Sulfanilic acid (C6H7NO3S) is an aromatic sulfonic acid used as a key intermediate in the production of azo dyes and pigments. Shijiazhuang Linxin Chem Co., Ltd. supplies it in industrial‑grade crystalline powder form. The supplier describes the material as high‑purity and suitable for large‑volume manufacturing. It is listed under the imported tier with a harbor trust rating.
Typical industrial grades achieve a purity of at least 98 % and a moisture content below 0.5 %. The powder is usually sieved to ≤100 µm particle size to ensure consistent dissolution. Solubility in water is about 10 g per 100 mL at 20 °C, which facilitates easy incorporation into aqueous dye baths. Standard packaging is offered in 25 kg drums or 500 kg bulk bags and the product should be stored in a cool, dry place.
End‑users include textile manufacturers, paper and leather processors, and pharmaceutical firms that require a reliable buffering agent. Buyers typically arrange bulk shipments and negotiate Incoterms such as FOB or CIF, but exact MOQ, lead time and payment terms must be confirmed with the supplier. Requesting a certificate of analysis and compliance with ISO or SGS standards is advisable before finalising the contract.

Before placing an order, verify the chemical’s purity, moisture content and particle‑size distribution by requesting a current certificate of analysis. Confirm that the packaging size (drum or bulk bag) matches your handling capabilities and that the product is stored in a suitable environment during transit.
Discuss logistics early: ask the supplier which Incoterms they can offer (e.g., FOB, CIF) and obtain an estimated lead time for production and shipment. Payment terms are not listed, so negotiate conditions such as T/T, L/C or open‑account based on your risk tolerance and the supplier’s policies.
Arrange for third‑party inspection if required, focusing on purity, moisture and packaging integrity. Documentation such as a material safety data sheet, test reports and any applicable ISO or SGS certificates should be obtained before final acceptance of the shipment.
