Sodium Naphthalene Sulphonate Formaldehyde (SNF) is a sodium salt condensate of naphthalene sulfonate formaldehyde used as a high‑range water‑reducing admixture in cement and concrete production. The product is supplied in 25 kg bags as well as 500 kg and 1000 kg jumbo bags, and it conforms to the standard specifications required for construction chemicals. It is marketed for fluid, plasticised, steam‑cured and waterproof cement applications, providing improved workability while lowering water demand.
The chemical belongs to the superplasticiser family of naphthalene‑based admixtures, typically offering a water‑reduction effect of 20‑30 % when dosed correctly. In the industry, a common dosage range is 0.3‑0.8 % of the cement weight, and the solid content is usually around 30 % by weight. Standard compliance is often referenced to ASTM C 494 Type A, which defines performance criteria for high‑range water reducers; SNF meets these typical benchmarks.
Primary buyers include precast manufacturers, ready‑mix concrete plants and suppliers of high‑strength structural concrete. The product is shipped in bulk, and buyers should confirm packaging integrity, incoterms and payment conditions before placing an order. Because the listing does not disclose minimum order quantity, lead time or pricing, interested importers are advised to request a formal quotation and any relevant test certificates from the supplier.

Before placing an order, verify the supplier’s corporate registration and any available third‑party audit reports. Request a sample batch accompanied by a certificate of analysis to confirm that the product matches the described specifications, including water‑reduction performance and solid content. Checking the packaging integrity and labelling for batch numbers also helps ensure traceability.
Importers should clarify the preferred incoterms, such as FOB Xiangyang port or CIF Shanghai, and agree on the expected lead time, which is typically between two to four weeks for bulk shipments once the order is confirmed. Payment terms are usually negotiated as a bank transfer or letter of credit, and it is prudent to align these terms with the supplier’s credit history and response reliability. Confirm freight options and any required export documentation early in the negotiation.
Quality assurance can be reinforced by arranging an independent third‑party inspection at the loading port, focusing on packaging condition, moisture content and correct labeling. Request a full set of documentation, including the MSDS, certificate of analysis, and any relevant conformity certificates such as ASTM compliance. These steps help mitigate risks and ensure that the received SNF meets the performance expectations for high‑strength concrete projects.
