What Is the Certificate?
The GS mark (Geprüfte Sicherheit — tested safety) is a voluntary safety mark based on the German Product Safety Act (ProdSG). An authorised body tests the product, audits the production site, and licenses use of the mark. It has a strong position for consumer trust in the German market, and retail chains often require it.
Who Needs It?
- Manufacturers selling into the German and Central European market
- Manufacturers of electrical household appliances, power tools and garden products
- Manufacturers of furniture, toys and sports equipment
- Firms supplying German retail chains
Is It Mandatory?
Not legally mandatory; voluntary. However, German retailers and public procurement often make the GS mark a precondition, which turns it into an effective market-entry requirement. Use of the GS mark is time-limited and is maintained through factory audits.
Scope of the Standard
- Type testing against the relevant product standard and ProdSG requirements
- Assessment of the instructions for use in German
- Ergonomics and user-safety assessment
- Checking chemical-substance requirements (e.g. PAH)
- A factory audit and assessment of the production control system
- Licensing the GS mark and using it together with the authorised body's logo
- Annual surveillance audits and market-sample checks
Certification Process
- 1Application and Product DescriptionThe product family, model list, technical specifications and target market are determined. The applicable standard and certification route become clear at this step.
- 2Technical File ReviewDesign documents, the bill of materials, critical-component certificates and the instructions for use are examined.
- 3Product TestingThe tests the relevant standard requires are carried out. The test report is the fundamental basis for the certification decision.
- 4Factory AuditIf the scheme requires it, the continuity of manufacturing and factory production control (FPC) are verified on site.
- 5Issuing the Certificate and MarkingOnce conformity is verified, the certificate is issued; the marking rules for the product and packaging are applied.
- 6Follow-up AuditsDepending on the scheme, periodic factory audits and/or follow-up testing on samples taken from the market are carried out.
Period of Validity
The validity period varies by scheme: some product certificates are indefinite and rely on periodic factory audits, while some schemes (e.g. country market marks) require annual or per-shipment renewal. Every design change to the product requires the certificate to be reviewed.
Required Documents
- The list of product models and variants
- Technical drawings, diagrams and the bill of materials
- Certificates for critical components
- The instructions for use and a sample label
- Existing test reports, if any
- Production-site details
Certification Cost
There is no fixed list price; the cost is calculated based on the following variables and provided in writing in the quote.
- The number of models and variants in the product family
- The test scope the applicable standard requires
- Whether a factory audit is required
- The number of target markets and whether each requires separate testing
- Whether existing test reports can be accepted
Accreditation
Product certification is carried out under ISO/IEC 17065; The tests that form the basis for certification are carried out in laboratories with ISO/IEC 17025 accreditation. The two scopes are separate. Recognition between accreditation bodies is provided through IAF and ILAC agreements.
The scope under which this scheme can be offered varies according to your product and activity; it is confirmed in writing at the quote stage.

Frequently Asked Questions
How many years is a GS certificate valid?
The licence is granted for a set period and requires regular factory audits to be maintained. If auditing does not take place, the right to use the mark ends.
Why is a PAH test requested for my product for GS?
The GS scheme includes polycyclic aromatic hydrocarbon (PAH) limits for plastic and rubber parts in skin contact. This is an additional GS requirement not otherwise required under CE.
