Amid Supply-Demand Tug-of-War, Magnesium Market Moves Sideways with Magnesium Prices and Industry Chain Products Showing Fluctuating Rangebound Trend [SMM Magnesium Weekly Review]

Publicado: Sep 18, 2025 15:56
[SMM Magnesium Weekly: Magnesium Market in a Tug-of-War Between Supply and Demand, with Prices and Industry Chain Products Exhibiting a Fluctuating Trend] This week, the performance of products related to the magnesium industry chain was influenced by both supply and demand, showing different trends. For dolomite, although leading mines resumed production, previous maintenance kept inventory at low levels. Meanwhile, the increase in operating rates of magnesium plants in major production areas drove up consumption, leading to a slight price increase supported by demand. In the magnesium ingot market, the tug-of-war between sellers and buyers intensified. In major production areas, demand was sluggish due to the post-delivery impact of last week's foreign trade orders. However, rising prices of raw materials such as dolomite bolstered magnesium plants' reluctance to sell, keeping prices firm in the short term due to cost support. In the long run, prices may trend downward due to strong supply and weak demand. At the Tianjin Port FOB market, the wait-and-see sentiment was strong. Early spot orders saw active transactions, but the quotation range expanded later. With the National Day holiday approaching and the US dollar weakening, traders adopted a cautious stance toward October shipments, and price trends will need to be verified after the holiday based on shipment conditions. In the magnesium powder market, supply-side production increased slightly, with manufacturers mostly fulfilling previous orders. After a brief pre-holiday stockpiling demand emerged, downstream and overseas buyers turned to a wait-and-see approach due to rising prices, resulting in mediocre transactions. Prices edged up slightly with cost support but remained rangebound and stagnant. Magnesium alloy prices fluctuated in line with magnesium ingots. On the supply side, manufacturers scheduled production based on orders, with spot supply tight and some orders scheduled for next month. Operating rates increased with order volumes. On the demand side, sectors such as NEVs saw rising demand, but downstream die-casting plants exhibited fear of high prices, and transactions at high prices remained to be followed up.

1 Market Review

1 Dolomite

This week, the ex-factory tax-exclusive price of 1-3 cm dolomite (Wutai) was 108 yuan/mt, up 30 yuan/mt WoW, and that of 2-4 cm dolomite (Wutai) was 138 yuan/mt, up 10 yuan/mt WoW.

Dolomite prices edged up this week. Recently, leading dolomite mines resumed production and operations. Considering that earlier maintenance and production halts had reduced inventories of leading dolomite producers to low levels, coupled with rising operating rates of magnesium plants in major production areas and increased dolomite consumption, dolomite prices edged up with demand support.

1.2 Magnesium Ingot

1.2.1 Magnesium Ingot (Fugu, Shenmu—Major Production Areas)

This week, mainstream quotations for 99.90% magnesium ingot in major production areas were 16,700–16,800 yuan/mt, with magnesium prices fluctuating rangebound.

Magnesium prices fluctuated rangebound this week. At the beginning of the week, the quotation range of magnesium plants in major production areas widened. Leading magnesium plants held strong reluctance to sell, with firm market quotations at 17,000 yuan/mt. Some smaller plants sold at market prices, pushing transaction prices down to 16,800 yuan/mt. However, influenced by mid-week news, some traders entered the market for procurement, leading to a slight recovery in magnesium market transactions, and prices rebounded to 17,000 yuan/mt. Overall, downstream sentiment remained bearish, with market transactions dominated by just-in-time procurement. Production resumptions at magnesium plants increased supply pressure, keeping short-term magnesium prices under pressure. This week, magnesium prices showed a rangebound trend, with an intensified tug-of-war between sellers and buyers in the magnesium market. Following the concentrated delivery of foreign trade orders last Saturday, magnesium prices bottomed out with demand support. However, this week's demand was thus depleted, and market transactions lacked follow-through momentum, leaving insufficient upward momentum for magnesium prices. Low-priced sources subsequently emerged. By mid-week, magnesium plants grew more reluctant to sell due to rising raw material prices such as dolomite, ferrosilicon, and coal, leading to another uptick in quotations. Overall, the supply-demand pattern of strong supply and weak demand in the magnesium market is difficult to reverse in the short term. Magnesium prices remain firm in the short term with cost support but are expected to trend downward in the long run.

1.2.2 Magnesium Ingot (Tianjin Port—FOB China)

This week, the FOB China price was quoted at $2,380–2,420/mt, averaging $2,400/mt. FOB transaction prices varied significantly this week, with traders mostly maintaining high quotations.

The export market was generally characterized by wait-and-see sentiment this week. Traders were mostly cautious about orders for October-December shipping dates, mainly making inquiries. Supported by rising raw material prices such as dolomite and coal, magnesium prices stabilized with an upward trend after hitting bottom last Friday, with most factory quotations firm or slightly raised. From last Friday to Tuesday this week, overseas markets saw active transactions, with a daily average trading volume of 500-600 mt and shipping schedules primarily focused on the spot market. The transaction price was approximately $2,350/mt. Starting from Wednesday, new order quotations were mostly concentrated in the range of $2,400-$2,490/mt, widening the market quotation range. As the National Day holiday approaches, traders remain uncertain about shipping schedules for October. It is expected that the market will continue its current trend next week. Whether FOB prices will pull back will depend on the actual shipment situation after the National Day holiday, and the continuous decline in the US dollar exchange rate has also made exporters more cautious in their quotations.

1.3 Magnesium Powder

This week, the mainstream tax-inclusive ex-factory prices for Chinese magnesium powder with a mesh size of 20-80 ranged from 17,900 to 18,100 yuan/mt; the Chinese FOB price ranged from $2,540 to $2,580/mt.

This week, magnesium powder market prices rose slightly under the support of raw material costs, showing an overall stalemate. Market transactions performed mediocrely, with magnesium powder plants mainly executing previous orders. Although production increased slightly, demand remained mediocre. At the beginning of the week, there was still some demand for stockpiling before the National Day holiday, but after prices strengthened, downstream players mostly adopted a wait-and-see approach, and purchase willingness slowed down. New order transactions in overseas markets were limited this week, with overall activity remaining low. It is expected that the short-term magnesium powder market will continue to fluctuate rangebound.

1.4 Magnesium Alloy

This week, the mainstream tax-inclusive ex-factory prices for Chinese magnesium alloy ranged from 18,400 to 18,550 yuan/mt, while the mainstream FOB prices for Chinese magnesium alloy ranged from $2,590 to $2,630/mt.

This week, magnesium alloy prices fluctuated in sync with magnesium ingot prices. On the supply side, most magnesium alloy manufacturers are scheduling production, and the magnesium alloy market is experiencing tight spot supply. Some traders report that it is difficult to find manufacturers that can meet the three-day cargo pick-up requirement. Currently, some magnesium alloy enterprises are scheduling shipments. According to SMM, some magnesium alloy enterprises have orders scheduled until early next month. As a result, the operating rates of some magnesium alloy enterprises have increased. On the demand side, there is an upward trend in demand from new application areas such as NEVs and EVs, leading to an upward trend in magnesium alloy demand. Overall, some magnesium alloy enterprises have raised their alloy processing fee quotations, but currently, downstream die-casting plants have a strong fear of high prices, and high-priced transactions are awaiting follow-up.

2 Weekly Summary

This week, the performance of products related to the magnesium industry chain showed different trends due to the combined influence of supply and demand. For dolomite, although leading mines have resumed production, earlier maintenance led to low inventory levels. The increase in operating rates at magnesium plants in the main producing areas has driven up consumption, leading to a slight price increase under demand support. The tug-of-war between sellers and buyers in the magnesium ingot market has intensified. The main producing areas are experiencing weak transactions due to demand depletion following the fulfillment of last week's foreign trade orders. However, the price increase of raw materials such as dolomite has boosted magnesium plants' reluctance to sell, keeping prices firm in the short term under cost support. In the long term, prices may trend downward due to strong supply and weak demand. The Tianjin Port offshore market has a strong wait-and-see atmosphere. Early spot orders saw active transactions, but later quotation ranges widened. Affected by the approaching National Day holiday and the decline in the US dollar, traders are cautious about shipping schedules for October, and price trends need to be verified by post-holiday shipment situations. In the magnesium powder market, supply-side production increased slightly, with producers mostly fulfilling previous orders. On the demand side, pre-holiday stockpiling needs briefly emerged but then shifted to a wait-and-see stance both downstream and overseas due to rising prices, resulting in mediocre transactions. Prices edged up with cost support and remained range-bound with little movement. Magnesium alloy prices fluctuated in line with magnesium ingots. On the supply side, producers scheduled orders for production, with tight spot supply and some orders scheduled until next month. Operating rates were adjusted upward in response to order volumes. On the demand side, demand from sectors such as NEVs rose, but downstream die-casting plants exhibited fear of high prices, and transactions at high prices remained to be followed up.

Mercado de magnésio interrompe tendência de queda com alta nos preços do carvão; produtores enfrentam custos crescentes
No início de agosto, o mercado de magnésio parecia preso em um impasse prolongado. Os ventos favoráveis do corte de produção de julho se dissiparam, e a oferta de magnésio primário se recuperou de forma constante. Enquanto isso, coincidindo com a calmaria do verão no exterior e a entressafra da fundição sob pressão no mercado doméstico, os pedidos de downstream eram escassos e o sentimento de compra atingiu o fundo do poço.

[SMM Análise do Mercado de Magnésio: Alta do Preço do Carvão Acende o Mercado de Magnésio, Consolidação de Dois Meses Finalmente Rompe, Cortes de Produção e Redução de Estoques Preparam o Terreno para a Próxima Alta] Ao entrar em agosto, o mercado de magnésio parecia ter caído em um impasse prolongado. O impulso dos cortes de produção de julho se dissipou, a oferta de magnésio primário se recuperou de forma constante, enquanto as férias de verão fora da China, combinadas com a baixa temporada da fundição sob pressão doméstica, deixaram os pedidos a jusante escassos e o sentimento de compra em ponto de congelamento. Com oferta e demanda fracas, os preços do magnésio ficaram firmemente travados em uma faixa estreita de 15.800–15.950 yuans/tonelada, com pouco espaço para se mover em qualquer direção. Em meados e no final de agosto, os preços chegaram a cair para 15.750 yuans/tonelada em determinado momento, com o mercado adotando amplamente uma postura de espera. Quando essa consolidação no nível mais baixo, que já durava dois meses, teria um ponto de virada permanecia desconhecido.

[SMM Análise Semanal do Magnésio: Pressão de Custos Impulsiona Alta do Magnésio, Demanda Fraca Limita Ganhos] Nesta semana, as cotações principais do lingote de magnésio 99,90% nas principais regiões produtoras ficaram em 16.050-16.150 yuans/t, alta de 300 yuans/t na comparação semanal, com preços FOB de US$ 2.280-2.380/t e média de US$ 2.330/t. Os preços do lingote de magnésio dispararam durante a semana, impulsionados pelo aumento dos custos de carvão e ferrossilício, somado a alguma reposição a preços mais altos no comércio exterior. No entanto, o mercado em geral permaneceu caracterizado por oferta forte e demanda fraca, com transações lentas a preços elevados e sinais de recuo surgindo na segunda metade da semana. A demanda externa não mostrou recuperação substancial, com a atividade de mercado dominada por consultas exploratórias, volumes limitados de pedidos reais e evidente pressão dos compradores por preços mais baixos, mantendo as negociações lentas. Os preços de pó de magnésio e ligas de magnésio a jusante acompanharam o aumento impulsionado pelos custos do lingote de magnésio, mas a demanda final por pó de magnésio permaneceu fraca, com algumas empresas reduzindo a produção ou suspendendo operações, exportações restritas e níveis de estoque em alta. O estoque à vista de ligas de magnésio estava amplo, a concorrência entre pares era intensa e as empresas de fundição sob pressão enfrentavam pedidos insuficientes e taxas de operação em declínio, mantendo as taxas de processamento sob pressão. No curto prazo, o suporte de custos e a demanda fraca estão em um cabo de guerra, e o impulso de alta nos preços do magnésio está perdendo força, com o mercado provavelmente retornando à consolidação. Daqui em diante, deve-se prestar muita atenção à liberação de pedidos domésticos e externos.
