Latin America Steel Wrap: CSN ADR Surges 8.65%
Key Facts
- CSN ADR surged 8.65% to US$1.13, the strongest one-day gain among major Latin American steel names on Tuesday, September 1, 2026.
- Gerdau shares rose 1.74% to US$4.69, modestly outperforming the SLX steel-producers ETF, which added 0.30% to US$108.34.
- Ternium advanced 1.55% to US$55.67, reflecting Mexico’s tariff wall of up to 50% on non-FTA steel products and USMCA-linked auto demand.
- Chinese steel holds 45.4% share of Latin America’s steel imports, keeping regional import penetration near 39.7% of consumption in 2025 despite tariff walls.
- Brazil first-half import penetration hit 22.5% well above historical norms, while a 25% tariff on above-quota imports of 19 steel products runs through June 2027.
- Latin American apparent steel consumption was barely growing, up just 0.1% year on year to 6.5 million tonnes in March 2026, with Alacero projecting only 0.5% growth for the full year.
Today’s Focus
Latin American steel shares closed mostly higher on Tuesday, September 1, 2026, with CSN’s New York-traded ADR jumping 8.65% to US$1.13, the standout move among regional producers. Gerdau added 1.74% to US$4.69, while Ternium rose 1.55% to US$55.67. The global steel-producers ETF SLX finished up 0.30% at US$108.34.
The rally sits atop a defensive policy floor: Brazil maintains a 25% tariff on above-quota imports of 19 steel products through June 2027 and five-year anti-dumping duties on Chinese cold-rolled, coated and hot-dip galvanised flat steel. Mexico applies tariffs of up to 50% on 1,463 non-free-trade-agreement products, including steel, layered on a 25% levy in place since August 2023.
Yet the fundamental pressure has not disappeared. Chinese mills supplied 45.4% of Latin America’s steel imports in 2025, and regional import penetration approached 39.7% of consumption. Brazil’s first-half 2026 penetration of 22.5% remains far above historical norms.
Demand is tepid rather than collapsing. Latin American apparent rolled steel consumption rose just 0.1% year on year in March 2026, while automotive output grew 1.1% in the first four months. Ternium is guiding for Mexican steel demand growth of about 4% in 2026, anchored in nearshoring and infrastructure.
What matters today. CSN’s 8.65% surge shows investors rewarding tariff-shielded Brazilian mills even as Chinese import penetration keeps margins structurally compressed.
01 The session in one read
CSN’s American depositary receipt was the clear winner among Latin American steel shares on Tuesday, September 1, 2026, jumping 8.65% to US$1.13. The move marked the strongest one-day gain for any major regional producer in the session and came without a single company-specific announcement.
Gerdau closed at US$4.69, up 1.74%, and Ternium ended at US$55.67, up 1.55%. All three names outpaced the broader steel-producers ETF SLX, which added just 0.30% to US$108.34.
The equity moves on Tuesday, September 1, 2026 reflect a market that sees tariff protection as durable but not sufficient to restore pricing power. CSN’s outsized gain likely captures short-covering and relief that the Brazilian duty framework remains intact through mid-2027, while Gerdau and Ternium posted steadier, demand-linked advances. The variable to watch is whether Latin America’s quarterly import penetration stays near the 22.5% Brazilian reading or climbs back toward the 39.7% regional import penetration seen in 2025.
02 The board
The price board showed a clear Brazilian tilt. CSN’s +8.65% leap to US$1.13 dwarfed Gerdau’s +1.74% gain to US$4.69, suggesting investors treated the former as a higher-beta play on the country’s tariff-protected flat-steel complex.
Ternium’s +1.55% rise to US$55.67 kept the Mexican producer within striking distance of its recent range. The SLX ETF, a basket of global steel producers, settled at US$108.34, up 0.30 percent, confirming that Latin American names led rather than followed the global steel sector.

03 What moved it
The single largest driver remains policy: Brazil’s 25% tariff on above-quota imports of 19 steel products, renewed through June 2027, plus five-year anti-dumping duties on Chinese cold-rolled, coated and hot-dip galvanised flat steel. These measures shield the domestic price lists of Gerdau, CSN and Usiminas.
Mexico offers a parallel wall. Tariffs of up to 50% on 1,463 products from countries without a free-trade agreement, including steel, sit alongside a 25% levy on non-FTA steel in force since August 2023. Ternium, the main Mexican flat-steel producer, is the principal beneficiary.
Against that protection, the pressure from cheap Chinese tonnage is unrelenting. Chinese mills accounted for 45.4% of Latin America’s steel imports in 2025, helping push regional import penetration toward 39.7% of consumption, and Brazil’s own first-half 2026 penetration remains elevated at 22.5%.
04 The Latin American read
For a foreign investor, the region’s steel trade is a story of two layers. The first is a politically entrenched tariff regime that keeps domestic mills from being undercut on price, which is why CSN can rise 8.65% in a single session without a profit warning or an upgrade.
The second layer is volume. Latin American apparent rolled steel consumption grew only 0.1% year on year to 6.5 million tonnes in March 2026, and Alacero projects full-year apparent consumption growth of just 0.5% to 75.6 million tonnes. Construction is broadly flat, while automotive output rose 1.1% in the first four months of 2026.
05 The names to watch
CSN is the volatility leader: its ADR trades at a low absolute price, so small changes in import data or tariff rhetoric produce outsized percentage swings. The company is also the most exposed to flat-steel competition from Chinese cold-rolled and coated product.
Gerdau offers a steadier profile, with long-steel exposure tied directly to construction and infrastructure spending across Brazil and the Americas. Its 1.74% gain on Tuesday, September 1, 2026 suggests investors see demand holding rather than accelerating.
Ternium is the Mexican bellwether. Management guides for Mexican steel demand growth of about 4% in 2026, anchored in infrastructure projects, nearshoring-related factory construction and USMCA-linked auto orders, even as total consumption remains below 2023 levels.
06 The outlook
The path forward hinges on whether tariff walls can hold back Chinese tonnage while demand improves from its near-flat trajectory. Brazil’s 22.5% first-half import penetration is the clearest warning that protection has not solved the problem. If automotive output keeps rising at 1.1% and Ternium’s 4% Mexican growth forecast proves accurate, regional mills can defend margins; if Chinese imports climb further, the tariff-shielded rally in names like CSN will look fragile.
07 What to watch
- Brazil import penetration: Whether the 22.5% first-half 2026 reading falls toward historical norms or climbs back toward the 39.7% regional share.
- Chinese export pricing: Cheap Chinese cold-rolled and coated steel remains the central margin threat despite Brazil’s anti-dumping duties.
- Mexican nearshoring demand: Ternium’s 4% growth guidance depends on infrastructure and USMCA-linked auto orders materialising.
- Regional auto output: The 1.1% year-on-year rise in Latin American automotive production is the main demand floor for flat steel.

Brazil applies a 25% tariff on above-quota imports of 19 steel products through June 2027 plus five-year anti-dumping duties on Chinese cold-rolled, coated and galvanised flat steel.
Is Chinese steel still a threat?
Yes. Chinese mills supplied 45.4% of Latin America’s steel imports in 2025, and regional import penetration approached 39.7% of consumption.
