GS Certification & GS Mark

⚠ CE Marking Gets Your Product into Europe. GS Mark Gets It onto the Shelves

CE marking is the legal floor, not the commercial ceiling. Major German and European retailers — particularly in the electrical and electronics category — routinely require GS Mark as a condition of listing. A product without GS Mark competing against one that has it starts at a disadvantage that no amount of pricing or marketing can fully overcome. In a market where buyers review supplier compliance portfolios before placing orders, the absence of a recognised safety mark above CE is itself a signal.

The gap between regulatory compliance and retail approval is wider than most manufacturers expect. Buyers at major retail chains and e-commerce platforms run their own compliance audits — CE clears the regulatory bar, but GS Mark certifies that your product has been independently verified to exceed it. Without that signal, you're asking a buyer to take your word for it. The ones who win German and EU retail accounts don't ask buyers to take their word — they have the mark.

GS Certification and GS Mark

The GS Mark, which stands for Geprüfte Sicherheit ("Tested Safety") is a voluntary certification scheme for technical equipment. Awarding of the GS Mark means that the product meets the safety requirements set out in the German Product Safety Act and, if applicable, relevant European safety standards. Moreover, the GS Mark certification requirements exceed those of the mandatory CE mark and the EN standard – meaning that products awarded the GS Mark exceed the required legal requirements for safety.

Although the GS Mark was initially designed for the German market, it is now a worldwide recognized mark of safety, and communicates to your customers that your product adheres to high standards.

GS Mark certification through QIMA covers the following electrical and electronic product categories — if your product type is listed, you're eligible to apply:

What GS Mark Certification Delivers

• Certification that exceeds CE — independently verified: GS Mark requirements go beyond both the mandatory CE mark and the applicable EN standards — meaning every product awarded the mark has been independently confirmed to exceed Europe's legal safety baseline, not just meet it. That's a claim your competitors cannot replicate without completing the same rigorous testing programme.

• The mark major EU retailers look for: German and European retail buyers increasingly require GS Mark as a condition of listing for electrical and electronic products — making it a commercial prerequisite, not just a quality signal. A GS Mark removes a potential objection at every retailer compliance review your product faces.

• Five-year validity with annual quality assurance built in: GS certification is valid for up to five years, with annual manufacturing site inspections confirming production consistency throughout. Your buyers know the mark reflects ongoing quality — not a one-time snapshot from a single test batch.

• Issued by a ZLS-authorised certification body: QIMA is authorised to award the GS Mark by the Zentralstelle der Länder für Sicherheitstechnik (ZLS) — Germany's official accreditation authority for certification bodies. Your GS Certificate is accepted by retailers, regulators, and customs authorities without challenge.

• Documented due diligence against product liability: Independent certification to a standard above CE provides third-party evidence of safety due diligence. In the event of a product incident, a GS Mark — backed by auditable test data — is a materially stronger position than CE self-declaration alone.

How to Get Your GS Mark

Step 1 — Define your product scope and target certification: Tell QIMA your product type and destination markets. Our engineers confirm which GS Mark product group applies — electrical products, lights and lamps, audio/video equipment, power supplies, or battery chargers — and identify the relevant EN standards and compliance requirements for your product. You receive a test plan and timeline before any samples are submitted.

Step 2 — Laboratory testing and compliance review: Your product undergoes prototype testing in QIMA's accredited laboratories against the applicable EN standards and the requirements of the German Product Safety Act. Testing covers functional performance, safety, and durability. Compliance documentation — including regulatory declarations — is reviewed alongside test results.

Step 3 — Annual manufacturing site inspection: As part of GS Mark certification, QIMA conducts an initial inspection of your manufacturing facility to verify production consistency with the tested prototype. Annual follow-up inspections are included throughout the certification's validity period — so your mark reflects ongoing production quality, not just a one-time sample.

Step 4 — Certificate issuance and mark awarded: If your product meets all requirements, QIMA issues your GS Certificate and you are authorised to display the GS Mark on your product and packaging. The certificate is valid for up to five years and is publicly listed in the QIMA certification database.

Step 5 — Renewal before expiry: QIMA notifies you ahead of your recertification window so your mark stays current without interruption. Recertification involves re-testing to confirm your product continues to meet the required standard — full or partial depending on whether the product or applicable standards have changed.

Frequently Asked Questions

1. How much does GS Mark certification cost?

Costs depend on your product type, the number of tests required, and whether a factory inspection is included in your certification scope. QIMA provides a scoping quote after reviewing your product details and target markets — share your information and you'll typically receive a quote within 24 hours.

2. How long does GS Mark certification take?

Most programmes are completed within 6–12 weeks from sample submission to certificate issuance, depending on product complexity and laboratory availability. If you have a launch or retailer deadline, share it when requesting a quote and we'll confirm whether the timeline is achievable.

3. I already have CE marking — do I also need GS Mark?

CE marking is a legal requirement for selling in the EU. GS Mark is a voluntary certification that exceeds it. If your goal is regulatory compliance alone, CE is sufficient. If your goal is retail listing in Germany and across Europe, GS Mark is what major buyers look for on top of CE. The two are complementary — CE gets your product through customs, GS Mark gets it onto shelves.

4. Which products can be GS Mark certified through QIMA?

QIMA is ZLS-authorised to certify the following product groups: electrical products with and without heating, electrical products with food contact, products with skin contact, lights and lamps, power supplies, battery chargers, and audio/video equipment. If you're unsure whether your product falls within scope, share the product details and our engineers will confirm.

5. What happens if my product fails testing?

You receive a detailed failure report identifying the exact test, the measured value, and the accepted limit. Our technical team can recommend corrective actions. Once you've made changes, we retest the failed items only — not the full battery. Most clients resolve first-time failures within one revision cycle.

6. What does the annual factory inspection involve?

Annual inspections verify that your manufacturing facility and production process remain consistent with the product that was originally tested and certified. QIMA's auditors visit your supplier's facility to review production controls, quality management, and any changes to materials or processes that could affect the certified product's safety profile.

7. Is GS Mark recognised outside Germany?

Yes. GS Mark originated as a German safety certification but is now recognised across Europe and by retailers and buyers in many international markets. It carries particular weight in Germany, Austria, and Switzerland, and is increasingly required by major EU retailers across all member states.
