Company
we are…
John A. Mason GmbH & Co. KG, founded in 1938, a third-generation, family-run and owner-managed, internationally successful foreign trade company based in Hamburg, Germany. Since the takeover by Hans Sassenberg in 1964, we have specialized in individually tailored trading solutions. Over the years, we have steadily expanded our product portfolio and since then have traded a wide range of pharmaceutical and cosmetic raw materials, food and feed ingredients as well as numerous industrial chemicals.
Today, Andreas Sassenberg and his son Matthias Sassenberg manage the company, supported by an experienced team of well-versed wholesale and foreign trade, shipping and forwarding agents as well as qualified dangerous goods officers and international foreign language correspondents. With a portfolio of over 600 products and more than 250 satisfied customers in over 28 countries worldwide, we are constantly growing and developing.
