Wuhan Silworld Chemical Co., Ltd.

Wuhan Silworld Chemical Co., Ltd. is located in Wuhan, China and lists 108 active chemical products across the Chemicals & Allied Products, Industrial Chemicals and Salt categories. The catalogue spans organic iodine compounds, polymeric sucrose derivatives, sulfonate salts, crown ethers, per‑fluorinated sulfonamides and common inorganic salts, each identified with HS‑code families such as 2924, 2925, 2909, 3402 and 2843. The supplier’s portfolio includes both specialty organics like Diatrizoic Acid (HS 2924.29) and bulk inorganic materials such as Potassium Dichromate (HS 2841.50). Chinese chemical exporters of this breadth typically file export declarations under the same HS chapters and comply with national export licensing for dual‑use substances. The product list reflects a focus on intermediates used in pharmaceuticals, water treatment, electronics and polymer formulation.

The product entries provide detailed chemical formulas and, where supplied, HS codes that align with international tariff schedules. Examples include Sodium Vinylsulfonate (HS 2931.50, C2H3NaO3S) and Carboxymethyl Cellulose sodium salt (HS 3912.31) used as thickening agents in paints and detergents. Crown ethers such as 15‑crown‑5 (HS 2909.19) and dibenzo‑18‑crown‑6 (HS 2909.59) are listed for metal‑complexing applications in analytical chemistry. Per‑fluorinated sulfonamides like N‑Ethyl Perfluoro‑Octane‑Sulfonamide (HS 2904.99) are typical high‑purity reagents for surface‑active coatings. The catalogue does not mention any held certifications, so buyers should verify compliance with standard chemical trade requirements.

The catalogue covers a spectrum of organic and inorganic chemicals. Specialty organics such as Diatrizoic Acid and Sodium Diatrizoate are iodine‑based contrast agents that in the pharmaceutical market are required to meet purity grades of ≥99 % and water content below 0.05 %. Polysucrose 400 is a high‑molecular‑weight sucrose polymer commonly supplied with a moisture limit of 0.2 % and a degree of polymerisation around 400. Sulfonate salts like Sodium Propynesulfonate (HS 3402.39) and Sodium Dodecylbenzensulphonate are used as surfactants; typical industry specifications call for anionic charge density above 1 meq/g and a cloud point below 30 °C. Crown ethers and macro‑cyclic polyethers are sold with assay values of ≥98 % and are often supplied in sealed amber bottles to protect against UV degradation. Per‑fluorinated compounds such as Perfluorobutanesulfonyl Fluoride are provided in high‑purity grades (>99.5 %) for fluoropolymer processing, with standard handling instructions for moisture‑sensitive reagents.
