Founded in 2014 by Michael Hanzl, Sostie developed quickly to one of the most reliable and experienced companies for sourcing in Europe. From this we encouraged our partners to outsource production with and without technical package to partner companies of Sostie. We evolved to the point where we are sourcing chemicals, mainly in EU, but also with our subsidiary in USA and with our partners in China. More than this, we can offer from stock interesting chemicals for many applications. Please find out in our section "products"
