Changsha Weichuang Chemical Co., Ltd supplies Sodium Metabisulfite, a white crystalline inorganic compound with formula Na2S2O5. The chemical is also referred to as sodium pyrosulfite and is offered in both food‑grade and industrial‑grade specifications. The listing cites a minimum purity of 97 % for the product. The supplier operates from Changsha, Hunan Province, China and carries a harbor trust tier, with a recorded response rate of 0 %.
Sodium Metabisulfite functions as a bleaching agent in textile processing, a preservative (E223) in food products, and a dechlorination agent in water treatment. Typical industry specifications call for a moisture content below 0.5 % and a bulk density around 1.5 g cm‑3, values that buyers usually verify through a Certificate of Analysis. The material should be stored in a dry environment, protected from strong acids and oxidising agents, at temperatures between 15 °C and 25 °C to prevent degradation. Standard bulk handling often involves 25 kg paper bags or 1‑ton flexible intermediate bulk containers, which facilitate large‑scale shipments.
Customers such as beverage manufacturers, textile dye houses and municipal water treatment facilities commonly import this chemical. Trade terms are negotiated per inquiry, with pricing dependent on order volume and current market conditions; the supplier mentions flexible MOQs and the ability to ship under CIF or FOB arrangements. Prospective buyers should confirm the exact minimum order quantity, desired Incoterm, and preferred payment method directly with Changsha Weichuang before finalising the contract.

Before committing to a purchase, confirm the declared purity, grade and packaging details with Changsha Weichuang Chemical and request a recent Certificate of Analysis. Verify that the product meets any food‑grade specifications required for your application and clarify the minimum order quantity, which is not disclosed in the listing.
Discuss logistics early by agreeing on Incoterms such as FOB or CIF, and ask for an estimated lead time from the Changsha manufacturing site to your destination port. Because the supplier’s response rate is currently 0 %, obtain a clear timeline for order confirmation and shipment to avoid unforeseen delays.
Arrange for an independent inspection or laboratory verification upon arrival to ensure moisture content, purity and absence of contaminants meet your standards. Ensure the supplier can provide all necessary import documentation, including safety data sheets and customs paperwork, to facilitate smooth clearance in your target market.
