Import Barium Sulfate — Buy in wholesale FOB from Supplier in China

Shijiazhuang Chenshi Import And Export Co., Ltd. offers precipitated barium sulfate manufactured from purified barite ore at their processing facility in Hebei Province, China. The material presents as a fine white powder with minimum 98.5% BaSO4 content and minimum 98% whiteness, positioning it in the higher purity tier of industrial grades. Key measured parameters include density of 4.5 g/cm3 minimum, oil absorption of 13 g/100g, and a tightly controlled D50 particle size of 0.5-0.7 µm. These specifications indicate suitability for gloss coatings, inks, and polymer applications where fine particle distribution and colour neutrality are critical performance factors.

The production route, purification of barite through chemical processing, yields a synthetic precipitated product rather than mechanically milled natural ore. This method achieves the extremely narrow particle-size range referenced in the source, a characteristic difficult to attain through conventional grinding alone. The low specific surface area contributes to good wettability and reduced dispersant demand in liquid systems. Impurity controls are tight: Fe2O3 maximum 0.004%, Al2O3 maximum 0.01%, silicate maximum 0.01%, and heavy metals maximum 0.01%. The low Mohs hardness of barium sulfate (inherent to the mineral, not separately stated) means low abrasion during processing, protecting milling equipment and extending maintenance intervals in continuous production environments.

Primary applications for this grade include high-gloss paint and coating systems, printing inks, rubber compounding, paper filling and coating, plastics modification, and battery manufacturing. The 0.5-0.7 µm D50 sits within the optimal range for TiO2 extension and spacing in decorative coatings. Battery sector buyers may value the low heavy metal and salt-soluble content for electrolyte-adjacent components. Standard packaging is 25 kg bags with custom options available. Importers should confirm whether the supplier provides surface-treated versions, such as stearic acid or silane coating, for improved compatibility in hydrophobic polymer matrices.

Shijiazhuang Chenshi Import And Export Co., Ltd. is based in Shijiazhuang City, Hebei Province, China, with a listed postal code of 050000. The company's profile indicates it operates as an import and export trading firm, suggesting either direct manufacturing with export licensing or merchant trading of chemically processed minerals. The harbor trust tier reflects basic platform verification. The response rate and average response hours both show zero, which may indicate limited platform transaction history or that response metrics have not yet accumulated from buyer inquiries. The address places the company in a provincial capital with access to Hebei's chemical industry cluster and logistics networks serving Tianjin and Qingdao ports.

The listing provides unusually detailed technical data for barium sulfate, including precise impurity limits and a narrow D50 specification that implies precipitated rather than ground natural product. The company states capability to follow customer designs for packaging, indicating flexibility for branded or specialized delivery requirements. No manufacturing capacity, export volume, or certification scope appears in the available profile. Buyers should verify whether Chenshi operates the precipitation plant directly or sources from dedicated manufacturers, and whether they can provide batch-specific certificates of analysis with accredited laboratory backing. The 24-month recommended storage life suggests the supplier understands product stability, though actual shelf life depends on storage conditions.
