Antimony & Antimony Trioxide Market Size and Growth Report, 2033

Antimony & Antimony Trioxide Market Overview

The Antimony & Antimony Trioxide Market size was valued at USD 751.71 million in 2024 and is expected to reach USD 1011.69 million by 2033, growing at a CAGR of 3.3% from 2025 to 2033.

The global antimony and antimony trioxide market is driven by robust demand in fire retardant and catalyst industries, where over 75,000 metric tons of antimony trioxide are used annually for flame retardant applications. Antimony metal, primarily sourced from stibnite ore (Sb2S3), is converted to antimony trioxide (Sb2O3) through oxidation processes. China dominates antimony mining and refining, producing approximately 60,000 metric tons in 2023, which is over 70% of the global supply.

Demand from the flame retardant segment alone accounted for over 50,000 metric tons globally in 2023, with automotive and electronics sectors leading usage. Regulatory restrictions in Europe on halogenated retardants are further increasing the shift towards antimony-based formulations. The catalyst industry consumed approximately 12,000 metric tons of antimony trioxide in 2023, majorly in polyethylene terephthalate (PET) manufacturing.

New entrants in the high-purity grade sector are boosting product innovation to meet growing semiconductor and battery-grade requirements. Environmental regulations surrounding antimony leaching in soil and water continue to shape production technologies and recycling systems. The U.S. maintains strategic reserves exceeding 2,000 metric tons of antimony to mitigate supply chain risks due to heavy reliance on Chinese imports.

Key Findings

DRIVER: Rising demand for flame retardants in construction and electronics.

COUNTRY/REGION: China dominates with over 60% of global antimony production.

SEGMENT: Flame retardant grade antimony trioxide accounts for the highest market share.

Antimony & Antimony Trioxide Market Trends

One major trend is the increased demand for antimony in flame retardant applications for construction materials, where it is used in insulation, cables, and structural plastics. In 2023, over 55,000 metric tons of flame retardant-grade antimony trioxide were used globally. The global building and construction sector experienced a 9% rise in fire-safety material consumption in 2023, contributing to this growth. Another trend involves the rising use of ultra-fine particle grade antimony trioxide in electronics. Approximately 4,200 metric tons were consumed in microchip and printed circuit board applications last year. Regulatory actions in the European Union and California have stimulated this growth by banning specific halogenated flame retardants, boosting alternatives that include antimony trioxide as a synergist. High-purity antimony trioxide is gaining traction in battery technologies, especially as a component of solid-state electrolyte materials. Over 3,000 metric tons of high-purity grade material were used in energy storage applications in 2023, with significant investments in R&D from Japan and South Korea. Additionally, recycling rates of antimony from lead-acid batteries and industrial scrap reached 25% in 2023, showing progress towards circular economy goals. On the supply side, the global production of antimony has been challenged by declining ore grades. The average ore grade dropped from 1.2% Sb in 2018 to 0.9% Sb in 2023, prompting increased exploration in Russia and Bolivia. Meanwhile, geopolitical tensions and China’s export restrictions on critical minerals have caused a 7% rise in international antimony prices during Q2 of 2023. In terms of manufacturing, companies are shifting towards cleaner roasting and chlorination techniques to reduce toxic emissions. Around 38% of Chinese refineries have adopted low-emission technologies by the end of 2023. Investments in water treatment systems for antimony removal have increased in Canada and Germany due to stringent environmental norms.

Antimony & Antimony Trioxide Market Dynamics

The dynamics of the antimony and antimony trioxide market are shaped by evolving industrial applications, supply constraints, environmental regulations, and emerging technologies. Market forces such as growing demand from flame retardant and battery industries are fueling expansion, while environmental scrutiny and geopolitical supply risks are posing significant barriers.

DRIVER

Rising demand for flame retardants in fire-prone construction zones

The primary driver of the antimony & antimony trioxide market is the growing demand from the flame retardant industry. In 2023, global fire-related damages surpassed $65 billion, intensifying the need for advanced fire-proof materials. Antimony trioxide, as a synergist, enhances the efficiency of halogenated flame retardants. Its use is predominant in building panels, textile coatings, automotive interiors, and electronics. For example, over 42% of plastic-based insulators in residential constructions in North America incorporated antimony-based compounds. Additionally, governments such as those in Germany and South Korea have introduced mandatory fire-safety regulations, which are pushing manufacturers to adopt antimony trioxide in cables and polymer formulations. This demand is particularly high in urban infrastructure projects, with over 15,000 metric tons allocated for commercial buildings in Asia-Pacific in 2023.

RESTRAINT

Environmental toxicity and regulatory scrutiny

The biggest restraint in the market is increasing environmental and health regulations against antimony usage. Antimony trioxide is classified as a possible human carcinogen by several environmental bodies. In 2023, the European Chemicals Agency (ECHA) restricted imports of over 2,000 metric tons of non-compliant antimony compounds. Moreover, rising soil contamination levels near antimony refining units in China and India triggered enforcement of strict emission standards. The U.S. Environmental Protection Agency (EPA) has limited antimony concentration in drinking water to 6 ppb, prompting manufacturers to adopt cleaner technologies. Antimony’s low biodegradability has led to several countries mandating recycling procedures, thereby increasing operational costs. Compliance with environmental norms added up to $18 million in capital expenditure for top producers in 2023 alone.

OPPORTUNITY

Increasing application in battery and renewable energy sectors

A major opportunity lies in the energy storage and renewables sector. Antimony-based alloys are increasingly used in lead-acid batteries, which continue to dominate grid-scale storage applications. In 2023, over 1.1 billion automotive and stationary batteries were produced globally, with 35% containing antimony as a strengthening agent. The high-purity antimony trioxide is also being studied for its role in sodium-ion and lithium-sulfur batteries. In Japan, two pilot plants testing antimony-based electrolyte materials consumed over 280 metric tons in 2023. Additionally, solar glass manufacturing used nearly 2,400 metric tons of antimony trioxide for enhancing UV stability. The push toward decarbonization by 2030 is expected to drive significant demand from the energy infrastructure sector, especially in Europe and East Asia.

CHALLENGE

Declining ore grades and concentrated supply chains

A persistent challenge is the limited number of high-grade antimony ore mines. Global antimony reserves were estimated at 1.8 million metric tons in 2023, with over 50% located in China. The average ore grade has declined from 1.5% in 2015 to 0.9% in 2023, increasing extraction and refining costs. This has led to higher dependency on recycling and low-grade ore beneficiation technologies. Additionally, supply chains are highly concentrated, with more than 60% of the world’s smelting capacity based in China. Trade restrictions and tariffs have caused logistical delays, impacting the availability of antimony in North America and Europe. In Q4 2023, antimony prices spiked by 11% due to export quotas announced by the Chinese Ministry of Industry.
