About the Business Unit

WELDING still considers classic trade and distribution to be the foundation of its success today. Based in Hamburg, we are perpetuating the long-standing commercial tradition of this Hanseatic city predecessors. Since 1955, the company has been ensuring the reliable supply of active pharmaceutical ingredients to the human and veterinary pharmaceutical sectors. In its role as a service-oriented company, WELDING responds to the changing needs of its business partners. Over the years, additional business areas have therefore been established: finished drug development, registration and distribution, for example, has become a cornerstone of our company’s growth strategy. 

Stricter regulatory as well as qualitative requirements in the pharmaceutical industry demand not only quality assurance but also more stringent product documentation. WELDING is meeting the growing need for professional support in this area with services in both, quality assurance and regulatory affairs.
