Sodium Metabisulfite For Industrial Grade
Zhongheng chemical Co., Ltd. supplies industrial‑grade Sodium Metabisulfite (Na₂S₂O₅) as a white to light‑yellow crystalline powder. The product meets a minimum purity of 96.5 % and contains iron below 0.005 %, arsenic below 0.0001 % and lead below 0.0005 %. Its solution pH lies between 4.0 and 4.6 and water insolubility is limited to 0.05 %. The material conforms to the standard industrial‑grade specification for reducing agents used in water treatment and related processes.
Typical industry practice accepts a purity window of 95‑98 % for industrial applications, with tighter limits for food‑contact uses. The low impurity profile makes the compound suitable for leather processing, textile bleaching and as a preservative in food‑related operations. Compared with alternative sulfite sources, this grade offers a stable, cost‑effective reducing capability.
Buyers usually receive the chemical in bulk bags or jumbo sacks, with packaging details to be confirmed directly with the supplier. As the listing does not disclose minimum order quantities, lead‑time or Incoterms, importers should request these trade terms before placing an order. The product’s documented specifications support its use in large‑scale industrial formulations where consistent performance is required.

Sourcing Sodium Metabisulfite For Industrial Grade from Zhongheng chemical Co., Ltd. - China Import Guide
Importers should first verify the batch Certificate of Analysis to ensure the declared 96.5 % purity and impurity limits are met. Request documentation on the supplier’s production process and any third‑party test reports that cover heavy‑metal content. Confirm that the material complies with any local regulatory limits for the intended end‑use.
Because the listing does not specify Incoterms or lead‑time, ask the supplier to clarify whether FOB, CIF or EXW terms are available and the expected shipment schedule. Discuss payment options such as Letter of Credit or Telegraphic Transfer and negotiate any advance payment requirements. Align the shipping port in China with your receiving port to minimise freight cost and handling time.
Arrange for a pre‑shipment inspection by an independent laboratory to confirm purity and impurity specifications. Request a full set of documents including the Material Safety Data Sheet, Certificate of Analysis and any applicable export licences. Retain these records for customs clearance and downstream quality assurance.
