Uzbekistan's industrial sector accounted for 33 percent of its NMP in 1991. Despite some efforts to diversify its industrial base, industry remains dominated by raw materials extraction and processing, most of which is connected with cotton production and minerals. Uzbekistan's most productive heavy industries have been extraction of natural gas and oil; oil refining; mining and mineral processing; machine building, especially equipment for cotton cultivation and the textile industry; coal mining; and the ferrous metallurgy, chemical, and electrical power industries. The chemical manufacturing industry focuses primarily on the production of fertilizer.

Two oil refineries in Uzbekistan, located at Farghona and Amtiari, have a combined capacity of 173,000 barrels per day. Other centers of the processing industries include Angren (for coal), Bekobod (steel), Olmaliq (copper, zinc, and molybdenum), Zarafshon (gold), and Yangiobod (uranium). The Uzbek fertilizer industry was established at Chirchiq, northeast of Tashkent, near Samarqand, and at several sites in the Fergana Basin. Uzbekistan is the largest producer of machinery for all phases of cotton cultivation and processing, as well as for irrigation, in the former Soviet Union. The machine building industry is centered at Tashkent, Chirchiq, Samarqand, and Andijon in the east, and at Nukus in Karakalpakstan.
