The product is malonic acid, chemically known as propanedioic acid with the formula C3H4O4 and CAS number 141‑82‑2, supplied by Wuhan Silworld Chemical Co., Ltd. in China. It is a white crystalline solid with a reported assay purity of 99.5 % minimum, meeting the typical specifications required for pharmaceutical and agrochemical synthesis. The molecular weight is 104.06 g mol‑1 and the melting point ranges from 135 °C to 140 °C, values that are standard for high‑purity malonic acid. The supplier states that the chemical is exported in bulk bags or drums that comply with international transport regulations.
In the chemical industry, malonic acid of this grade is commonly used as an intermediate for drug intermediates, pesticide precursors and food‑grade acidulants. Typical packaging for bulk shipments includes 25 kg paper bags or 200 L steel drums, each sealed to prevent moisture ingress. Storage guidelines usually require a dry, well‑ventilated area with temperature control below 25 °C, which aligns with standard safety data sheet recommendations. Suppliers often provide ISO or SGS certification to demonstrate compliance with quality management systems, a typical practice for exported fine chemicals.
Pharmaceutical manufacturers, agrochemical producers and food processing firms are the primary buyers of this compound. Importers should confirm the exact assay method, such as HPLC, and request a certificate of analysis before loading the cargo. Trade is frequently conducted on FOB or CIF terms from major Chinese ports, with payment options including T/T or L/C after the commercial invoice is verified.

Importers should first obtain the certificate of analysis confirming the 99.5 % assay, along with the full material safety data sheet that details handling and storage requirements. Verifying the CAS number 141‑82‑2 and ensuring the product matches the described white crystalline appearance prevents confusion with similar dicarboxylic acids. It is also advisable to request a sample for laboratory validation when possible, especially for critical pharmaceutical applications.
Typical logistics involve loading the bulk bags or drums onto vessels departing from major Chinese ports such as Shanghai or Ningbo, with FOB or CIF incoterms being the usual trade terms. Buyers need to confirm the expected production lead time, which can vary with order size and any required custom specifications, and negotiate payment methods such as T/T in advance or an irrevocable L/C upon receipt of the commercial invoice. Clarifying these details early reduces the risk of delays.
Quality assurance commonly includes a third‑party inspection of the sealed containers and a review of the mill test report and any ISO/SGS certificates. Importers should stipulate a pre‑shipment inspection report and request all relevant customs documentation, including the certificate of origin and export declaration. Maintaining a complete record of these documents facilitates smooth customs clearance and supports downstream quality control in manufacturing processes.
