The German automotive association (VDA), which holds the AdBlue trademark and is responsible for certifying AdBlue suppliers, has approved Zaklady Chemiczne "Police" and HOYER Group under its new audit programme. German-based distributor HOYER Group boasts a network which handles over 100k tonnes of AdBlue a year, while AdBlue manufacturer Police supplies customers in both Poland and neighbouring countries. The VDA made it compulsory for all new members to undergo audits before they can become approved suppliers and use the AdBlue trademark in October last year, and is encouraging existing licensees to take part in the tests.
