Antimony Oxide Price Trend and Forecast 2026-2027

Key Takeaways

• Global antimony trioxide prices surged dramatically in 2025, rising from USD 20.09/KG in Q1 to a Q3 peak of USD 34.15/KG, a 70% increase in just two quarters. Q4 and Q1 2026 showed partial correction to USD 28.21/KG but prices remained well above pre-disruption baselines.
• The 2025 surge was driven entirely by the upstream antimony metal market disruption following China's September 2024 export licensing requirements and December 2024 ban on exports to the United States. Antimony oxide, produced by burning antimony metal with air, inherits metal market dynamics directly.
• South America (primarily Bolivia) emerged as a notable supply source, with Q3 2025 prices spiking to USD 44.70/KG before correcting. Bolivia's state-owned COMIBOL and private operators expanded output to serve Western buyers seeking non-Chinese supply.
• Europe tracked the global trajectory closely, moving from USD 19.36/KG in Q1 2025 to USD 34.90/KG in Q3, then stabilising near USD 31.81/KG in Q1 2026. Clariant, Campine, and specialty producers served flame retardant and solar glass markets.
• North East Asia held the lowest regional pricing throughout 2025, reflecting Chinese domestic inventory buildup as export channels narrowed. Q1 2025 opened at USD 17.15/KG, peaked at USD 23.68/KG in Q2, and settled near USD 20.65/KG in Q1 2026.
• The antimony oxide market forecast for 2026 points to continued elevated pricing, with further volatility driven by any additional Chinese export policy shifts, solar glass demand from expanding global PV installations, and defence-related flame retardant requirements.

What Is Antimony Oxide and Why Does It Matter?

Antimony trioxide (Sb₂O₃), commonly called antimony oxide, is a white crystalline powder produced primarily by oxidising antimony metal in air at controlled temperatures. It is the most commercially important antimony compound globally, accounting for the bulk of downstream antimony demand. The compound has three crystalline forms: cubic senarmontite (stable below 606°C) and orthorhombic valentinite (stable above 606°C), with a third amorphous form for specialty applications.

The compound matters because it is the single most important flame retardant synergist in the modern plastics, textiles, and electronics industries. When combined with halogenated (brominated or chlorinated) flame retardants, antimony oxide dramatically improves fire resistance performance in polymers. This is not optional chemistry. Fire safety codes across OECD countries, including IEC 60695 for electrical equipment, UL 94 for appliance plastics, and various EU and UK building regulations, effectively require flame-retardant systems that include antimony oxide for many product categories.

Beyond flame retardants, antimony oxide serves as a polymerisation catalyst for polyethylene terephthalate (PET) production, as a fining and clarifying agent in low-iron solar cover glass, as a white pigment base, and in specialty ceramic, paint, and pharmaceutical applications. The solar glass market has become a fast-growing outlet as global PV installations scale under IEA and IRENA tracking.

Global antimony oxide capacity is concentrated in China, with specialty production at Campine (Belgium), Clariant (Switzerland), Great Lakes Solutions (US, a Chemtura/LANXESS subsidiary), and smaller operations in Mexico, Bolivia, and Vietnam. Before 2024, Chinese producers supplied the majority of global merchant antimony oxide; the 2024-2025 export restrictions forced rapid supply chain reconfiguration.

Which Sectors Are Driving Antimony Oxide Demand?

Flame retardants in plastics: The dominant outlet. Used as a synergist with brominated and chlorinated flame retardants in ABS, PVC, polystyrene, polypropylene, polyurethane foams, and other polymers. Every electronic device housing, automotive interior, aircraft component, construction insulation panel, and flame-retardant textile potentially contains antimony oxide.

Flame retardants in textiles: Used in fire-resistant upholstery, protective clothing, theatrical and hospitality textiles, and aircraft and transportation interior fabrics. Regulatory drivers including US CPSC 16 CFR 1633 (mattress flammability) and EU building and transportation fire codes sustain demand.

PET polymerisation catalyst: Antimony-based catalysts (antimony trioxide, antimony triacetate, antimony glycolate) are used in the majority of global PET production for food and beverage packaging. This is a large-volume application where switching costs are high.

Solar glass fining agent: A growing application. Antimony oxide is used as a clarifying agent in low-iron solar cover glass manufacturing to remove bubbles and improve optical clarity. Global solar panel manufacturing scale directly pulls this segment.

Specialty ceramics and glass: Used in opaque glass enamels, opalescent glass, pigments, and specialty ceramic formulations. Smaller volumes but higher margins than commodity flame retardant grades.

Global Antimony Oxide Price Trend in 2025

Global antimony oxide prices experienced one of the most dramatic surges of any industrial chemical in 2025. Prices rose from USD 20.09/KG in Q1 to USD 27.99/KG in Q2 (+39.31%), then jumped again to USD 34.15/KG in Q3 (+22.01%). Q4 brought partial correction to USD 30.06/KG, and Q1 2026 stabilised at USD 28.21/KG.

The surge reflected pass-through from the upstream antimony metal market disruption. Since antimony oxide is produced by oxidising antimony metal, any shock to metal availability flows directly to oxide pricing, often amplified by the conversion step margin. China's September 2024 export licensing requirements for antimony metal and oxide, followed by the December 2024 ban on exports to the United States, created precisely this dynamic. Non-Chinese oxide producers like Campine and Great Lakes Solutions saw their metal feedstock costs spike, and passed those costs on.

The Q4 2025 and Q1 2026 correction suggests the market is stabilising at a new equilibrium. Alternative supply from Tajikistan, Bolivia, Myanmar, and recycled sources is partially filling the gap. However, prices remain roughly 40-50% above pre-2024 baselines and are unlikely to revert further without significant Chinese export policy relaxation, which appears unlikely in the current geopolitical environment.

European Antimony Oxide Price Trends in 2025

European antimony oxide prices followed the global pattern closely, with Q1 2025 opening at USD 19.36/KG, peaking at USD 34.90/KG in Q3 (+80.3% from Q1), then settling near USD 31.81/KG in Q1 2026. Europe's moderately volatile trajectory reflected continued licensed Chinese oxide imports combined with alternative supply development.

Europe's antimony oxide supply structure involves several integrated producers. Campine NV (Beerse, Belgium) is the largest European producer, operating from recycled antimonial lead battery material as a secondary source. Clariant (Switzerland) produces specialty grades for flame retardants. Additional volumes come from Spanish and Italian specialty chemical operations. European Commission Critical Raw Materials Act designation and the EU Strategic Technologies for Europe Platform have funded supply chain resilience programmes.

Downstream demand through 2025 was supported by European flame retardant requirements for automotive manufacturing (particularly EV applications), building materials, electronics, and aerospace. PET bottle manufacturing for beverages provided additional steady offtake. The Q1 2026 mild decline suggests the market is absorbing the new cost baseline, though European manufacturers face continued pressure given elevated energy costs and regulatory compliance burden.

South American Antimony Oxide Price Trends in 2025

South America saw the most dramatic Q3 2025 spike of any tracked region, with prices jumping from USD 31.00/KG in Q2 to USD 44.70/KG in Q3 (+44.20%). Q4 brought sharp correction to USD 37.49/KG, and Q1 2026 settled at USD 32.17/KG.

Bolivia has emerged as the single most important South American antimony source. The country is among the top five global antimony mine producers, with operations concentrated in the Potosí, Oruro, and La Paz departments. COMIBOL (Corporación Minera de Bolivia), the state mining company, oversees production alongside private cooperative and commercial operations. The Bolivian Ministry of Mining and Metallurgy reported increased investment interest in 2024-2025 as Western buyers sought non-Chinese supply.

The Q3 2025 spike reflected peak buyer anxiety and willingness to pay premium for supply-secured material. As alternative sources (Tajikistan, Myanmar) developed and Chinese oxide continued flowing to non-US buyers, the panic premium unwound. Brazilian and Peruvian demand for antimony oxide in PET manufacturing and flame retardant applications also contributed to the regional pricing pattern. Argentina, Chile, and Colombia are smaller consumers but have some specialty demand.

North East Asian Antimony Oxide Price Trends in 2025

North East Asia held the lowest regional pricing throughout 2025, reflecting Chinese domestic inventory buildup as export channels narrowed. The pattern follows the same counterintuitive logic seen in antimony metal: when exports are restricted, domestic inventory accumulates and pressures regional pricing lower, even as Western prices soar.

China produces the majority of global antimony oxide, with major facilities in Hunan, Guangxi, and Guizhou provinces. Hunan Gold Group, Hsikwangshan Twinkling Star, Guangxi Huaxi Group, and several smaller producers handle the oxide conversion from mined ore concentrates. When China's MOFCOM imposed export licensing requirements in September 2024 and banned US exports in December 2024, domestic Chinese oxide inventory built while Western prices surged. Japan and South Korea, both meaningful downstream consumers for flame retardant and electronics applications, tracked Chinese domestic pricing with modest import premiums.

The Q1 2026 very slight uptick of 1.03% suggests the domestic Chinese market may be finding balance, with inventory destocking potentially complete. Chinese domestic demand for flame retardants, PET catalysts, and solar glass fining remains substantial, providing a structural floor. Any future relaxation of export restrictions would tighten Chinese domestic availability and lift regional pricing, though this appears unlikely in the near term.

What Factors Drove Antimony Oxide Costs in 2025?

• Upstream antimony metal disruption: The dominant driver, through pass-through from the metal market crisis. China's export licensing requirements and US export ban directly affected oxide feedstock costs globally.
• Chinese export restrictions: Chinese oxide exports to non-US buyers continued under licence but at lower volumes and higher prices. US buyers faced particular acute pressure, forcing third-country transshipment and alternative source development.
• Defence and flame retardant demand: NATO defence spending increases and continued civilian flame retardant requirements sustained structural demand even as prices surged. Switching costs from antimony-based flame retardant systems are high.
• Solar glass expansion: Global solar PV installations continued growing per IEA data, with China, India, US, and European markets all expanding. Low-iron solar cover glass fining demand provided incremental pull.
• PET packaging demand: Food and beverage PET bottle production remained steady, providing baseline polymerisation catalyst demand. Recycled PET (rPET) adoption growth has moderated virgin PET catalyst volumes but not reversed them.
• Western supply chain development: Bolivia, Tajikistan, and secondary (recycled antimonial lead) sources all expanded during 2025 in response to the crisis. This gradually reduced the Western supply premium but did not eliminate it.

Antimony Oxide Market Forecast for 2026

The antimony oxide market forecast for 2026 points to continued elevated pricing with gradual normalisation as alternative supply sources mature. The Q1 2026 stabilisation around USD 28-32/KG globally suggests the market has found a working equilibrium above pre-crisis levels but below peak panic pricing.

On the upside, further Chinese export tightening, Bolivia political instability, or significant solar PV demand acceleration could lift prices. On the downside, continued alternative supply development, Chinese export policy relaxation, and PET recycling growth could pull prices lower. The defence and flame retardant demand base provides substantial price support.

Key Analyst Insights for the Antimony Oxide Market

Antimony oxide inherits its price dynamics from upstream metal markets, which are themselves shaped by Chinese export policy and critical minerals geopolitics. A few things worth tracking into 2026:

• Chinese MOFCOM export licensing decisions and US Department of Defense critical minerals funding.
• Global solar PV installation growth per IEA monthly data, which drives solar glass fining demand.
• PET recycling penetration, which moderates virgin polymerisation catalyst demand.
• European Commission Critical Raw Materials Act strategic projects and US IRA implementation for antimony supply diversification.
• Bolivian mining sector investment flows and political stability.
• Substitute flame retardant technology development (phosphorus-based, nitrogen-based systems).

Key Takeaways for Buyers and Manufacturers

For Buyers

• The USD 20-25/KG pricing of Q1 2025 is gone. Plan procurement around a new structural range of USD 25-35/KG globally.
• Qualify alternative sources across Campine (Belgium), Bolivia-sourced material, Tajik supply chains, and secondary (recycled) grades. Single-origin sourcing is now unacceptably risky.
• Consider phosphorus-based and nitrogen-based flame retardant alternatives where technical specifications permit. These can reduce antimony oxide dependency for specific product families.
• Lock in multi-year supply agreements with price indexation to antimony metal benchmarks. Flat-price contracts proved costly for buyers in 2025.

For Manufacturers

• Recycled antimonial lead feedstock is now a competitive advantage. Campine's secondary-sourced model is the template for supply resilience.
• Specialty high-purity grades for solar glass and pharmaceutical applications command growing premiums over commodity flame retardant grades.
• Backward integration into antimony metal refining (where feasible) captures more value chain margin in the current tight supply environment.
• Customer relationships matter more than ever. Long-term offtake with defence contractors, major PET producers, and solar module manufacturers provide revenue stability.
