International Market: South Africa’s growing demand drives global market
Due to the development of industry and infrastructure in South Africa, the demand for sodium hydrosulfide has increased significantly. The government plans to invest 100 billion rand in infrastructure projects such as energy and roads, and the demand for sodium hydrosulfide in metal anti-corrosion treatment has surged. The global market size in 2023 is about US$680 million, and it is expected to reach US$800 million in 2028, with a compound annual growth rate of 3.3%. The South African market has become an emerging growth point, attracting international companies to deploy.

Industry safety and environmental challenges
Hydrogen sulfide (H₂S) released during the production of sodium hydrosulfide is toxic and flammable, and the industry has recently strengthened safety control. China Report Hall pointed out that manufacturers need to use closed reaction equipment and supporting waste gas treatment technology to reduce environmental impact. At the same time, emerging markets such as South Africa are also facing pressure from upgraded environmental regulations during the industrialization process.

Application field expansion and technology upgrade
The downstream applications of sodium hydrosulfide continue to diversify. In addition to traditional textiles, papermaking, and metallurgy, the proportion of environmental protection fields (such as wastewater treatment) and high-end chemicals (organic synthesis) has increased. For example, the growing demand for anhydrous sodium hydrosulfide in the synthesis of pharmaceutical intermediates has driven companies to optimize production processes to improve purity. In addition, Chinese companies have reduced costs and enhanced their international competitiveness in the production of 32% liquid sodium hydrosulfide through petroleum by-product recovery technology.

Industry Outlook and Investment Trends
The global sodium hydrosulfide market presents a pattern of “Asia-Pacific-led, Europe and America stable, Africa emerging”. China accounts for 25% of the global market share, and major companies such as Luxi Chemical and Jingbo have consolidated their positions through capacity expansion. Investors are turning their attention to environmental technology upgrades and infrastructure dividends in emerging markets (such as South Africa). It is expected that from 2025 to 2030, the industry will accelerate integration, and technology-leading companies may expand their market share through mergers and acquisitions.
