INTERDARM is founded in Rotterdam, The Netherlands by Niko C. Anastasyadis, a Greek businessman who carries on the family tradition of processing and selling natural casings, now in its third generation. Rotterdam is chosen as headquarters because of the important location as port of entry for natural casings into Europe.

Business contacts with Mongolia are set up. This first visit will form the foundation for a strong and special partnership that lasts to this day.

The son, also named Niko Anastasyadis, joins the family business and over the years, he will develop himself as a technical expert for sheep casings and becoming a valuable asset to the company.

Niko Anastasyadis takes over his fatherĀ“s position as Managing Director in the company.

A mobile processing facility, built inside a 40ft container in The Netherlands, is installed in Ulaanbaatar, Mongolia. In the next years, it will function as a training center for handling, processing and preserving sheep casings. Uniform standard specifications for raw material are introduced, that are still used today.

An 850 m2 production facility is opened in Ulaanbaatar, Mongolia. This new facility enables all Mongolian raw material to be processed locally, instead of exporting it for processing.

Niko jr. follows in the footsteps of his father and grandfather and joins INTERDARM.

Opening of a new, 3.800m2 production facility in Ulaanbaatar, Mongolia which is built to the latest standards in hygiene, infrastructure and efficiency.



People play an important role in our organization. INTERDARM natural casings are completely handmade by our skilled staff, who put their dedication into the final product every day. Our experienced selectors calibrate up to 8.000 meters every day!

But even with our highly motivated team, we cannot be successful all by ourselves. We place great value on the long-term partnerships we have built up in Poland, Egypt, China and New-Zealand. They play a key part in achieving a consistent, high product quality.



We manage our operations from our headquarters in The Netherlands. Our production facility is based in Ulaanbaatar, Mongolia. This modern factory with 3.800m2 working area enables us to have full control over the entire production process under one roof.

The building infrastructure allows for completely separate workflows, ensuring product control and full traceability. Modern freezing and cooling facilities help control the optimal climate for our product in the different production stages.

Through an optimized logistics and distribution network in Europe, we are able to supply our customers with short delivery times.
