The quality of our services and products is essential for us. We therefore have been intensively involved in the quality management and analysis through our subsidiary GMA (Gesellschaft für Mineralöl-Analytik und Qualitätsmanagement). GMA operates an own laboratory, accredited by DACH (Deutsche Akkreditierungsstelle Chemie GmbH).


GMA’s services include quality control of automotive fuels, biogenous fuels, heating oils and advice on applications. In addition, GMA is committed to further developing product standards, in particular through cooperation with national and international standardization committees. The services also focus on giving advice regarding fuel additives. In accordance with the customer’s needs, and in cooperation with manufacturers, customized additives are developed and provided to the Marquard & Bahls group companies and for external clients.

GMA regularly produces and distributes material safety data sheets for internal and external customers. Our range of activities is rounded off by organizing training courses in aforementioned subjects.

GMA’s services have especially been developed to meet the demands of the oil trading and tank terminal business. The increasing number of external customers proves the company’s efficiency and attractiveness.
