In SCR systems (SCR=selective catalytic reduction), the chemical synthesis product urea AUS 32 (AdBlue®) is used to reduce NOx exhaust gases. For the worldwide distribution of urea AUS 32, the VDA has registered the trademark “AdBlue®” in all relevant automotive markets.
The licensees of the VDA have invested considerable amounts in order to be able to produce AdBlue® in the required quality (ISO 22241). Furthermore, they are obliged to monitor their distribution chain and ensure that AdBlue® is not contaminated with other substances during transport – e.g. by decanting into smaller containers.Infoflyer download
In some cases, however, AdBlue® is offered in a quality that does not comply with ISO and, in the worst case, can lead to failure of the SCR system. In some cases, a substance is offered that is called AdBlue® , but without ever having concluded a license agreement with the VDA. The end consumer can therefore not rely on the information provided by individual distributors, because no one has ever controlled the market.
The VDA QMC has therefore drawn up a set of rules for auditing and certifying the manufacturers and distributors of AdBlue® and, on this basis, coordinates all audit activities relating to AdBlue® worldwide.Explanations of the AdBlue® brand

The VDA only grants an AdBlue® license to manufacturers. Dealers cannot obtain their own license from the VDA. However, licensed manufacturers are entitled to issue a sub-license to certain customers; e.g. with the aim that ARAL may offer AdBlue on the market as “ARAL-AdBlue” without manufacturing the product itself.
