Zhangzhou Zhoushun International Trade Co., Ltd. supplies ion‑exchange membrane grade caustic soda flakes with a sodium hydroxide purity of 98‑99 %. The product is delivered as solid white flakes packaged in 25 kg polypropylene bags or 1000 kg jumbo bags. It originates from the Huli Economic Technology Development Zone in Zhangzhou, Fujian, China. The flakes are intended for bulk industrial use and are classified as a hazardous alkaline material.
Membrane‑grade caustic soda offers higher purity than diaphragm or mercury cell grades, meeting most pharmaceutical and food‑processing standards. Typical moisture content for flake grade is below 0.5 % to maintain flowability, and bulk density usually ranges from 0.80 to 0.90 g cm‑3. The material is highly hygroscopic, so manufacturers store it in moisture‑proof, air‑isolated containers. Standard industry practice recommends handling with corrosion‑resistant equipment.
Common applications include pulp and paper pulping, textile dyeing, water‑treatment neutralisation, and food‑grade processing where alkali strength is critical. Buyers are generally chemical distributors, large‑scale manufacturers, and utility companies that require sealed packaging to prevent CO₂ absorption. The supplier indicates FOB terms and bulk volumes are typical, but exact minimum order quantities are not disclosed in the listing. Prospective importers should confirm packaging details, shipping incoterms and payment methods directly with the supplier.

Before placing an order, verify the exact grade and purity certificate for the membrane‑grade caustic soda, and confirm that the packaging dimensions match the 25 kg or 1000 kg specifications. Request a recent material safety data sheet (MSDS) and ensure the supplier can provide a batch analysis report. Clarify whether the product is stored in sealed, moisture‑proof containers at the warehouse to maintain the stated purity.
Discuss the preferred incoterm, typically FOB from the port of Xiamen or Zhangzhou, and ask the supplier to outline the expected loading schedule. Lead times for bulk chemical shipments can range from two to four weeks, depending on production and customs clearance. Payment terms are usually T/T against a commercial invoice, but negotiate any letter of credit requirements in advance.
Arrange for an independent third‑party inspection before vessel loading, focusing on visual appearance, moisture content and purity verification. Request the inspection report to be attached to the shipping documents, along with the certificate of analysis. Ensuring these documents are present will help streamline customs clearance and downstream processing.
