Sodium Methyallyl Sulfonate (SMAS) is supplied as a white crystalline powder with a chemical formula of C4H7NaO3S and a guaranteed minimum purity of 99 %. The product is packaged in either 25 kg drums or 200 kg iron drums, both of which are palletised for safe handling during transport. SMAS functions as a high‑performance chain transfer agent in the manufacture of polycarboxylate super‑plasticisers used in concrete admixtures.
The compound is odour‑neutral and free‑flowing, traits that align with industry expectations for additives intended for concrete applications. Typical industry practice calls for SMAS to meet ISO and SGS certification standards, and the listing notes that such certificates are available on request. In the broader chemicals market, similar chain transfer agents are stored at ambient temperatures and exhibit comparable physical characteristics.
Primary users include manufacturers of ready‑mix, precast and high‑strength concrete who require enhanced workability and reduced water‑cement ratios. The supplier offers flexible minimum order quantities and ships under FOB or CIF terms, though exact quantities and lead times must be confirmed directly. Prospective buyers should request the latest safety data sheet and any test reports to verify compliance with their project specifications.

Before placing an order, verify the supplier’s certificates of analysis, ISO/SGS certifications and the most recent safety data sheet. Request a sample batch if possible and compare its analytical results against the stated 99 % purity to ensure consistency with your formulation requirements.
Discuss logistics early: confirm whether the shipment will be under FOB or CIF terms, agree on the port of discharge in China, and clarify the expected lead‑time based on current production capacity. Payment terms such as T/T in advance or LC at sight should be negotiated to align with your risk management policies.
Plan for quality control on arrival: arrange third‑party inspection to check drum integrity, verify labeling, and conduct moisture content testing. Ensure that the imported SMAS complies with any local regulatory standards and that all required import documentation, including the SDS and certificates, accompanies the shipment.
