NASCON Allied Industries Plc (previously National Salt Company of Nigeria Plc) was established in 1973 as a salt refinery at Ijoko (Near Sango-Ota); Ogun State as a joint venture between the Federal Military Government of Nigeria and Atlantic Salt & Chemical Inc. of Los Angeles, California, USA, due to an identified need for self-sufficiency in the production of this essential commodity.
In order to achieve this, the Federal Military Government appointed Messrs Atlantic Salt & Chemical Company Incorporation as Technical Partner for the establishment of this company in October 1972; the technical agreement was signed on March 1973. The National Salt Company of Nigeria was thus incorporated on April 30, 1973.The equity shareholding of the company at the time was:
- Federal Military Government of Nigeria 55%
- Atlantic Salt & Chemical Inc. 35% (Technical Partner)
- Former Western State Government 10% (Now Oyo, Ogun, Osun, Ondo, Lagos and Ekiti States)
The construction work commenced on October 20, 1974. Construction of the refinery was completed in December 1975 and erection of plants and machinery was completed in August 1976, with a total capacity of 110,00Mt. With the acquisition of controlling shares by Dangote Group, the average daily production increased to 600,000 metric tons per annum, with the inclusion of three refineries in Apapa, Oregun and Port Harcourt.
The production activity at the Apapa plant started in 2001 with the production of edible and kitchen salt in 25kg and 50 kg (bulk) sizes. The Port Harcourt refinery commenced production in 2003, while production at Oregun kicked off with the production of iodized table salt in 250g, 500g and 1Kg sachet sizes for domestic use under the brand names Annapurna®* and Dangote®.
