The mineral industry of Paraguay produces about 25% of the country's gross domestic product (GDP) and employs about 31% of the labor force. Production of cement, iron ore, and steel occurs commonly throughout Paraguay's industrial sector. The growth of the industry was further fueled by the maquila industry, with large industrial complexes located in the eastern part of the country. Paraguay put in place many incentives aimed to attract industries to the country. One of them is the so-called "Maquila law" by which companies can relocate to Paraguay, enjoying minimal tax rates.
