130 years of tradition with steady innovation and solid growth have made HOK a leader in cotton byproduct trade. We are a medium sized, family-owned company. We attach great importance to long term partnerships and direct contact with our customers.
Through many years of international trade, we have established excellent business relationships with suppliers of diverse textile raw materials on all continents. We can therefore offer you an extensive range.
The flow of goods runs almost exclusively through our own warehouses in Grevenbroich-Kapellen, where we also have laboratory facilities. Each shipment is checked and processed to the highest standards.
As an active member of the Bremen Cotton Exchange for more than 50 years we are always in tune with the latest developments in the cotton market and fibre technology.
