Import Calcium Thiosulfate — Buy in Bulk from Supplier in Canada

Calcium Thiosulfate from M Trading is a water-soluble compound supplied as a clear to pale yellow solution, with the CAS number 10124-41-1 and molecular formula CaS2O3. The product has a molecular weight of 152.208 g/mol, delivered in concentrated form for direct application in agricultural and industrial systems. It is compatible with most liquid fertilizers and foliars, making it a practical choice for integrated nutrient management programs.

This grade is used primarily as a soil conditioner and sulfur source, supplying plant-available sulfur and calcium while aiding in the breakdown of residual pesticides. Typical agricultural formulations contain 12-15% sulfur and 8-10% calcium by weight, though the exact concentration for this listing should be confirmed with M Trading. The solution remains stable under normal storage conditions but may crystallize at temperatures below 0°C, requiring gentle heating to redissolve.

Buyers in row crop farming, horticulture and specialty agriculture use it to correct sulfur deficiencies and improve soil structure. Industrial users apply it in water treatment for chlorine neutralisation and in chemical manufacturing for sulfur-based reactions. The product is shipped in bulk liquid tankers or IBC totes, with packaging and lead times subject to confirmation. Incoterms and payment terms are agreed on a per-order basis, with L/C and T/T commonly supported.

M Trading is an imported-tier supplier based in Canada, listed under the harbor trust tier. The company’s profile indicates it operates as an importer or distributor of chemical products, with no additional verification signals such as response rate or average response time currently available. The supplier’s focus appears to be on providing industrial and agricultural chemicals, including specialty compounds like Calcium Thiosulfate.

While the profile does not disclose specific certifications, the product description references ISO standards as part of its quality assurance framework. Buyers should verify the supplier’s compliance documentation and request certificates of analysis for each batch. The absence of response metrics suggests direct outreach may be necessary to confirm trade terms, including MOQ, lead times, and incoterms.
