Brazil's development ministry alleged it has found evidence in a recent investigation of China and India exporting pre-painted flat steel at too far below market prices.
Brazil will not apply any duties as of now and will continue the scrutiny for the next 18 months, it said.
The investigation started in June 2024 after a request from Brazilian steelmaker CSN. This marks the third decision in all anti-dumping investigations in which the ministry has confirmed dumping without imposing provisional penalties.
Brazil has also identified steel dumping practices by China regarding both coated steel and cold-rolled steel.
Brazil's steel imports rose by nearly 30pc to 1.7mn metric tonnes in the first quarter from a year before. March imports increased by 21pc from the same month last year, despite a 25pc tariff in effect since June 2024 on 11 steel products from China.
Chinese sellers were responsible for 78pc of all flat steel imports into Brazil in the first quarter, according to Comex Stat, Brazil's foreign trade platform.
Brazilian steelmakers have been calling for more pragmatic trade defense measures to ensure fair competition.
