DIN CERTCO is the certification organization of the TÜV Rheinland AG and DIN, the German Institute for Standardization e. V. DIN CERTCO monitors the quality assurance of down and feathers as well as their traceability.
Before the companies are allowed to use the Traumpass label for their products, they have to undergo a quality test and an audit. For these control measures, products of the specific producers are tested by accredited testing institutes. Filling materials used must comprise down and feathers that meet the requirements of the two highest quality classes of the European standard 12934; companies must submit correct declarations regarding filling composition.
Furthermore, the companies are audited at the production site: To fulfill this rule, an independent auditor visits the production site and checks the documentary traceability of the down and feathers used as filling. With the help of customs declarations, bills of delivery, and official tests results, the auditor can ascertain that the material does not come from live animals.
The certification must be renewed in strict time intervals. Additionally, finished products are constantly checked through mystery shopping and repeated onsite audits.
