In 2007 we decided to start ICG Specialty Chemicals selling specialty chemicals and additives under the tradename Omnistab.



Partners in Chemicals expanded its business in Middle East by setting up a branch office in Dubai in 2014.

Our Dubai office gives direct access to the Middle East and Africa. Having warehousing facility in the Dubai Free Zone makes it much easier to import, stock and re-export material to different destinations around the globe.




To serve the American market we have set up our Chicago branch office in 2009.
