The product is a precipitated silica micro‑pearl grade (SiO2) manufactured by Wuxi Hengcheng Silicon Industry Co., Ltd. in China. It is produced by reacting sulfuric acid with sodium silicate and applying pressure spray drying technology, which creates a spherical, non‑dusting particle form. The process results in a material with high surface area and reinforcing properties that are valued in rubber and silicone formulations. The company lists the commodity under HS code 2811.22 for global trade.
Wuxi Hengcheng describes the silica as denser than conventional powder, making it easier to handle during mixing. In the broader industry, micro‑pearl silica typically exhibits particle sizes between 5 µm and 30 µm and a specific surface area around 200 m² g⁻¹, both of which enhance filler performance. Typical bulk density for this grade is about 0.6 g cm⁻³ and moisture content is kept below 0.5 %. These parameters are standard for silica used in tire tread compounds and footwear soles.
The material is mainly used in tire manufacturing, footwear production and other industrial rubber goods where reinforcement and low dust generation are required. International buyers often request packaging in paper bags, big bags, or bulk in lined containers placed on plastic or wood pallets, as offered by the supplier. Prospective importers should confirm the minimum order quantity, lead time and incoterms directly with the supplier before finalising a purchase.

Before placing an order, importers should request the latest material safety data sheet and a certificate of analysis that confirms particle size, surface area and moisture content. Verifying that the product is produced by pressure spray drying and that the supplier’s harbor trust tier is active can reduce the risk of receiving off‑spec material. It is also advisable to arrange a small trial shipment to assess handling characteristics.
Buyers need to confirm the preferred packaging format, the loading port and the incoterm - commonly FOB or CIF - for the shipment. Lead times are not disclosed in the listing, so they should be clarified directly with the supplier. Payment terms such as T/T in advance or a letter of credit should be agreed upon before finalising the contract.
A third‑party inspection is recommended to check bulk density, particle size distribution and moisture content upon arrival. Requesting a post‑shipment test report ensures the silica meets the agreed specifications and complies with HS code 2811.22. Proper documentation, including the certificate of origin and customs invoice, will streamline clearance at Chinese ports.
