About Us
Connected worldwide.
By your side, personally.
Inter-Harz operates in chemical distribution worldwide, always staying close to suppliers and customers. What began in 1993 with four employees has grown into an international distribution company with around 50 employees and three of its own office complexes.
More than 2,000 raw materials available worldwide.
Through four contract warehouses, Inter-Harz supplies customers worldwide with more than 2,000 raw materials. We trade in our own name and deliver exclusively original manufacturer qualities in original packaging.
Short paths for fast decisions.
We deliberately avoid complex structures and lengthy procurement processes. Through direct communication, short decision-making paths, and close coordination with customers and partners, we respond flexibly to requirements along the supply chain. This is how we create efficient solutions and a reliable supply of raw materials.

„We organize the entire supply chain and take responsibility for every part of it. Our work is built on personalized service, reliable partnerships, and collaboration you can count on.“
