Exports Up, Home Market Down: The New Reality For Brazil’s Steel Sector

Brazil’s steel sector is juggling weak domestic demand, aggressive foreign competition and shifting trade barriers, even as mills keep furnaces running.

In October, crude steel output slipped 2.7% from a year earlier but rose 6.1% versus September to about 3 million tons, according to industry group Aço Brasil.

The home market is clearly under strain. Domestic sales fell 6.5% in October to 1.81 million tons, hurt by softer orders from the automotive sector and construction.

Flat products, which go into cars and appliances, dropped 7.3%, while long products used in civil works fell 5.5%. From January to October, production reached 28 million tons, down 1.8% year-on-year, and internal sales edged 0.3% lower to 17.86 million tons.

To keep plants loaded, mills are relying more on exports. Overseas shipments jumped 28% in October to 907,000 tons, led by semi-finished products, which climbed 29% to 669,500 tons.

Despite new US tariffs on Brazilian steel and aluminium introduced earlier this year, total exports in 2025 are up 4.6% so far, reaching 8.74 million tons.

Brazil braces for steel tariff showdown

Imports tell a more complex story. Overall volumes dropped 21.4% in October compared with a year earlier, to 473,400 tons, trimming year-to-date growth to 6.1%.

Flat steel imports fell 4.3% and long products 12.2%, but special steel arrivals more than doubled, from 34,500 to 77,400 tons, reflecting demand from higher-value industries.

Distributors say they are slowing new purchases and accelerating customs clearance of cargo already in Brazilian ports as they brace for possible anti-dumping surcharges the federal government is expected to define between late November and early 2026.

Industry leaders argue that heavily discounted foreign steel, often from Asia, is eroding local margins and investment capacity. For international readers, the stakes go beyond mill profits: steel underpins housing, infrastructure, autos and energy projects.

The way Brasília calibrates tariffs and anti-dumping rules in the coming months will shape job creation, regional development and the cost base of major projects across Latin America’s largest economy.
