Sodium Metabisulfite (Na2S2O5) supplied by Sdoc Resources Co., Limited is a white crystalline powder. The listing specifies a food‑grade variant with a minimum purity of 98 % and an industrial‑grade variant without a stated purity limit. Both grades are produced primarily in China and India and are packaged in either 25 kg or 50 kg woven bags, with the option of 1 ton bulk bags for large orders. The material is marketed for its bleaching, preservative, antiseptic and mordant properties across several process industries.
In the chemical commodity market the typical moisture content of Sodium Metabisulfite is below 0.5 % to ensure stability. Standard bulk density ranges from 1.4 to 1.5 g cm‑3 and the powder is normally supplied with a particle size of 200 µm or finer. Typical storage conditions require a dry, well‑ventilated area away from strong oxidising agents and temperatures below 30 °C.
Food processors use the 98 % grade as a leavening and antioxidant agent, while textile manufacturers rely on the industrial grade for mordanting and de‑chlorination. Importers generally target bulk buyers such as food‑ingredient distributors, textile dye houses and water‑treatment firms. Trade is usually conducted on FOB or CIF terms, with shipment in the offered bag sizes; exact MOQ, lead time and payment conditions should be confirmed directly with the supplier. Buyers are advised to request a Certificate of Analysis for each batch to verify purity and to arrange third‑party inspection if required.
