Magnesium thiosulfate (MgS2O3cap M g cap S sub 2 cap O sub 3

𝑀𝑔𝑆2𝑂3) is used as a specialized, highly soluble fertilizer providing magnesium and sulfur in a chloride- and nitrate-free form. 

Average Market Price (General): While specific, standardized spot prices for magnesium thiosulfate are not widely indexed in the provided results, similar sulfur-based liquid fertilizers and related magnesium products (like potassium thiosulfate or magnesium sulfate) indicate a wide price range depending on purity and volume, often in the range of $100 to over $1,000 per Metric Ton (MT).

Industrial/Agricultural Grade (Bulk): For agricultural applications,, Magnesium Thiosulfate (often in solution form) is quoted with negotiable rates per metric ton, usually requiring a minimum order quantity (MOQ) of 1 ton.

High-Purity/Lab Grade: High-purity (99%) Magnesium Thiosulfate is significantly more expensive, with smaller quantities (e.g., 1 kg) listed at over $1,000, suggesting a much higher price point for premium, non-agricultural, or technical grades
