Background

Usiminas (Usinas Siderurgicas de Minas Gerais SA) is Brazil's leading producer of flat steel, with access to 2.6 billion tons of iron ore reserves. The company began steel making operations in 1962 at its Usiminas Ipatinga steel plant in the mineral-rich state of Minas Gerais and subsequently acquired the Cubatão plant in 1993. The company produces uncoated flat steel (plates, thick plates, hot and cold rolled), with customers in the railway, automotive, naval, agricultural, and civil construction sectors, among others.

The Cubatão steel plant traces its origins to 1953, when a group of Brazilian engineers founded COSIPA (Companhia Siderúrgica Paulista) with the goal of constructing a São Paulo-based steel plant to rival the thriving new Presidente Vargas Steelworks in Volta Redonda. The project was initially launched with private capital, but its ambitious scope led to significant delays, and government investment was eventually required to ensure the plant's completion in December 1963. State ownership of the project rose from 58% in 1961 to 98.6% in 1970.

The COSIPA plant grew steadily over its first three decades of operation, opening its own maritime terminal in 1969 and increasing production capacity from an initial level of 600,000 tpa in 1965 to 3.9 million tpa with the inauguration of the plant's second blast furnace in 1976.

On August 20, 1993 COSIPA was privatized via an auction on the São Paulo Stock Exchange (BOVESPA), with a group of investors led by Usiminas taking control of the company. The new owners embarked on a campaign to modernize the plant, refurbishing blast furnace #2 and adding a new steel making facility in 2001 and taking several other measures to improve the plant's efficiency over the next decade.

Amidst Brazil's financial crisis in October 2015, Usiminas announced that it was halting steel production at the Cubatão plant, with closure of the plant's two blast furnaces, coke plant and sintering plant. The thousands of resulting layoffs significantly impacted the local economy; however, operations continued at the plant's hot rolling and cold rolling lines, and at the hot strip mill.

In April 2019, citing continued weakness in the Brazilian economy, Usiminas announced that steel production at the Cubatão plant would not resume until 2022 at the earliest. Subsequent reporting from Reuters in February 2020 indicated that steelmaking was unlikely to resume before 2024. In April 2020, operations at the plant's rolling mill were also suspended after Covid-19 shut down Brazil's auto-making industry, prompting a precipitous dropoff in demand for finished steel.

In August 2022, Usiminas's board president Sergio Leite de Andrade confirmed that the company planned to resume crude steel production at the Cubatão plant, but he offered no target date, and noted that the eventual resumption of operations would be contingent upon adoption of new carbon neutral technology at the plant, such as biochar-based self-reduction pellets.

Usiminas's 2022 annual sustainability report, released in July 2023, attributed the company's entire 2022 crude steel production (2.7 million tonnes) to Usiminas's Ipatinga plant, implying that the Cubatão plant did not produce any crude steel in 2022. As of Q2 2023, Ipatinga still appeared to be the only Usiminas unit producing crude steel, with the Cubatão plant exclusively focused on finished steel production.

As of December 2023, the Cubatão plant did not appear to have resumed steelmaking operations.

When steelmaking operations start up again, Cubatão's output is initially projected to be between 1 and 1.2 million tonnes per annum, well shy of its 4 million tpa capacity.
