In the second quarter of 2026, the monthly average antimony trioxide price in China was ~RMB 193.77/kg in April and ~RMB 176.62/kg in the subsequent month, showing a decrease of ~8.9%. Prices fell as a greater supply of antimony intermediates from local smelters and lower demand by consumers in the flame retardants and polymers industries. Meanwhile, the monthly average antimony trioxide price in India was ~INR 2,718.14/kg in April and ~INR 2,479.57/kg in the subsequent month, showing a decrease of ~8.8%. Lower prices were driven by Asian import activity, where Indian consumers bought fewer antimony intermediates because they had adequate stock levels and steady but stagnant demand from the plastics and cable insulation industries.
Analyst Insight
According to Procurement Resource, antimony trioxide prices are expected to remain under pressure with periodic stabilization attempts, driven more by supply normalization and inventory correction cycles than any meaningful rebound in the end user demand.

In China, antimony trioxide prices remained firm through Q1’26 as tight upstream antimony availability and cautious producer selling supported the market. According to the U.S. Geological Survey, global antimony mine production in 2025 was estimated at around 100,000 metric tonnes, highlighting a highly concentrated supply base and China’s critical role in the market. Domestic supply stayed tight because ore availability remained limited, mining controls continued, and replenishment of smelter raw materials was slow. Demand from flame retardants, the largest end-use sector, remained stable, while photovoltaic glass provided additional support because antimony trioxide is processed into sodium antimonate for clarifying applications. Export demand also improved earlier in the quarter, helping support sentiment, though downstream buyers largely maintained need-based procurement and showed limited tolerance for elevated prices.
Antimony trioxide is an inorganic compound that is essential in a number of industrial applications as a flame retardant. It helps in the formation of a protective char layer and lowers the flammability of materials like plastics and fabrics. Because of its high density, low water solubility, and thermal stability, it may effectively increase fire resistance in a variety of goods and materials.

In the first step of the reaction, the process of the conflagration of antimony trisulfide occurs, which is followed by incineration. Then, smelting the contents in a plasma arc furnace followed by dossing, sintering, and melting at elevated temperatures to produce antimony trioxide.
