Sodium alginate, listed as Sodium alginte, is a natural phycocolloid extracted from brown seaweed (Phaeophyceae) with the chemical formula (C6H7O6Na)n. It is supplied in food‑grade and pharmaceutical‑grade forms and carries the E401 food‑additive designation. The supplier, Qingdao Gather Ocean Seaweed Industry Co., Ltd, ships the product in bulk bags or drums for industrial use.
Food‑grade alginate typically contains a purity of 95 % or higher and exhibits a viscosity range of 150 - 300 mPa·s at a 10 % solution measured at 20 °C, making it suitable for thickening and gelling. Pharmaceutical‑grade material meets stricter impurity limits and is used in controlled‑release formulations. In the industry, alginate is valued for its ability to form stable gels at low concentrations and its resistance to microbial growth. Standard specifications also include a moisture content not exceeding 10 % and a degree of polymerisation between 100 and 200.
Major buyers include food manufacturers producing sauces, desserts and jellies, pharmaceutical firms formulating oral dosage forms, and textile printers requiring precise pattern fixation. Trade terms such as FOB or CIF are commonly offered, and payment methods like L/C or T/T are typical, but exact conditions should be confirmed with the supplier. Minimum order quantities and lead times are not disclosed in the listing; interested importers should request these details directly from Qingdao Gather Ocean Seaweed Industry Co., Ltd.

Before placing an order, verify the supplier’s harbour‑level trust tier and request copies of any certificates such as ISO or SGS that confirm product quality. Confirm the exact chemical specifications, including purity, moisture content and viscosity, by asking for a recent Certificate of Analysis. Checking these details helps ensure the material meets your formulation requirements and reduces the risk of non‑conforming shipments.
Discuss logistics early by agreeing on an incoterm that matches your supply chain, such as FOB or CIF, and clarify which party bears freight, insurance and customs duties. Ask the supplier about typical lead times and whether they can accommodate your production schedule. Payment terms like L/C or T/T are standard in the industry, but you should negotiate the specific conditions that suit your financing arrangements.
Arrange for a pre‑shipment inspection or third‑party laboratory testing to validate purity, viscosity and moisture levels against the agreed specifications. Request the supplier’s batch test reports and any relevant safety data sheets before the cargo leaves the port. Having documented quality checks and proper documentation in place will streamline customs clearance and protect your downstream manufacturing process.
