TÜV-GS

The GS or "Geprüfte Sicherheit" (proven safety) mark is a voluntary certification based on the law for the safety of products (ProdSG) in force in Germany and certifies the conformity of a product with safety standards valid both in the same country and in Europe.

Recognized globally even in the supply chain, as is the case with TÜV SÜD, the GS mark is awarded on completion of the relevant program of testing and inspection and remains valid as long as a production control inspection is performed every year.

Even in this case, obtaining the mark GS demonstrates a company's commitment to safeguarding the health of consumers and increases the reliability of its products.
