Hedinger's headquarters have been located in Stuttgart, Germany since 1843. Also since 1843 is our core competence working with chemical products. At that early time, this competency was based on the best possible knowledge and belief, but for some time now, it has been based on international standards (i.e. quality, environmental, and occupational health and safety management systems) and strict compliance to global GMP guidelines. These aspects are so crucial for our business that we mention it here in our opening paragraph. (See also GMP menu item).
