can be checked
A useful purchase request separates technical and certification evidence:
- Product name, intended use, model, configuration and production site.
- Applicable CCC catalogue category and implementation-rule number, version and check date.
- Applicable GB or other technical standards with full identifiers and years.
- Required certificate or declaration number and official verification route.
- Test-report scope, sample identity, issuing body and edition.
- Marking, packaging and document-delivery requirements.
- Change-notification obligations for model, key parts, factory, standard or certificate status.
- Owner and deadline for unresolved classification questions.
Use the GB and GB/T guide to understand the prefix before buying documents, and the search workflow to locate the exact standard named by the implementation rule. China Standards Hub supplies standard-document search and sourcing; it is not a CCC certification body.
7. Avoid four common conclusions
- “There is a mandatory GB, so CCC must apply.” Catalogue scope and the implementation rule must still be checked.
- “The product passed a GB test, so it is CCC certified.” Testing is only one possible element of the certification process.
- “A CCC mark proves every supplied model is covered.” Verify certificate status and scope against the actual model.
- “Last year's product list is enough.” Catalogue boundaries, rules and certification modes can change.
Frequently asked questions
Does every product covered by a GB standard need CCC certification?
No. CCC applicability depends on whether the product falls within the current compulsory-certification catalogue and its boundary definitions. The relevant implementation rule then identifies the certification basis and process.
Is a GB test report the same as a CCC certificate?
No. A test report records testing for identified samples and scope. CCC can also involve application review, production consistency, factory checks, certification decisions, marking and follow-up surveillance under the applicable rule.
Can buyers rely on a supplier's CCC logo?
No. Obtain the certificate or declaration details and verify status and scope through the official query service. Match the actual model, applicant, manufacturer and other relevant identity fields before accepting the claim.
Once the implementation rule identifies the technical documents, browse the GB standards directory using complete codes and editions. Keep the catalogue decision, rule, standard and evidence as separate linked records.
