[SMM Survey: Brazil Reviews Anti-Dumping Duties on Chinese Magnesium Ingots, Canada Plans Low-Carbon Magnesium Smelting] Brazil initiated the third review of anti-dumping measures on Chinese magnesium ingots on November 13, with a ruling expected within three months. This move is likely to affect the competitiveness of Chinese products in the Brazilian market. Meanwhile, an Indigenous community in Manitoba, Canada, has fully acquired the Minago project and plans to build a low-carbon magnesium smelter using innovative silicothermic reduction technology, which is expected to commence operation in 2027. This technology is 40% more energy-efficient than traditional methods and relies on green energy to achieve near-zero carbon emissions. It has the potential to challenge China's coal-based dominance in the industry and provide a new pathway for the global magnesium industry's low-carbon transition.

Brazil Initiates Review of Anti-Dumping Measures on Chinese Magnesium Ingots, Conclusion Expected Within Three Months

Brazil's Ministry of Development, Industry, Foreign Trade and Services announced on November 13, 2025, that, in response to an application from the domestic enterprise RIMA Industrial S.A., it has formally initiated a review procedure for the anti-dumping measures on magnesium ingots originating from China. The review analysis period spans from March 2021 to October 2025, with a conclusion expected within three months. Brazil has imposed an anti-dumping duty of $1.18 per kg on Chinese magnesium ingots since 2004, and this rate was maintained following the third sunset review in 2021. The outcome of this review will directly impact the competitiveness of Chinese magnesium ingots in the Brazilian market, highlighting the persistent trade barriers and supply chain dynamics in the global magnesium trade. It also provides an external market context for Europe's strategy to promote local green magnesium production.

Canada Leads Dolomite-Based Magnesium Smelting Project, Low-Carbon Process Aims for 2027 Startup

Following the full acquisition of the Minago project by the Norway House Cree Nation in Manitoba, Canada, a dolomite-hosted magnesium ore body with a thickness of up to 60 meters has been confirmed. The project plans to utilize an innovative silicothermic reduction process for green smelting. This technology extracts high-purity magnesium directly from dolomite through a vacuum metallurgy system, is expected to achieve 40% energy savings compared to traditional processes, and, by leveraging a green energy system, aims for near-zero carbon emissions. It has the potential to challenge the industry landscape long dominated by China's coal-based magnesium smelting technology. The project has already received C$1.25 million in initial government funding and is scheduled for commissioning in 2027, aiming to establish a significant low-carbon magnesium production site in North America. This mining project, fully owned by the Indigenous community, not only demonstrates the environmental potential of dolomite-based magnesium smelting but also provides a new technological pathway for the low-carbon transition of the global magnesium industry.

Magnesium Market Holds Up Well as Cost Support and the Tug-of-War Between Sellers and Buyers Continues [SMM Magnesium Weekly Review]

[SMM Magnesium Weekly Review: Magnesium Market Held Up Well, With Cost Support and a Tug-of-War Between Sellers and Buyers Continuing] This week, the overall magnesium industry chain held up well, with prices of all products generally raised. The raw material dolomite market remained stable, with ample supply and steady demand. Magnesium ingot prices consolidated at highs. At the beginning of the week, supported by rising energy costs such as ferrosilicon and coke and tight spot availability, prices jumped by 300 yuan/mt. Subsequently, downstream fear of high prices emerged, transactions failed to keep pace, and prices consolidated at highs. In foreign trade, the center of magnesium ingot FOB quotes moved up to $2,440-2,470/mt. Wait-and-see sentiment outside China remained strong, but influenced by bullish expectations in China, forward orders were gradually locked in. Magnesium powder prices remained firm, with strong cost support. Export data increased YoY, while domestic trade was mainly driven by just-in-time procurement. The benchmark price of magnesium alloy held up well, but the release of new capacity led to increased supply, processing fees stayed in the doldrums, and the market showed a pattern of strong supply and weak demand. Overall, cost support remained the core driver behind magnesium prices fluctuating at highs, while downstream acceptance of high prices was limited, and the market may continue this tug-of-war in the short term.

[SMM Analysis] China's Magnesium Exports Surge in Jan-Feb 2026, Geopolitical Turmoil Threatens Q2 Outlook

Jan-Feb 2026 China magnesium exports reached 72.7kt, up 3.4kt YoY. Magnesium alloy led with +33.1% YoY, orders booked through April. Magnesium ingot fell 6.8% due to weak European demand, while powder grew 10.3%. However, US-Israel conflict disrupted Middle East aluminum plants, halting regional magnesium orders and pressuring Q2 outlook despite the strong start.
