Key takeaways:
China-origin private capital is now moving into the gap. With flat steel routes into Brazil narrowing, Chinese-backed groups are planting mills in Paraguay focused on long steel — rebar and wire rod — a segment that remains largely open to imports and has yet to face equivalent trade remedy action, according to sources.
A Brazilian distributor source based in São Paulo told Fastmarkets that Chinese representatives linked to steel operations have recently conducted in-person visits to distribution companies in Brazil — including in São Paulo and Paraná — without prior scheduling, in what sources described as an effort to establish commercial channels for products sourced from Paraguay.
“Chinese representatives came directly to my office. No appointment was made. They simply arrived and knocked on the door,” the source said, adding that a market contact of theirs reported the same type of outreach in November 2025.
Paraná borders Paraguay, where one of those operations is taking shape. Aceros del Oriente S.A. — known as Acereste — is a Chinese-linked steel group establishing an integrated long-steel production base in Yguazú, a Paraguayan city in the Alto Paraná department.
According to a press release by IP Paraguay, a state-run news agency, the project is publicly supported by the country’s Ministry of Industry and Commerce as part of its industrialization and export-oriented manufacturing strategy, structured under the country’s maquila regime and backed by more than $30 million in reported investment.
The company’s business card lists its origin as Quzhou, Zhejiang, China, and additional units in Bolivia and three African countries: Nigeria, Mauritania and Senegal — though a trader source told Fastmarkets the operation is backed by a Fujian-based investor. The “Acereste” name does not appear consistently across regions, suggesting the company operates under different names depending on where it is established.
The visiting team arrived well-prepared, according to the Brazilian distributor source. “They are very reserved, but they did their homework properly. They know about the recent price increases,” the distributor source said.
Fastmarkets’ monthly price assessment for steel hot-rolled coil domestic weekly, exw Brazil was 4,110-4,200 Reais ($821.5-839.5) per tonne on Friday May 15, unchanged from May 8. The anti-dumping investigation into Chinese hot-rolled flat steel imports remains ongoing, and market participants expect it to result in a high tariff.
The corresponding weekly price assessment for steel cold-rolled coil, domestic weekly, exw Brazil was 4,750-5,100 Reais per tonne on Friday, widening downward by 50 Reais per tonne from 4,800-5,100 on May 8, but up by 1.59% from February 13 — the week when anti-dumping measures on Chinese CRC were implemented in Brazil.
Fastmarkets’ weekly price assessment for steel hot-dipped galvanized coil, domestic, weekly, exw Brazil was 4,970-5,250 Reais per tonne on Friday, steady from May 8, but up 0.62% from March 13 — the first assessment after anti-dumping measures on Chinese coated steel came into effect. At that point, this price was published monthly.
Fastmarkets’ weekly price assessment for steel reinforcing bar (rebar), domestic, weekly, exw Brazil was 3,500-3,800 Reais per tonne on Friday, flat from May 8 and up by 7.21% from April 10, the previous month.

The initial product focus of Acereste’s Yguazú plant is rebar, with some wire rod exposure in later phases, according to market discussions and early-stage project descriptions. The Brazilian distributor source said current activity is oriented toward bar products rather than coil or flat steel — an entry strategy targeting fragmented downstream markets rather than integrated heavy industrial supply contracts.
The plant is planned to produce 17,000 tonnes of steel products per month, with around 70% of output reportedly destined for Brazil — a volume and direction that leaves little ambiguity about the primary market the operation is designed to serve. A greenfield project is under development, with production expected to begin around June, according to sources.
A trader source who has worked with Chinese steel mills said the Yguazú plant’s estimated annual capacity of around 200,000 tonnes is too small to be meaningful in any serious steel market context. He suggested the investment may be driven less by steel production economics and more by opportunities arising from differences in trade regimes.
Brazil was China’s eighth-largest steel export destination in 2025, absorbing approximately 2.8% of China’s total steel export tonnage. Nevertheless, Brazil’s trade remedy proceedings against Chinese steel have intensified since 2024, when domestic mills filed for anti-dumping relief on cold-rolled coil, coated steel and pre-painted steel imports from China.
So far in 2026, measures have been approved for all of those investigations, with duties ranging from $284.98 to $709.63 per tonne. Meanwhile, long steel, including rebar and wire rod, has yet to face equivalent action, leaving it as the segment of least trade remedy exposure for Chinese-linked exporters into Brazil.
A separate investigation into Chinese and Russian wire rod is ongoing.
The remaining Brazilian anti-dumping investigations on steel are:
• Tinplate from Germany, Japan and the Netherlands;• Hot-rolled flat steel from China;• Steel wire rod from China and Russia;• Hot-rolled stainless flat steel from China, India and Indonesia;• Seamless tube from Ukraine (review), India, Malaysia and Thailand.
In addition to the new measures in force and the ongoing investigations, there are also anti-dumping duties imposed on tinplate from China, in place since October 17, 2024, as well as on heavy plate from China, South Africa, South Korea and Ukraine, and on cold-rolled stainless steel of grades 304, 304L, 304H (austenitic) and 430 (ferritic) from China and Taiwan.
By early 2026, with CRC and coated steel final measures in force and a preliminary affirmative determination on HRC already on the table, Chinese monthly shipments to Brazil had fallen to their lowest level in the data series — from peaks above 400,000 tonnes in 2024 to below 100,000 tonnes in March 2026.
“It’s just like all other anti-dumping cases we have seen. Inquiries just keep falling, and once the market shifts like this, there’s no going back,” a second China-based trading source said, referring to Brazilian rerollers’ demand throughout 2025.

As Chinese steel exports to Brazil compress under successive trade measures, the pressure is finding new outlets — and creating new legal and regulatory headaches for the region.
Flavia Loss, who holds a PhD in International Relations from the University of São Paulo, described the emerging pattern as trade triangulation: Chinese-linked production entering Brazil via third countries with preferential access, bypassing Mercosur’s common external tariff structure.
“This is a political economy problem for Brazil,” she said. “We need to maintain strong relations with China, our main trading partner, and with Paraguay, our Mercosur partner. At the same time, we have to manage the tensions this creates within the bloc.”
The legal ambiguity runs deeper than tariff arbitrage. Rules of origin and corporate structures complicate enforcement. “You can argue that production is taking place in Paraguay,” Loss said, “but in practice these are Chinese-owned companies.”
The Acereste case sits at the intersection of these tensions. A paper published by the Center for Analysis and Dissemination of the Paraguayan Economy noted that between 2024 and 2025, more Chinese companies have established themselves in Paraguay, encouraged by the government’s active foreign investment attraction policy.
Acereste is specifically named in the paper as a company promoted by the Paraguayan government under one of the country’s fiscal incentive regimes — explicitly for producing goods destined for the Brazilian market.
Yet the same paper noted that Paraguay’s manufacturing sector associations have pushed back, arguing that Paraguay would derive greater economic and technological benefit from maintaining its relationship with Taiwan than from deepening ties with China — a tension that runs through the broader regional dynamic Loss identified.
Paraguay’s formal recognition of Taiwan gave that debate an added edge. “Paraguay is navigating between maintaining its relationship with Taiwan and managing growing economic dependence on China,” Loss said. “If they [China] cannot enter one way, they will find another.”
