Chemical Suppliers in Karachi
Khan Associates supplies industrial and laboratory chemicals, laboratory instruments and process monitoring equipment to businesses across Karachi from our office at Portway Trade Centre on Main Shahrah-e-Faisal. We have been importing and distributing since 1994, and we are the authorized Pakistan distributor for twelve international manufacturers.
If you are sourcing a process chemical, a laboratory instrument, or a treatment programme for an effluent plant, this page explains what we supply, how we work, and how to get a quotation.
Chemical Supply From Our Karachi Office
Our Karachi office is located at 908-909, 9th Floor Portway Trade Centre Plot # 189/A, S.M.C.H.S Main Shahrah-e-Faisal. It is a working office, not a mailing address, and it exists so that clients in Sindh have a local point of contact rather than dealing only with our Lahore corporate office.
Karachi’s industrial base is spread across SITE, Korangi, Landhi and Bin Qasim, and the requirements vary widely between them. A textile processing unit in Landhi has a different treatment problem to a pharmaceutical manufacturer in Korangi, and both are different again from a power plant at Port Qasim. Our role is to match the correct product and manufacturer to the specific application, rather than sell from a generic price list.
