A Chinese-backed steel mill under construction on Peru's desert coast is drawing intense scrutiny from domestic producers, regulators and market participants, as its development trajectory intersects with a landmark anti-dumping ruling and unresolved questions about regulatory compliance. The project, described by market sources as part of a broader and deliberate rerouting of Chinese steel capital through Latin America's regulatory seams, has brought the region to the forefront of a global debate about trade remedy circumvention and the new geography of steel investment. The company behind the project is Acero Lima Shenglong, incorporated in Peru in July 2024 by three Chinese nationals.
Construction is underway on a 14-hectare site in Chilca, south of Lima. According to market sources cited by Fastmarkets, the mill is focused on long steel products, with rebar as the initial product and wire rod planned for a second phase, targeting an annual capacity of approximately 700,000 tonnes. The investment model follows a two-stage structure increasingly associated with Chinese overseas steel ventures.
In the first phase, the plant will import semi-finished billet from China and roll it into rebar for local and regional sales. In the second phase, the company intends to install electric-arc furnace (EAF) capacity, deepening vertical integration and strengthening the claim to Peruvian origin under trade remedy frameworks. Production is expected to begin in early 2027, according to sources familiar with the project timeline, though that schedule now depends on how regulatory uncertainties resolve.
A second trader source cited by Fastmarkets pointed to Fujian-linked investor capital behind the project, suggesting connections to a broader network of Chinese private investors. Fastmarkets was unable to independently confirm the ultimate ownership chain. The regulatory backdrop has become increasingly complicated.
Local media reports, citing information from Peru's Ministry of Production and the national environmental certification agency Senace, indicated that Acero Lima Shenglong had not submitted an Environmental Impact Assessment (EIA) — a mandatory step before construction can legally begin on industrial projects of this scale. Municipal construction licenses and urban development permits were also reported to be absent at the time of the first media coverage in March 2026. Peru's environmental enforcement agency OEFA inspected the site in December 2025 but concluded no sanctions were warranted because the plant was not yet operational, a finding that drew sharp criticism from domestic producers.
Acero Lima Shenglong issued a statement saying regulatory investigations had not found any infringements or violations on its part and that it was cooperating with the relevant authorities. Siderperu, the Gerdau-owned Peruvian steelmaker, publicly rejected the project. A company spokesperson told Fastmarkets: "Our concern is not the entry of new players, but that all compete under the same rules, standards and regulatory requirements.
Complying with the law is not optional." The steelmaker added that the sector faces growing distortions linked to subsidized imports, particularly from Asia, pressuring prices, margins and domestic production. On April 12, 2026, Peru's INDECOPI, the national competition and intellectual property authority, published Resolution 065-2026/CDB-INDECOPI in the official gazette El Peruano, issuing a final anti-dumping determination on wire rod originating in China. The ruling imposes duties of $81.30 per tonne for a period of five years, effective from the day after publication.
Named producers subject to the measure include Angang Steel Co, Angang Group Hong Kong Co, Benxi North Steel Rolling Co and Benxi Iron & Steel Hong Kong, among others. The measure covers tariff codes 7213.20.00.00, 7213.91.10.00, 7213.91.90.00 and 7213.99.00.00. Wire rod is precisely the product targeted for Shenglong's second-phase production at Chilca, meaning the ruling closes the direct export route for the same product the mill intends to manufacture.
Market sources told Fastmarkets the timing is not coincidental. Chinese wire rod exports to Peru spiked to approximately 38,300 tonnes in April 2026, among the highest readings in the series according to data from China's General Administration of Customs, consistent with a pre-tariff loading surge as exporters and buyers rushed shipments before the duty took effect. Fastmarkets' weekly price assessment for steel wire rod (mesh quality) export, fob China main port, was at $490-500 per tonne on July 28, unchanged from the previous week but down by $25-30 per tonne from the year-to-date high of $520-525 per tonne recorded on May 12.
Fastmarkets' monthly price assessment for steel wire rod (mesh quality) export, fob Latin America main port, was at $570-610 per tonne on July 3, remaining unchanged from the previous month. Peru's steel market remains structurally dependent on imported steel, with domestic production unable to meet local demand. The Association of Exporters (ADEX) reported that steel bar imports rose by 121.4% in January 2026 from a year earlier, underscoring rising import penetration.
Across Latin America, apparent consumption of rolled steel products rose by 1.3% year on year in 2025 to 74.1 million tonnes, according to Alacero, the Latin American Steel Association, even as regional production fell for a fourth consecutive year. Peru's manufacturing sector grew by 2.7% in 2025, with fabricated metal products expanding by 3.8%, according to the Sociedad Nacional de Industrias (SNI). Market participants are raising pointed questions about how these investments fit into regional steel supply chains.
"Both mills are very small by any serious steel industry measure," a third trader source based in China told Fastmarkets. "The capacity figures don't make sense as standalone industrial projects, but they do make sense as minimum viable origin-qualifying operations." Peru's bilateral free trade agreement with China — the first such agreement China signed with any Latin American country, in force since 2010 — adds a further dimension, providing investment protection provisions that Chinese-linked producers can invoke while also enabling the development of supply chains that may involve alternative origin structures, according to market participants. A separate investigation into wire rod from China and Russia is simultaneously underway in Brazil, a market that sources say could be one of the potential end destinations for output from Acero Lima Shenglong and Acereste, a comparable Chinese-linked long steel operation in Paraguay that Fastmarkets reported on in May.
Both projects are widely understood in the market to be linked to Fujian-based Chinese private capital, with sources describing this investor profile as trading- and investment-oriented rather than rooted in large-scale integrated manufacturing. Sebastián Sarapura Rivas, a historian at the Federal University for Latin American Integration, told Fastmarkets that the novelty of the Chilca project lies in the fact that, for the first time on a large scale, Chinese capital would be producing a manufactured product within Peru, directly competing with local producers. He noted that China's steel sector is simultaneously grappling with excess capacity and weakening domestic demand, particularly following the slowdown in its real estate market, making local production inside destination markets an increasingly plausible strategy for preserving market access amid growing trade barriers.
In April 2026, the Peruvian government approved the regulatory framework for privately managed special economic zones (ZEEP), introducing tax and customs incentives for designated industrial areas. Market participants said such incentives could help explain the growing interest from Chinese investors in projects tied to logistics and industrial hubs connected to the Port of Chancay. Production at Chilca remains targeted for early 2027.
Whether it gets there on schedule depends on three unresolved questions, according to Fastmarkets: whether Senace requires the missing environmental assessment before work continues, whether INDECOPI extends its scrutiny from wire rod imports to the mill producing them, and whether Brazil's own trade case narrows the market the project appears designed to reach. Acero Lima Shenglong was contacted by Fastmarkets for comment but had not responded by the time of publication.
