Sodium sulfite (Na2SO3) is a white crystalline inorganic compound supplied by Lianyungang Huaihua International Trade Co., Ltd. The product is offered in industrial, food and photo grades with purities reported between 95% and 98%. It is packaged in 25 kg bags, 50 kg bags or larger jumbo bags for export shipments.

The three grades differ mainly in allowable impurity limits, with food‑grade material meeting stricter standards for residual metals.

Suppliers often certify compliance with ISO 9001 and SGS audit requirements, and the listing states that these certifications are held. Typical storage conditions call for a cool, dry environment to maintain stability.
Key users include pulp and paper mills, water‑treatment facilities, textile manufacturers and pharmaceutical formulators. Buyers usually place orders starting from a single 25 kg bag, with larger volumes arranged on request. Shipping terms such as CIF or FOB are negotiable and the supplier can arrange container loads for bulk purchases.
