Ittehad Chemicals Limited is one of the largest manufacturers of industrial chemicals that produces Caustic Soda, Liquid Chlorine, Hydrochloric Acid, Sodium Hypochlorite, Bleaching Earth (Shaffaf), Sulphuric Acid Commercial and Zinc Sulphate which are consumed in Textile, Soap, Paper, Fertilizers, Power Generation, Metal, Vegetable Oil and Ghee, Agriculture, Beverages and host of other industries of the country.

Ittehad Chemicals Limited, previously known as United Chemicals, was established in 1964 by a private entrepreneurial group with a capacity of 60 Metric Tons of Caustic Soda per day, which was subsequently enhanced to 90 Metric Tons per day in 1969. The project was nationalized in 1972 and production capacity of Caustic Soda was further increased to 150 Metric Tons per day in 1983.

After the privatisation, the production capacity of Caustic Soda was increased to 190 Metric Tons per day through indigenous arrangements, debottlenecking and addition of equipment, which helped feed its Clientele in a better way.

In September 2003, another addition of 163 Metric Tons of Caustic Soda per day had been made, based on the latest and state of the art, ion exchange membrane technology, thus totaling the capacity as 350 Metric Tons per day of Caustic Soda and 315 Metric Tons of Chlorine. This has been done to confront the challenges, posing to industry, when WTO regime becomes fully operative.

Ittehad Chemicals Limited was privatized in July 1995. The company is now owned by a very dynamic and forward looking enterprising group known as Chemi Group of Industries. The plant is being run very efficiently through the efforts of most competent and experienced engineers, skilled supervisors and workers, thereby contributing a lot, not only for the well being of the country, but also saving huge foreign exchange and providing jobs to about 1000 people.

The new management is actively busy in upgrading the plant conditions which were very poor in the state-owned period, by renovating the plant machinery and with addition of new equipment, incurring huge expenditures. All such measures are yielding results with sustained and reliable flow of the industrial chemicals to the market as well as to other very vital consuming industries.
