II. Market Supply and Demand Analysis
- Supply Side:
- Domestic Capacity: China is the world’s largest producer of antimony trioxide, with total output reaching approximately 141,000 tons in 2025, up by 3.7% year-on-year. Major producers include Xikuangshan Shanxing Antimony Industry and Hunan Xingxing Antimony Industry, among others, exhibiting high market concentration.
- Raw Material Structure: Supply is primarily derived from primary antimony (mined ore) and recycled antimony (recovered from waste batteries and electronic waste). In 2025, the production ratio of primary to recycled antimony was approximately 2:1.
- Policy Impact: Since September 2024, China has implemented export controls on high-purity antimony oxide (purity >99.99%), tightening international supply; however, domestic supply has not been significantly affected.

- Demand Side:
- Key Application Areas:
- Flame Retardants: Accounting for over 85% of demand, antimony trioxide is used in plastics, rubber, and textiles, with significant growth driven by the plastics sector (e.g., cables and automotive interiors).
- Electronics Industry: High-purity antimony trioxide is utilized in semiconductor packaging, infrared detector materials, and 5G communication equipment, with demand accelerating due to the growth of new energy vehicles and 5G infrastructure.
- Ceramics and Metallurgy: Used as an additive in high-end ceramics (aerospace, medical devices) and metal smelting (as a deoxidizer for stainless steel), with steady demand growth.
- Demand Growth Drivers:
- Electronics Industry: China’s smartphone shipments are projected to reach XX billion units in 2025, driving demand for electronic components containing antimony trioxide.
- New Energy Sector: The advancement of photovoltaic and wind power projects is boosting demand for high-performance ceramic materials, indirectly increasing antimony trioxide consumption.
- Environmental Policies: Upgrades in traditional industries (e.g., improved deoxidation processes in metallurgy) are increasing the usage of antimony trioxide.

III. Analysis of Price Volatility Factors
- Short-term Decline Factors:
- Market Sentiment: Continuous price declines have led some downstream enterprises to adopt a wait-and-see approach, slowing procurement pace and weakening short-term demand.
- Inventory Pressure: Some manufacturers face accumulated inventory and have proactively lowered prices to liquidate stock and raise capital.
- International Market Linkage: Global antimony prices are volatile due to China’s export controls, but domestic demand remains stable, causing a time lag in the transmission of international price effects.
- Long-term Support Factors:
- Supply-Demand Balance: Domestic output in 2026 is expected to grow by approximately XX%, matching demand growth (XX%), indicating a relatively stable supply-demand relationship.
- Cost Support: Rising costs of antimony ore mining (due to increased environmental investments and declining resource reserves) provide a bottom support for antimony trioxide prices.
- Policy Orientation: Continued national support for new energy and new material industries ensures a clear long-term growth expectation for demand.

IV. Future Forecasts and Recommendations
- Price Trends:
- Short-term: Influenced by market sentiment and inventory adjustments, prices may continue to oscillate weakly, but the downward momentum is expected to narrow.
- Medium to Long-term: As downstream demand gradually materializes (particularly in electronics and new energy sectors), prices are expected to stabilize and recover. The compound annual growth rate (CAGR) from 2026 to 2030 is projected to reach XX%.
- Industry Recommendations:
- Manufacturers: Optimize capacity layout and increase the proportion of high-purity products (e.g., electronic-grade antimony trioxide) to enhance profitability.
- Downstream Enterprises: Monitor price fluctuation cycles and maintain reasonable inventory levels to reduce procurement costs; strengthen strategic cooperation with suppliers to ensure stable raw material supply.
- Investors: Pay close attention to technological upgrades and capacity expansion dynamics of industry leaders (such as Xikuangshan Shanxing Antimony Industry) to capture long-term investment opportunities.
