Latin American steel stalls at 6.5m tonnes as tariffs bite
Apparent steel demand in Latin America was virtually flat in March as rising tariffs on Chinese imports began to reshape the competitive landscape for regional producers.
Apparent rolled steel consumption in Latin America rose just 0.1% year on year to 6.5 million tonnes in March 2026, according to Alacero data. Crude steel output edged up 1.1% to 4.9 million tonnes for the month, though first-quarter production remained 1.9% lower at 13.9 million tonnes. Rolled output and exports also declined over the quarter.
The primary catalyst for the market is trade policy rather than organic demand growth. After a record flood of cheap Chinese steel pushed imports to roughly 40.3% of regional consumption in late 2025, governments responded. Imports fell 8.6% in March to 2.5 million tonnes and dropped 1.2% in the first quarter to 7.6 million tonnes.
Brazil has been the most aggressive, imposing five-year anti-dumping duties on Chinese cold-rolled steel starting around $323 per tonne, and on hot-dip galvanised coil between $285 and $710 per tonne. These measures followed a formal complaint by Usiminas regarding unfair pricing that damaged local mills. Mexico has matched this posture with duties of roughly $0.22 to $0.23 per kilogram on Chinese hot-rolled steel.
For major listed producers like Gerdau, CSN, Usiminas and Ternium, the dynamic marks a transition from defending market share to reclaiming pricing power. Equity markets have reacted cautiously, with the SLX steel-producers ETF and individual Latin American names showing only modest moves. The investment thesis remains defensive and policy-driven, hinging on whether tariffs will shift the profit pool toward domestic champions.
End-market conditions currently provide a fragile floor for revenues. Latin American automotive output increased 1.1% in the first four months of the year, while construction activity remained broadly flat versus a year earlier. Mexico’s planned tariffs of up to 50% on Asia-origin vehicles and 10-50% on auto parts could further shield the regional automotive supply chain.
The immediate risk for investors lies in the persistent trade deficit. Latin America still imported 1.9 million tonnes more steel than it exported in March, leaving a quarterly deficit of 5.9 million tonnes. Alacero forecasts full-year apparent consumption will grow a modest 0.5% to 75.6 million tonnes in 2026, before accelerating to 2.5% growth in 2027.
The key metric to track is the import share of consumption. Any sustained decline from the 40.3% peak reached in late 2025 will confirm that tariffs are successfully rebalancing the market and driving margin expansion for regional mills.
