Top 10 Companies in the Sodium Arsenite Market (2026): Market Leaders Powering Global Chemical Supply

MARKET INSIGHTS

Global Sodium Arsenite market size was valued at USD 12.5 million in 2025 and is projected to grow from USD 12.9 million in 2026 to reach USD 18.2 million by 2034, exhibiting a compound annual growth rate (CAGR) of approximately 4.1% during the forecast period. The U.S. market, a significant regional segment, was estimated at USD 3.1 million in 2025, while China is projected to be a key growth market.

Sodium Arsenite is an inorganic compound with the formula NaAsO₂, primarily recognized for its role as a preservative and an analytical reagent. This chemical is crucial in specific industrial processes, most notably in the preservation of wood and hides, where it acts as a potent insecticide and fungicide. Its use as an analytical reagent is rooted in its redox properties, making it valuable in certain titrimetric analyses within laboratory settings. The market is segmented by purity grades, with Purity ≥ 98% and Purity ≥ 99% being the primary classifications that cater to different application requirements.

The market’s growth trajectory is influenced by a complex interplay of factors. While demand from specific industrial preservation applications provides a baseline, the market faces significant headwinds due to the stringent regulatory environment governing the use of arsenic compounds because of their high toxicity and environmental persistence. However, its continued, albeit niche, application in precise analytical chemistry supports a steady demand. The competitive landscape is concentrated, with key players such as SCP SCIENCE, Jiangxi Qianhua Industry, and Hangzhou Keying Chem accounting for a significant portion of the global market revenue. The Purity ≥ 98% segment is anticipated to show substantial growth, driven by its cost‑effectiveness for industrial applications.
