Secondary Zinc Oxide Production Fell in February, While Secondary Zinc Oxide Payables Remained Relatively Firm. What Trend Will Secondary Zinc Oxide Show in March?

This week, ferrous metals rebounded from the bottom. At the start of the week, coking coal and coke led the futures higher, mainly driven by rising crude oil prices in the overseas market, which pushed the energy and chemicals sector stronger accordingly; mid-week, both the U.S. and Iran signaled a more relaxed stance toward war, easing geopolitical tensions, while coal prices fell in tandem, weakening the cost-side logic, and ferrous metals fluctuated at highs; in the latter half of the week, worsening short-term liquidity issues in BHP's iron ore port inventory triggered stronger iron ore prices in the overseas market, while the Middle East situation remained volatile, reinforcing cost support and pushing ferrous metals higher again. In the spot market, supported by futures, end-user and arbitrage purchase sentiment both improved WoW this week......

SMM News, Mar 13: This week, the recycling volume of waste lead-acid battery recyclers rebounded significantly WoW, with the recycling volume of some recyclers rising 40% from the initial stage of work resumption. However, affected by downstream consumption not yet having fully recovered and a relatively low volume of retired scrap battery, some enterprises still saw recycling volume that had not returned to pre-holiday levels. As secondary lead smelters resumed work at a relatively slow pace and demand for scrap battery had not yet surged, SMM expected the purchase prices of waste lead-acid battery to stabilize next week. Domestic secondary crude lead smelters posted a poor operating rate, with some enterprises suspending production due to environmental protection-related controls. Suppliers held firm offers, and the current mainstream ex-factory prices excluding tax stood at 15,250-15,400 yuan/mt. If containing some antimony and tin metals, ex-factory offers were at least 15,500 yuan/mt. At present, imported lead supply was ample, and suppliers had relatively weak bargaining power, giving downstream enterprises near ports a greater advantage in purchases. SMM expected domestic secondary crude lead supply to remain tight in the short term, with imports serving as the main supplement. » Subscribe to View Historical SMM Metal Spot Prices

In contrast to the typical price declines seen during the traditional spring festival low season from January to February in previous years, China’s domestic manganese sulfate market has recently staged an independent rally of “strong performance amid the off-season”, with prices rising steadily along the way.

In the fields of precious and rare metals, compared with well-known categories such as gold, silver, and platinum-group metals, osmium has always remained a niche yet highly distinctive presence. With its unmatched physicochemical properties, it has become an indispensable key material in high-end industry and scientific research. Even though it receives limited market attention, it still possesses irreplaceable value. This article will provide a comprehensive breakdown of osmium metal, covering its basic properties, resource supply, application scenarios, and market characteristics, to offer a full understanding of this “king of density.” I. First Encounter with Osmium: A Hardcore Outlier Among the Platinum-Group Metals Osmium, with the chemical symbol Os and atomic number 76, belongs to the platinum-group metals. It is a Group VIII transition metal on the periodic table and also one of the rarest metals found in nature. As one of the six major members of the platinum-group metal family, osmium has no independent ore deposits and is commonly associated with platinum, iridium, ruthenium, rhodium, and palladium. It can only be recovered through purification during platinum ore smelting and cannot be extracted through standalone large-scale mining. This inherent characteristic directly defines its scarcity. Osmium’s physicochemical properties are truly unique in the world of metals, with highly recognizable core characteristics: first, it has the highest density in the world. Under standard conditions at 20°C, its density reaches 22.59 g/cm³, far exceeding that of gold (19.32 g/cm³) and platinum (21.45 g/cm³). It is currently the densest naturally occurring metal known, and at the same volume, it weighs far more than various conventional precious metals. Second, it demonstrates excellent high-temperature resistance, with a melting point of 3,033°C and a boiling point exceeding 5,000°C. It remains highly stable in high-temperature environments and can adapt to various industrial and scientific applications under extreme heat. Third, it has outstanding hardness and strong corrosion resistance. With a Mohs hardness of 7, it is hard, durable, and wear-resistant, and is difficult to corrode under conventional acidic or alkaline conditions. However, its drawbacks are also quite evident: it is highly brittle and has extremely poor plasticity, making it impossible to process through conventional mechanical methods, so it is mostly used in powder or alloy form. A key safety precaution must be emphasized here: when osmium metal is heated in air to above 100°C, it slowly oxidizes to form osmium tetroxide (OsO₄). This substance is highly irritating, highly volatile, and somewhat toxic. Therefore, the entire process involving osmium, including production smelting, storage and transportation, and deep processing, must be carried out under the protection of inert gas and in strict compliance with operational standards. These exceptionally high compliance and control requirements further raise the barriers to osmium’s production and application. II. Extreme Scarcity: Osmium’s Resource Endowment and Supply Landscape Osmium is far rarer than commonly recognized precious metals such as gold and platinum, and it can be regarded as a “niche treasure” in the precious metals sector. Relevant data show that the average abundance of osmium in the Earth’s crust is only about 0.001 ppm, making it one of the least abundant stable elements in the crust. Globally, identified recoverable reserves are extremely limited, and resource distribution is highly concentrated, without the formation of widely distributed ore deposits. Supply side, the scarcity of osmium is even more pronounced. As there are no standalone mines, global osmium production is entirely dependent on platinum ore mining and smelting, with capacity remaining at an extremely low level year-round. Global annual production is about 1 mt (data from the International Platinum Group Metals Association), while China’s annual production is less than 100 kg, with supply far below that of other platinum group metals. From the global supply landscape, traditional major platinum group metal-producing countries such as South Africa and Russia control the vast majority of the world’s osmium resources and smelting capacity. Industry supply shows a highly monopolized pattern, with extremely low supply elasticity. Minor changes in mining progress, geopolitical conditions, environmental protection-related controls policies, and platinum group metal smelting capacity all directly affect global osmium supply. This dual characteristic of “inherent resource scarcity + constrained supply” has kept the osmium market in a long-term tight supply-demand balance and has also given it strong price resilience and fluctuation elasticity, securing a unique position in the rare metals market. 3. Exclusive to High-End, Cutting-Edge Applications: Core Application Scenarios of Osmium Although osmium has limited production and a relatively narrow range of applications, its exceptional physical and chemical properties have enabled it to take root precisely in high-end niche fields, making it an irreplaceable core material in many advanced applications. Downstream demand is concentrated and highly rigid, with no low-cost substitutes currently available. Its core applications are mainly concentrated in four major fields: 1. Special Hard Alloys: Core Raw Material for High-End Wear-Resistant Components Osmium-based alloys made by melting osmium with metals such as iridium and platinum combine ultra-high hardness, wear resistance, and corrosion resistance, making them key core materials for high-end precision instruments. These alloys are widely used in high-precision bearings for high-end watches and precision instruments, premium fountain pen nibs, professional turntable styluses, medical precision scalpels, and high-end wear-resistant mechanical components. They can significantly improve component service life and durability, making them suitable for long-term, high-load, high-wear operating environments, and they are core wear-resistant materials in the high-end manufacturing sector. 2. Industrial Catalysis: Dedicated High-Efficiency Additive for Fine Chemicals Osmium and its compounds have excellent catalytic activity and serve as dedicated catalysts in certain fine chemical and organic synthesis reactions. Especially in special chemical processes such as hydrogenation and oxidation reactions, they offer high catalytic efficiency and strong reaction selectivity, effectively optimizing process flows and improving product purity and yield. Although the unit consumption of osmium catalysts is extremely low, they are rigid process necessities and are difficult to replace with other common metal catalysts, resulting in relatively strong downstream demand stability. 3. Scientific Research and Detection: Essential Specialty Consumable for Laboratories Although osmium tetroxide is toxic, it has irreplaceable value in scientific research. It is a high-quality staining agent for biological samples and microscopic material sections under electron microscopes, significantly enhancing the clarity and contrast of observed samples, and is an indispensable experimental reagent in frontier research fields such as materials science and life sciences. Meanwhile, high-purity osmium powder was also widely used in high-end scientific research experiments and the R&D of specialized new materials, serving as a niche but essential consumable for major research institutes and high-end laboratories. 4. High-End Specialized Fields: Core Components for Military and Aerospace Applications Leveraging its core advantages of high density, high-temperature resistance, and high stability, osmium was also applied in specialized high-temperature components for aerospace and military applications, precision guidance components, as well as niche scenarios such as high-end electrical contacts and wear-resistant coatings. These applications were all concentrated in cutting-edge, high-precision sectors. Although the volume of each individual application was small, the product value-added was extremely high. Moreover, with the technological iteration and development of high-end manufacturing and the military and aerospace industries, related demand had the potential for steady growth. IV. Summary of the Core Characteristics of the Osmium Metal Market Overall, as a rare category among platinum group metals, osmium had highly distinctive core characteristics: extreme scarcity on the resource side, highly monopolized supply with insufficient elasticity; application-side concentration in high-precision, cutting-edge fields, with rigid and irreplaceable demand; and unique physicochemical properties, combining both advantages and application barriers. Unlike the market-driven fluctuation logic of conventional bulk commodities, the osmium market was significantly affected by factors such as supply-side changes, downstream demand from high-end industries, and compliance costs. The overall market size was small, and trading frequency was relatively low, placing it in the category of niche rare precious metals. Its core value always revolved around the two key points of “scarcity” and “irreplaceability,” making it an indispensable key metal material in high-end industrial and scientific research fields.

This week (March 6–12), the operating rate of SMM copper wire and cable enterprises was 66.59, up 5.69 points MoM and down 10.62 points YoY. The operating rate steadily rebounded this week, mainly due to a slight correction in copper prices that drove order release, coupled with support from concentrated power grid deliveries, though the current pace of order recovery remained weaker than in the same period last year. By sector, orders from the power segment continued to support enterprise production schedules, orders from the new energy segment also improved, while construction project orders remained weak, dragging on overall operating rates. Inventory side, the correction in copper prices drove enterprises to restock for rigid demand, but as enterprises maintained production schedules, days of raw material inventories fell 0.31 days MoM this week; for finished product inventories, the correction in copper prices boosted downstream consumption, but high copper prices still restrained end-user purchase willingness, so days of finished product inventories fell 0.41 days MoM. Looking ahead to next week, current orders on hand from the power and new energy sectors will continue to provide the main support for production scheduling. SMM expects the operating rate of copper wire and cable next week (March 13–19) to increase 3.45 points MoM to 70.04, down 4.49 points YoY.

Philippines Market: Tight Supply and Surging Freight Rates Supported Ore Prices to Fluctuate at Highs Philippine nickel ore prices rose sharply this week. In terms of prices, Philippine nickel ore CIF China quotes were $64-68/wmt for Ni 1.3% grade, $71-75/wmt for Ni 1.4% grade, and $78-82/wmt for Ni 1.5% grade, up $6 WoW. The average CIF price from the Philippines to Indonesia was $65.5/wmt for 1.3% grade and $72.5/wmt for 1.4% grade. Supply side, although the Philippines was transitioning into the dry season, mining hubs such as Surigao and Homonhon continued to see heavy rainfall due to a low-pressure area (LPA) east of Mindanao. Although Metro Manila and most parts of Luzon saw hot and sunny weather, the probability of rainfall exceeding 50 mm in Surigao and Caraga remained “very high.” Strong thunderstorms and scattered precipitation were expected to further intensify during March 9 to 13. Affected by the trough of the low-pressure area and the easterlies, persistent rainfall may continue to disrupt open-pit mining and vessel loading operations in southern regions. Market supply remained scarce. Driven by both supply tightness caused by cuts in Indonesia’s RKAB quotas and expected supply gaps, mainstream prices for Philippine nickel ore have surged recently. As of Friday, March 13, nickel ore inventory at Chinese ports stood at 5.23 million mt, down 500,000 mt WoW. Current total port inventory was equivalent to about 41,100 mt Ni in metal content. Demand side, China’s NPI prices rose this week, with spot transaction prices up about 1,089.9 yuan per nickel unit. As smelters had sufficient stockpiling earlier and showed limited acceptance of recently high-priced nickel ore, most were currently taking a wait-and-see stance. In terms of ocean freight rates, affected by a sharp jump in oil prices, nickel ore freight rates climbed, with the ocean freight rate from the Philippines to Lianyungang reaching $15/mt or above. Looking ahead, Philippine nickel ore prices are expected to continue fluctuating at highs. Indonesia Market: Under Weather Disruptions and RKAB Policy Clarification, Tight Supply Continued Indonesia's local nickel ore prices rose somewhat this week. Indonesia’s nickel ore benchmark price (HPM) for the first half of March was set at $17,104/dmt, down 3.21% MoM. According to SMM Indonesia nickel ore premium data, average premiums for 1.4%, 1.5%, and 1.6% grade laterite nickel ore were reported at $35, $39, and $39.5/wmt, respectively. Among them, the port arrivals under domestic trade price for 1.6% grade was $65.2-74.2/wmt. The simultaneous strengthening in premiums this month reflected both the release of smelters’ restocking demand and pessimistic expectations over RKAB quota cuts, while the delivered price of 1.2% grade limonite ore also edged up to $24-26/wmt. From the supply and demand fundamentals, as of March 13, Indonesia’s key nickel ore producing areas of Morowali, Konawe, and Halmahera were affected this week by strong thunderstorms and extremely high humidity of up to 94%. Weather continued to fluctuate, causing soil to become highly saturated and seriously hindering mine drying and transport operations. Morowali and Konawe will face a heavy rainfall system over the weekend with precipitation probability as high as 80%, while Halmahera, under high-humidity conditions, is expected to see rainfall intensity rebound again next Friday, with overall logistics capacity remaining constrained. At present, RKAB approvals for most small- and medium-sized mines remained pending. As existing quotas could no longer be used for next month’s production and sales, rising supply uncertainty was pushing nickel ore prices higher. Demand side, as some Indonesian smelters faced uncertainty over nickel ore resources and found it difficult to secure high-grade saprolite ore, nickel ore prices remained firm. To secure raw material supply, some smelters even raised trading bonuses. Overall, although the impact of the current MOMS system failure on mines had largely faded, overall nickel ore supply remained tight. Although spot supply of limonite ore was relatively sufficient, some related production lines were currently running at low load due to a tailings dam landslide accident at some MHP projects in an Indonesian industrial park, leading to temporary weakness in overall demand. However, considering concerns among some Indonesian smelters over RKAB approval uncertainty, raw material stockpiling demand from newly commissioned projects, and continued growth in demand from outer islands, limonite ore prices are expected to closely track saprolite ore and remain high. On the policy side, in response to recent market rumors that “production quotas (RKAB) will be uniformly supplemented by an additional 25%-30%,” Tri Winarno, Director General of Minerals and Coal at Indonesia’s Ministry of Energy and Mineral Resources (ESDM), clarified on March 3, 2026, that RKAB supplements would be based on individual assessments of enterprise production capacity and compliance, rather than a uniform proportional increase, and indicated that the approval process would start in H2 2026. Officials emphasized that this was a routine regulatory process for resource optimization, rather than a passive countermeasure to the previous output cap policy. Looking ahead, affected by the relatively slow progress of RKAB approvals, nickel ore prices are expected to remain more likely to rise than fall in April.
